Smart prosthetic hand combines both human and robot control

Zhuang et al. Shared human–robot proportional control of a dexterous myoelectric prosthesis. Nature Machine Intelligence, September 2019.

Holding an object in your hand might seem easy, but it’s actually a very complicated and challenging task; if, for instance, an object starts to slip, you typically have a couple of milliseconds to react. Scientists have been trying new approaches for improved control of robotic hands, particularly for use by amputees. A recent technology was able to combine individual finger control and automation for improved grasping and manipulation by successfully merging the fields of neuroengineering and robotics. This interdisciplinary approach was tested on three amputees and seven non-amputee subjects. The neuroengineers achieved the intended finger movement from muscular activity on the amputee’s stump, allowing for individual finger control of a prosthetic hand, which had never been done before. The robotics team enabled the robotic hand to take hold of objects and maintain contact with them for robust grasping. The amputee first performed a series of hand movements in order to train the algorithm through a machine learning paradigm. This taught the algorithm to decode user intention and translate it into finger movements of the prosthetic hand. Concurrently, sensors placed on the amputee’s stump detected muscular activity, which trained the algorithm to learn which hand movements corresponded to which patterns of muscular activity. Once the user’s intended finger movements were acquired, this information could then be used to control individual fingers on the prosthetic hand. When the user tried to grasp an object, the robotic automation initiated. The algorithm told the prosthetic hand to close its fingers when an object was in contact with sensors on the hand’s surface. This automatic grasping was designed to infer the shape of objects and grasp them based on tactile information alone, without any help of visual signals. The robotic hand has the ability to react within 400 milliseconds, and it is equipped with pressure sensors all along the fingers: it can react and stabilize the object before the brain can actually perceive that the object is slipping. While this promising technology can be used in in several neuro-prosthetic applications such as bionic hand prostheses and brain-to-machine interfaces, there are still many challenges remaining to implement this technology in a commercially available prosthetic hand for amputees. It is currently being tested and improved.

Cats securely bond with people, too

Vitale et al. Attachment bonds between domestic cats and humans. Current Biology, September 2019.

Dogs have long been regarded as man’s best friend. They’re sociable, faithful, and obedient. Cats, on the other hand, are often described as more aloof, mysterious, and independent. But a new study suggests that cats actually bond with their owners in similar ways to how humans and dogs bond with companions. The most established way to study human attachment behavior is to observe an infant’s response to a reunion with their caregiver following a brief absence in a novel environment. When a caregiver returns, secure infants quickly return to relaxed exploration while insecure individuals engage in excessive clinging or avoidance behavior. These tests had been previously run with humans, primates, and dogs; researchers decided to run the same test with cats. 79 kittens and 38 adult cats and their caregivers were recruited. During the test, an adult cat or kitten spent two minutes in a novel room with their caregiver followed by two minutes alone. Then, they had a two-minute reunion. The cats’ responses to seeing their owners again were classified into attachment styles. The results show that cats bond in a way that’s surprisingly similar to infants. In humans, 65% of infants are securely attached to their caregiver and domestic cats and kittens mirrored this, as about 65% of them securely bonded to their people. After the first round of tests, the researchers enrolled half the kittens used in the study in a training and socialization course. The other half served as a control group. Researchers then found the same results, suggesting the training did not have an effect on kittens’ attachment behavior toward their owners. This indicates that once a cat forms a bond, it seems to remain stable over time. This social flexibility may have helped facilitate the success of the species in human homes. It is still not clear what the factors are that shape the caretaker relationship, but it’s likely a miraculous complex mix of genetics, personality, and experience.

An efficient and green way to convert heat into electricity

Zheng et al. Paramagnon drag in high thermoelectric figure of merit Li-doped MnTe. Science Advances, September 2019.

A recent discovery could help scientists to develop more efficient ways to generate electricity from heat that would have been otherwise wasted, such as heat coming from car exhaust, industrial processes, and interplanetary space probes. In principle, magnetic fields can be used to generate electricity. If we move a magnet through a coil or wire, the magnet pushes and pulls electrons that create an electrical current. Magnets themselves don’t have energy, but they can control energy currents through the created magnetic field. The main problem with magnets is that when a magnet is heated up, it loses most of its magnetic properties and becomes a so-called paramagnet. Until this discovery, scientists believed that paramagnets couldn’t be used for generating electricity. In the new study, researchers found a way of designing thermoelectric semiconductors that can convert heat to electricity. The tiny particles in paramagnets, so called paramagnons, ended up producing enough spin to push an electron, for only a billionth of a millionth of a second – apparently long enough to make paramagnets viable energy-harvesters. This breakthrough in the conventional understanding of magnetic properties could lead to more research into how magnets and energy interact to potentially facilitate electricity production from heat that is otherwise wasted and oftentimes harmful to the environment.

Question: “There is no greater title and position than servanthood to God. Even if there is, it must be freedom, which is actually another dimension of this servanthood.” In our age when everybody talks about freedom, what is freedom, from a believers’ perspective?

Answer: A person who becomes a true servant to God is freed from all types of servanthood which might sometimes even make them knock every door like a beggar and resort to mean ways. That person will similarly not be a slave to passing fancies and desires.

Obstacles to freedom

As for people who fail to be servants to God in the true sense, they may sometimes become slaves to their desires and lust and thus lead a bohemian life. Sometimes they give in to their greed and engage in different speculations for the sake of amassing wealth, without caring whether it is lawful or not. Sometimes, they give in to a desire for worldly status and titles and thus seek to allocate the people’s wealth for themselves by abusing their position.

People who do not lead their life with a profound consciousness of servanthood sometimes become slaves to their envy and cannot even tolerate people dedicated to good acts who try to conquer hearts. Because of this intolerance, they burn with a desire to sabotage their work. However, they actually do the greatest harm to themselves. As they eat their hearts out before the accomplishments of the people they envy, they also ruin their own deeds with respect to the Hereafter. Note that the noble Prophet stated that malicious envy consumes one’s good deeds, like fire consumes wood (Abu Dawud, Adab 44; Ibn Majah, Zuhd 22).

Fame is another pitfall for those who are not true servants to God. Seekers of fame try every means for the sake of being the center of attention and for receiving applause and appreciation. If such poor ones make the slightest achievement or make the slightest degree of sacrifice, they immediately expect some others to say, “the entire country is proud of you.” They do not talk without applause, and do not give anything without receiving compliments. They go through fits of delight and are enraptured in the face of applause. Such people with egotistic souls actually become servants and slaves to fame.

Other than that, there are also people who become slaves to ease and comfort, to money and wealth, to benefits and opportunism… Such unfortunate ones who fail to savor and appreciate the worth of the servanthood to God keep running after their own ambitions, greed, desires, passions, and addictions. They knock all doors and try every possible reference. However, they cannot feel satisfied nor find true happiness in any way. Actually, what lies in the root of idolatry is weakening of the feeling of servanthood to God. Since idolaters cannot properly be servants to God and cannot savor the delight of servanthood, they resort to different means in order to satisfy this hunger of theirs. With the added influence of some devilish considerations, they, for example, posted a stick on the ground hoping to make rain fall; they resorted to beseeching those in the grave for realizing some other wish; they wanted to realize their goals by means of pieces of cloth or candles they left in tombs; but they gradually fell into the pitfall of associating partners with God.

Some others objected to servanthood to God, claiming that this—God forbid—goes against human dignity. They claim that a person who observes servanthood to God becomes accustomed to servanthood and might be a servant before the created also. Namely, they mistook servanthood to God as contradictory to freedom. Actually, attaining true human freedom depends on this very point. A person can be freed from other servanthood only by becoming a servant to God. It firstly needs to be acknowledged that a person chooses faith with free will and believes in the essentials of faith with free will. The person similarly observes worship with free will. In short, a person observes servanthood to God out of free will.

In this respect, there is a very close relation between freedom, worship, and profound devotions. While those unable to throw off the shackles around the neck imposed by fame, hedonism, and the like cannot ever be free, they can neither be servants to God in the true sense. Namely, as freedom is crucial for the sake of thorough servanthood to God, attaining real freedom depends on being a servant to God in the true sense.

Given that God Almighty endowed humanity with a very significant dynamic like free will, it matters where and how we use it. One must aim for great wishes and demands with free will. Seeking simple worldly delights and pleasures would hurt human honor and dignity; running after trivial things would be a bad investment for the capital of a lifetime. What suits a proper human being is not to be captivated by physicality and carnal desires; instead, they should fear only God and no one else, never bow to this or that person like beggars, but bow only when necessary – namely, in the presence of God.

While this is the meaning of giving free will its due, it is the only way for real freedom. Only people who get rid of negative feelings like greed and envy, worldly expectations and fears are the ones who attain inner peace and relief. Since they are ready to leave this world as they came, they do not bend to any worldly power.

Is freedom in an absolute sense possible?

Some understand freedom as absolute liberty without any restrictions or conditions whatsoever. However, such liberty has never existed anywhere in the world to date. Neither in capitalist systems nor in liberal or communist ones, have people lived as they wished with unrestrained liberty. All systems sanctioned some rules to restrain freedom. For example, although communist systems broadened the limits of what is permissible and came up with an understanding alluring to passing fancies and desires, when it came to fidelity to the system, they acted strictly and tyrannically. They deprived people of their property rights, they killed the freedom for personal enterprise, and banned many actions that contradicted human nature and reason.

Likewise, although some states in our time have given much freedom to their citizens, they never allow any ideas that contradict the official ideology. They bring certain limitations regarding what they term as freedom of thought and conscience: they impose heavy sanctions when certain ideas that disagree with their worldview are voiced. No matter how much they refer to freedom, they cannot forbear the slightest degree of opposition to their own system.

A society’s general welfare and harmonious continuity necessitate adopting certain disciplines. If freedom is perceived and practiced as unlimited satisfaction of all desires and fancies, then this will cause corruption of lineages, breaking up of families, and degeneration of society. Likewise, although “freedom” might seem to allow it, we cannot approve of acts like profanity against the sacred, verbal abuse against religion, and making fun of the nation’s values, for allowing these will cause all moral values to be ruined. It is similarly not possible to accept as lawful, acting against the country or nation under the name of freedom, for in such a case the concepts of nation and country will lose importance, and it will become difficult for society members to co-exist.

On account of all these reasons, almost all legal systems have passed laws to provide shelter for the essential rights of religion, life, lineage, property, and reason; they imposed heavy sanctions against any crimes posing a threat to these. Namely, all states felt the need to draw a frame for freedom through certain laws and regulations. In fact, even while describing freedom, it is pointed out that your freedom ends where the limits of others’ freedom begins. In other words, although all citizens own certain rights and freedoms, they extend to the limits where others’ rights and freedoms begin. If we take the issue from a believer’s perspective, we can express this fact that God and faith too have some rights upon the individual, and they set certain limits for them.

In this respect, the notion of unrestrained freedom does not exist even among animals. They have certain limitations and boundaries, and there are consequences when they are violated.

Animals lead their life with astonishing solidarity and mutual assistance. Take penguins in the Antarctic: we feel dizzy before their system. Had people been able to establish such a system among themselves, all of us would live in peace.

God instilled certain rules in the brains of animals to let them live in an orderly fashion. However, humans possess reason and free will. We can even say that these are the most essential and indispensable human qualities. A human is neither a pile of wood, nor a sunflower stem. In this respect, for the sake of being able to live with others in an orderly and harmonious fashion, a person is supposed to comply with certain rules by means of reason and willpower. This is very important in terms of giving free will its due.

By giving willpower its due, humans will not only live harmoniously together but will even surpass angels. The noble Prophet Muhammad, peace be upon him, who used his free will to the best of his capacity, left the archangel Gabriel behind during his journey on the night of Ascension. Therefore, things like bidding for Paradise and being blessed with the honor of seeing God all depend on using one’s free will properly. On this path it might be necessary to sacrifice some aspects of freedom and to accept certain disciplines by means of free will.

Freedom is a great blessing God bestowed on people. If some people have lost such a divine blessing on account of their neglect and laziness, namely if they failed to retain their freedom, they will be held responsible before God. Furthermore, if they are not aware of being dominated by other ideologies, and not even endeavoring to be saved from this by refusing to regain certain opportunities they have lost, then they are not only betraying their freedom, but also their faith.

In this respect, appreciating the value of the freedom God granted us, upholding it and using it in the right way, are very important. In this respect, every nation needs to know well their era, have plans and projects for the future, and take promising steps as much as their cognition and circumstances allow.

Free thinking and science

Scientific thought has been shaped in the last few centuries by ideas based on positivism, materialism, and naturalism.

Scientific terminology has developed so extensively with these ideas that we are not able to think differently. And with these ideas we cannot reach the truth about our lives. For this reason, it is necessary for believing scientists to re-adopt free thinking as a principle and revise all their scientific conclusions. While doing this, they must be freed from attachment to the status quo and question everything, for it is not possible to establish something new without questioning. To this end, we need to consider that there is a possibility of being mistaken—be it a slight one—about the data we find before us. For example, a doctor specializing in medicine should be able to re-evaluate everything he or she has learned and re-test whether these are correct or not.

This surely is not an easy endeavor; it demands a very serious love for knowledge, research, and truth. Furthermore, it requires being able to dedicate a lifetime to this cause, to undertake very serious troubles and make serious sacrifices. If an industrial revolution happened in the West and serious distances were covered in science and technology, it happened thanks to the people who dedicated their lives to this issue. Some dedicated their lives to studying animal life, some to discovering the secret of historical relics, and some to decoding the tongue of natural phenomena. However, these studies of theirs ended up with materialism and naturalism. It is necessary to overcome this present situation and relate every truth about sciences to the One beyond existence and things. Like unweaving a sweater and re-weaving it with a new pattern, everything must be de-constructed and then re-constructed. While doing this we might sometimes be correct and sometimes err; we might take certain issues further than their present state and walk along with others at certain issues, and we even refer to their help.

However, these are not things to be realized by ordinary people. They require very serious resoluteness. But without such a struggle, it is not possible to be freed from dualism and to eliminate the contradiction between science and religion. Actually, while the origin of the Qur’an is Divine Speech, the Universe is similarly another divine book to be studied, as originated by His power and will. Given that these two books come from the same origin, it is not possible for there to be any contradiction between them.

Pursuing science under domination is no less painful than living under the rule of others’ domination. Merely quoting others but not being able to coming up with any new and original ideas should only be the growls of lowly souls surrendered to domination. Here I am saying like the poet Mehmed Akif did, “I have lived free and do live free for eternity/Who is to dare bring me under chains, I surprise, so crazy!” Actually every believer must possess this honor. They must look at their glorious past, turn to their spiritual roots, and then consider the present wretched condition and ask themselves whether or not it is shameful. Afterwards, they must absolutely set about being saved from these shames by building up their own world.

As souls under domination will not be able to realize such a revival, there is the absolute need for free thoughts. Actually, freedom begins in thinking. It is not possible to talk about freedom concerning people whose thoughts are dominated others.

We all may appreciate the difference between the positive impact made by a smile of pearly-white teeth and the repulsion triggered by yellowed and blackened rotten teeth, but the health issues run much deeper: as our medical knowledge grows, we are discovering that many diseases originate from dental cavities where microbes teem and nest, causing inflammations in many organs and tissues, most notably in the heart, kidneys, and joints.

The use of herbal sticks for cleaning teeth dates back to around 3500 BC, the time of the Babylonians. In several works of Ancient Greek and Roman literature, chewable sticks to aid dental and mouth hygiene are mentioned [1]. Hippocrates (355 BC) advises rubbing a ball of cotton wrapped around a stick and dipped in honey on teeth, to maintain dental hygiene, whereas Romans used pastes obtained from gumwood [2]. Dental hygiene is coming throughout history.

Arabs utilized the miswak for many years [3]. The Japanese used wooden sticks called “koyoji” and Jews used wooden sticks called “kesam.” In the 1920s, in some rural areas across the United States, a stick of blood-twig was used for rubbing on the teeth [3]. And according to a Chinese encyclopedia published in the seventeenth century, the first-ever toothbrush was made in China, in 1498.

Prophet Muhammad, peace be upon him, warned those of his Companions who visited him with bad teeth about the need for dental hygiene (Ahmad ibn Hanbal, Musnad 1/214):

“I oft reiterated my recommendations to you about the miswak.” (Bukhari, Jum’a 8; Nasai, Taharah 5; Ahmad ibn Hanbal, Musnad 3/143; Darimi, Wudhu’ 18)

“(The Archangel) Gabriel counseled me to use the miswak so much that I thought a verse might be revealed about the miswak to decree its use as obligatory for all.” (Ibn Majah)

Obviously he assigned the utmost importance to dental hygiene. It should be noted here that the Araq tree (Salvadora persica) from which the miswaq is obtained has features that are not present in other trees, and the Prophet particularly specified using the roots of that tree as the miswak.

Research has been conducted to discover the scientific and modern medicinal effects of the miswak, which has been used by Muslims in adherence to the Prophet’s practice. In 2010, a Ph.D. study at Karolinka Institute, Sweden, provided a significant message about its effectiveness [4] (Picture 1).

The Araq tree, which is used as the miswak across a geography spanning from Africa to the far east, is a short tree or bush with a slanted trunk, and it is easy to chew its spongy roots, parts of which generally expand and soften when dipped in water (Picture 2).

The roots of the Araq tree are washed to remove the soil, and approximately 1 cm from the tip of the root stick is peeled to be used as the toothbrush. The stick is pummeled or chewed until the fibers become softer (Picture 3). Fresh and soft miswak are preferable: If the miswak is dry, it is advised to dip it in freshwater for 24 hours before use. It is better to peel frequently, so the tip is renewed. The most practical advice is to use the peeled tip until it loses its tang and fragrance, because the fragrant components indicate the beneficial effect of the miswak. According to a study, using the same tip for more than 24 hours lowers its cytotoxic ability to get rid of microbes.

The practice of using miswak in the Muslim World is widespread in Asia, Africa, and some regions in the Middle East. As many Muslims opt for miswak use to maintain a practice of the Prophet, the World Health Organization (WHO) also advises and encourages the use of miswak as an effective dental hygiene tool along with the conventional toothbrush. The miswak is easy to use and effective; it also has chemical properties that help control dental plaque. Based on the basic information we have about the miswak, we can easily say that deeper research is needed for its different components, like its fibers, essence, and essential oils.

Antibacterial effects of the miswak

The antibacterial activities of the essences obtained by crushing different roots of the miswak have been analyzed by microbiological techniques. It was discovered that the miswak essence has a very strong antibacterial effect, predominantly against Gram-negative bacteria, including mouth-cavity microbes like Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Two additional studies conducted on five different types of bacteria i.e. Streptococcus mutans, S. faecalis, S. aureus, Haemophilus influenzae, Salmonella enterica, and Candida albicans, and a type of fungus [5, 6, 7, 8] revealed that the miswak essence stops the reproduction of micro-organisms, has a lower effect on Lactobacillus acidophilus, is active against Herpes simplex virus which causes blistered lesions, and suppresses acid production.

The essential oil obtained from miswak essence includes 70% benzyl isothiocyanate, 9.4% limonene, 8.7% I-pinene and 2.55% flavonoid. As the miswak’s main antibacterial component, benzyl isothiocyanate kills bacteria by forming protrusions on their cell membranes. The volatile nature of this substance may open doors to new practices requiring antibacterial treatment. It has been proven that fresh miswak is effective at preventing the formation of dental plaque and gum inflammation, and it has also been acknowledged that it may play a potential role in preventing periodontal diseases.

The miswak essence hinders acidic (pH) conditions causing tartar and dental plaque, leads to a long-term increase of pH in the mouth, stimulates saliva flow in the parotid glands (located in front of both ears), and prevents tartar formation.

It is necessary to conduct further lab and clinical research to augment the positive results shown so far about the effects of the miswak against the inflammation of the palate and gums, as well as its antiviral and antifungal activities. Some research has additionally suggested that the miswak has antioxidant, analgesic, and anti-inflammatory effects. It is claimed that potassium chloride, salvadourea (a urea derivative), alkaloids, and oleic and linoleic acids in the miswak sap increase the viscosity of saliva, helps it to soak into hard-to-reach corners in the mouth, and contributes to overall dental hygiene. It is reported that a substance named Xylitol in the miswak essence suppresses acid production and the reproduction of mutant streptococci [9, 10].

An interesting substance in the miswak oil

Benzyl-isothiocyanates are effective molecules in the defense systems of several plants such as cabbage, watercress, and broccoli. Secreted after damage to plant tissues, benzyl isothiocyanate forms a protective antibacterial layer on the damaged part of the plant. While dental plaque and tartar are mechanically removed by rubbing the miswak on teeth, this action also helps the substance secreted from the miswak reach deeper parts of the oral cavity. It is especially proven that benzyl isothiocyanates are strongly effective as bactericide on Gram-negative bacteria and have minimal effect on Gram-positives.

Lab tests conducted on animals indicate that these components also have anti-carcinogenic activity, and people who get isothiocyanates by nutrition have a lower risk of cancer. It is fascinating that the miswak, too, has the same substance.

While introducing a new set of ethical principles, Prophet Muhammad, peace be upon him, revoked some customs and habits inherent to the pagan culture before Islam (Age of Ignorance) and kept others. Using miswak was a practice among the Arabs in the region; the Prophet encouraged its use and emphasized its benefits. Eventually, Muslims have adopted it as not only a habitual practice, but also as a healthy spiritual activity and are keeping the memory of the Prophet alive.

She stood at the edge of the abyss, the blinding darkness engulfing her, enticing her. It would be easy to let go, to wither away and join him. Her arms felt numb, and her powerful legs were weak. Violent tremors traveled up and down her body. A small compelling hand, wet with tears, tugged on her arm. “What will we do now?” a quavering voice whispered. She opened her eyes. The sky was a cerulean blue, and the blazing sun was beating on her torn straw hat, casting a slender shadow on the spring green rice fields. Her rapid heart was calmed by a wind that caressed her cheek. To her dead husband, to her children, to Vietnam, she dropped the condolence letter, and with her feet firmly planted on the ground, said, “We will live.”

To say it was easy is an understatement. Raising five kids as a single mother, in a country where women are expected to be docile, seemed infeasible. “I was taught at a young age that men were the head of the household, they were the heroes of the family,” Diep Ngo, aged 80, recalls sadly, her eyes distant. “I felt helpless. My brothers were charting new paths, while I was still, unable to move.” With a suppressed sob, Ngo recounts that at the twilight hour, she would drown with dark thoughts, but every morning when the sun rose, they would be vanquished. The roosters were the reveille that awakened her slumber, her empty stomach was the battle cry, and the last words of hope from her departed beloved, the mantra that carried her on. 

The war took its toll on the civilians of Vietnam; it was a disease that plagued families with deaths and injuries. Young girls were jailbirds, kept busy looking after their younger siblings, torn rags their striped attire and restrictions the bars of their prison. Dreams were locked away, replaced by the basic needs crucial to survival. Even so, when asked if she would take part in the war that claimed her husband, Ngo, her mouth in a straight line and her eyes ablaze, adamantly nodded. Raising both arms until her fists were level with her head, she mustered a grimace. Her nose crinkled and teeth bared, but her eyes sparkled with humor. “Do you think anyone would’ve thought twice about taking me on?”

Scraping bits and pieces of broken memories from her childhood, Ngo recalls that the only freedom she truly had was that from the pressures of education. “I never did well in school. Women were not expected to accomplish anything, so it was highly unusual for a women to achieve higher education.” Now, it seems clear that this supposed freedom transformed itself into another burden upon her shoulders, for she had to take on menial tasks when drafted into the position of “man.” For the first time in her life, she left the cage built by the patriarchal society and refused wealthy suitors. “They were bloated with pride… I would never submit to any man like that.” Ngo was ridiculed by her neighbors as a result, but she felt a strange sensation, absent from her life ever since the fateful, disappointed sigh that accompanied the doctor declaring her gender 80 years ago: the jewel of independence.

“As their father was gone, I had to step into the role of the provider. Oh, what a burden it was, but the power and purpose it gave me fueled the sleepless nights.”

Before the age of 30, her long, black hair turned a platinum gray, and impending wrinkles scarred her face as the war robbed her of youth. A moment to weep or reconcile with memories of loved ones was lost in the present.

“Losing my husband was truly hard, but myself, and other women of Vietnam, had to choke back grief and look to the future,” she remarked. Leaving the house militarily before the sun rose and coming back well after the crescent moon silently loomed in the sky, the only thing Ngo regrets is not spending as much time with her children. But, what she had to do was necessary, as every day was a battle. Even so, how could she explain to them the rough calluses on her hands, which toiled tirelessly, tending the infested wounds left after the hungry bullets pierced the heart of Vietnam? How could she explain yet another outline of a large palm on her red cheek, this time from an angry customer, unsatisfied by the knee-length trousers she had spent all night mending?

Through it all, she remained an eternal warrior, whose struggles rivaled those of men fighting raging wars. Diep Ngo battled gender inequality and injustice, all while leading her family through desperate times. An old poem by Xuân Diệu filled her thoughts as America, the land of rebirth and opportunities, slowly emerged on the horizon: “Your feet have hardly tread round this way… Open your arms to clasp the spring, then from your hand let there be light” (translated by Thomas D. Le). And for the first time since her husband’s death, she welcomed the moist tears, for the valiant soldier’s burden had been lifted. Her dauntless mission was complete. 

I’m forever grateful for her valiant decision to bypass social stereotypes and become a sort-of soldier, leading her family to survival, to new opportunities, to an education, to happiness, to America. It’s a natural, humane feeling that is respectful of the wisdom, the strength, and the sacrifices of the old. Every evening, after the tiring cycle of school, I retreat back into my place of comfort: my grandmother’s arms, and for the past 17 years, her past life was but a false, beautiful painting, rid of pain and hardships and suffering. That one night, under a blanket of softly twinkling stars, I retraced her hands, touching them, caressing them, tracing her old, calloused, scarred fingers and her bulging veins, to finally realize the truth: that there was so much I didn’t know about my hero.

The parable of those who take to them other than God for guardians (to entrust their affairs to) is like a spider: it has made for itself a house, and surely the frailest of houses is the spider’s house. If only they knew this! (Qur’an, 29:41)

A prehistoric Greek fairytale says a young girl named Arachne was a superb spinner and knitted the most gorgeous cloth. She dared the goddess Athena to a competition. When Athena saw Arachne’s stunning work, she ripped the cloth and hit the young girl. Disgraced, Arachne committed suicide by hanging herself. Athena regretted and transformed Arachne into a spider, so that she could whirl repeatedly and endlessly. Arachnida is the scientific name for spiders. It comes from the young girl in the famous Greek fairytale.

Although usually feared and disliked by people, spiders in fact make life easy for us by feeding on mosquitoes, flies, and locusts, thus saving our crops and eliminate the need for man-made insecticides which pose environmental problems. Besides, spiders are much less dangerous than people think they are; most spiders are keen to avoid interaction with people and will bite only when wounded or scared. Even poisonous spiders are rarely as dangerous as popular myths would have us believe: though black widows are poisonous, and their bites painful, they rarely kill people. If handled properly and quickly the adverse consequences of a black widow’s bite typically diminish in a few hours, and, after a couple of days’ rest or cessation of activities, the victim will fully recuperate [1].

There are countless features of spiders. But their silk is exceptionally unique and this article covers its various aspects.

Spider silk

Biomaterials, having developed over millions of years, frequently surpass man-made substances in their properties. Spider silk is an exceptionally stringy biomaterial which is made almost completely of substantial proteins. Silk fibers have stretchy powers similar to steel and some silks are practically as elastic as rubber on a weight-to-weight basis. In uniting these two properties, silks disclose a hardiness that is two to three times that of artificial fibers like Nylon or Kevlar. In addition, spider silk is also antimicrobial, hypoallergenic, and completely biodegradable [2].

The power of spider silk, so fragile in manifestation, is astonishingly great. A filament can be outstretched as much as one half its normal length before breaking, and has a tensile strength exceeded only by fused quartz fibers. Fine fibers are sturdier than others, the power to some degree depending on the velocity with which they are pulled out of the spider’s body. The higher the speed, the superior the strength.

Most of the silken fibers are not single fibers but are made up of two or more strings. A thread may be as fine as a millionth of an inch in width but, frequently, it is ten or twenty times as dense, and the assemblage of these threads unsurprisingly creates larger threads of a diversity of thicknesses. Furthermore, some threads are gluey whereas others are not.

Scientific research demonstrates that a single thread of spider silk, thick as a pencil, could stop a 747 Jumbo Jet in flight, and that on an equivalent footing, the spider’s silk is stronger than steel, per unit weight. It has been shown that the dragline silk of the golden orb spider is one of the planet’s hardest threads.

Spiders employ silk for webs, but also for trap lines, draglines, ballooning lines, for egg pouches and nursery nets, for compartments in which to sleep through winter or to copulate, and for entrapping and wrapping their victims. Silk for all these objectives is not accomplished with one kind of gland; there are at least seven distinct kinds. A few distinctive spiders have as many as six kinds and probably have more than six hundred independent glands; others have fewer than this [1].

Mechanism behind the formation of spider silk

A batch of scientists headed by researchers from the RIKEN Center for Sustainable Resource Science (CSRS) have scrutinized spider silk and discovered that a formerly undiscovered organizational constituent is critical to how the proteins form into the beta-sheet conformation that gives the silk its extraordinary power [3]. If humans can cultivate equivalents to spider silk, they could be applied in industrial and medical applications. It is well-known that the beta-sheets in spider silk are significant to its strength, but how the sheets are created is scantily comprehended, making it difficult to produce synthetic variations. It is hard to comprehend the process: the silk is originally produced as soluble proteins, which very swiftly crystalize into a solid form.

To explain this, the CSRS scientists obtained silk proteins using genetically altered bacteria that can generate silk from a golden orb-web spider (Nephila clavipes) and then executed multifaceted examinations of the soluble proteins. They discovered that the reiterating area is comprised of two designs – unsystematic spirals and a design called polyproline type II helix. Their investigations confirmed that the polyproline type II helix is critical for the creation of the stiff construction, which can then be rapidly converted into beta-sheets, letting the silk be swiftly intertwined. Fascinatingly, it was discovered that pH – which is supposed to be significant for the molecular exchanges of the N- and C- terminus areas – does not play a significant role of the foldup of the recurring areas, and that it is rather the elimination of water and mechanistic forces through the silk gland. 

According to Keiji Numata, who is a project leader of JST ImPACT and led the research group, “Spider silk is a wonderful material, as it is extremely tough but does not contain harmful substances and is readily biodegradable, so it does not exert any harmful load on the environment” [4]. Numata hopes that this discovery may lead to the production of artificial silk that will prove useful for society.

Analysis of silk

The silk itself is a material identified as a “scleroprotein.” When created in the glands it is a fluid; only when dragged outside the body does it solidify into thread. Once it was believed that contact with air produced the toughening, but it currently looks that the drawing-out activity alone is accountable for the change.

To carry out the exertion done by the glands, a spider is armed with spinnerets, usually six in number. These are as accommodating as fingers; they can be prolonged, compacted, and overall be applied like human hands. In the “spinning field,” where the spinnerets are congregated, single threads are joined into numerous compound threads, and some of the dehydrated threads may be covered with a gluey substance. Thus, a completed thread may be thin or thick, dry or sticky. It may also have the look of a bead-trimmed necklace. For the last kind, the spider spins rather unhurriedly and, drawing out the gluey thread, lets it go with a jolt. The liquid thus is organized in beads spread out lengthwise across the completed line.

The strand known as the dragline may be understood as a spider’s “life line” because it performs as a lifeguard in all kinds of situations. The dragline goes along with the spider, no matter where or how far it journeys, winding out from spinnerets at the back of the body. It forms a portion of the building of webs, it grips its tiny builder firmly in problematic places, and it helps in absconding from adversaries. When a spider is inactive in a web, the dragline enables a rapid descent and escape. It allows energetic chasing spiders to jump from buildings, cliffs, or any tall position with absolute security. [1]  

Benefits of spider silk to us

The silk of the silkworm could be very profitable and marketable. There are, however, challenges. One is the changing thickness of a spider’s strand; the other is that it doesn’t well endure the interweaving process. Housing and feeding large numbers of silkworms is not difficult. But housing and feeding large numbers of spiders? There are enormous difficulties.

Native inhabitants of New Guinea have used spider silk in a variety of conditions. They make fishing nets, traps, and such objects as bags, headdresses that will keep away rain, and caps. These are not formed from single threads but from tangled, warped threads. The aboriginals of North Queensland, Australia, look to spiders for their angling supplies.

Spider silk has been valuable to the manufacturers of such complex instruments as astronomical telescopes, guns, and engineers’ levels. The threads, being exceedingly fine but nonetheless robust, are outstanding for sighting marks. Throughout the Second World War, there was a significant demand for spider thread for surveying and laboratory instruments. Black widow spiders were utilized for the manufacture of this silk.

One drawback to the use of spider silk in industry is that it might slump in a moist environment. To overcome this problem, strands of platinum or etching on glass plates take its place in such instruments as periscopes and bombsights. [1]

Spider’s silk also might have healing properties. Due to its antibacterial properties and because the silk is abundant in vitamin K, it may be efficient at clotting blood. Because of the problems in obtaining and handling extensive amounts of spider silk, the largest known piece of cloth made of spider silk is an 11 by 4-foot (3.4 by 1.2 m) fabric made in Madagascar in 2009. Eighty-two persons labored for a period of four years to gather over one million golden orb spiders and extract silk from them. [5]  

Applications of spider silk

As mentioned, human beings have been using spider silk for thousands of years.

The manufacture of contemporary synthetic super-fibers such as Kevlar (bulletproof material) includes petrochemicals, which adds to pollution. Kevlar is also strained from concentrated sulphuric acid. In comparison, the manufacture of spider silk is totally ecologically sustainable.  It is created by spiders at ambient temperature and pressure and is strained from water.  Furthermore, silk is totally biodegradable. If the manufacture of spider silk ever becomes industrially practical, it could be a substitute for Kevlar and be used to create a varied extent of articles such as: bulletproof vests, wear-resistant lightweight clothing, ropes, nets, seat belts, parachutes, rust-free boards on motor vehicles or boats, biodegradable bottles, bandages, surgical thread, artificial tendons or ligaments, and backings for weak blood vessels. [6] 

Synthetic spider silk [5]

Duplicating the multifaceted settings needed to make threads that are similar to spider silk has been difficult to both research and manufacture. Through genetic engineering, Escherichia coli bacteria, yeasts, plants, silkworms, and animals have been utilized to produce spider silk proteins. Yet, these synthetic threads have diverse, simpler features than those of a spider. Manmade spider silks have lesser and unsophisticated proteins than natural dragline silk, and have subsequently half the diameter, strength, and flexibility.

One tactic is to remove the spider silk gene and utilize additional life forms to generate the spider silk. Canadian biotechnology company Nexia effectively produced spider silk protein in transgenic goats that passed the gene for it; the milk made by the goats comprised noteworthy amounts of the protein: 1-2 grams of silk proteins per liter of milk. To make spider silk, Nexia utilized damp whirling and pressed the silk protein across minor extrusion cavities in order to mimic the performance of the spinneret, but this process was not adequate to duplicate the sturdier characteristics of innate spider silk.

In March 2010, investigators from the Korea Advanced Institute of Science and Technology was able to produce spider silk by means of the bacteria E. coli, altered with definite genes of the spider Nephila clavipes. This tactic removes the necessity of milking spiders.

It should be noted that the manufacture of spider silk is not easy and there are intrinsic difficulties. First of all, spiders cannot be cultivated like silkworms since they are flesh-eaters and will merely eat each other if in proximity to each other. The silk produced is very slight, so 400 spiders would be required to make only one square yard of cloth. The other problem is, silk also toughens when subjected to air, which makes working with it problematic.

A different tactic is to study how spiders whirl silk and then replicate this process to make artificial spider silk. The silk itself would also have to be synthetically produced. Chemical production of spider silk is not feasible at present due to the absence of information about the makeup of silk. Randolph V. Lewis, Professor of Molecular Biology at the University of Wyoming in Laramie, has introduced silk genes into Escherichia coli bacteria so that the recurring sections of spidroin 1 and spidroin 2 efficaciously come to form. Others theorize about the likely gene introduction into fungi and soya plants. It may also be possible to modify the silk genes for precise intentions. 

Why a spider’s house is the frailest of houses

Spider silk is stronger than steel, but the Qur’an (29:41) states that the flimsiest of houses is the spider’s house. The per unit weight of the dragline silk of the golden orb spider is one of the world’s hardest fibers. Webs are combinations of many kinds of spider silk, all able to be produced by the same spider. The web radials are strong, but the somewhat feebler circumferential (quasi-circular concentric) fibers are flexible and gluey to absorb the energy of a flying insect and hold it in place. The strongest of all is the fiber, which the spider uses for transport, the dragline silk. In summary, the spider fabricates both sturdy as well as feeble fibers and the web it weaves to catch flying insects is weaker; this may be the reason why it is referred to in the Qur’an as the “frailest” of houses.

Conclusions

Scientists are foreseeing many potential uses for biosilk. Textile usages are noticeable one. The flexibility and potency of prevailing merchandises such as spandex and nylon have to be improved. Since it is lightweight, hardy and flexible, biosilk may also have uses in satellites and aircraft. More prominently, the new group of progressive things that spider silk investigation may cause has the prospective to alter our lives in innumerable manners that we can barely imagine. More than 72 years have passed since the inventions of Wallace and Carothers that gave the world nylon that led us into the age of polymers. Artificial spider silk may help produce super-performing clothes of the future. Earthquake resistant suspension bridges hung from cables of synthetic spider silk fibers may someday be a reality. [1]

Ma’rifa is a special knowledge that is acquired through reflective thought, sincere endeavor, using one’s conscience and inquiring into one’s inner world. It is different from (scientific) knowledge (‘ilm). (Scientific) knowledge is acquisition reached through study, investigation, analysis, and synthesis, while ma’rifa is the substance of knowledge attained through reflection, intuition, and inner perception. The opposite of (scientific) knowledge is ignorance, while the opposite of ma’rifa is denial.

Knowledge means comprehending or encompassing something thoroughly, while ma‘rifa means familiarity with or recognition of something—that something may be the Divine Being—in some of its aspects. For this reason, the One of Unity is called the All-Knowing (‘Alim), but He has never been called the One having familiarity with something (‘Arif). In addition, the exacting scholars of truth view ma‘rifa, which also means information, talent, and skill, as the culture acquired by conscience or one’s conscious nature. It has other meanings such as the ability to feel something with the spiritual faculty that humanity has been endowed with, the image of something known in the mind, and the knowledge kept in the memory which gains strength through repetition. From another perspective, it is consciousness, perception, and sufficient information which helps distinguish one thing from another. Ma‘rifa can be summed up as having concise knowledge about something or someone through their acts or works and attributes—knowledge which can be developed and detailed.

In order that one can be among those who have knowledge of God and who are regarded by God as being one of such people, one should have certain theoretical knowledge about God and the ways that lead to Him, recognizing the obstacles on the way, and knowing how to overcome these obstacles. One should also have enough willpower to apply what one knows. One who has true knowledge of God is a perfect human being who knows the Unique One, Who is the Eternally Besought, with His Acts, Names and Attributes, and is a person in whose everyday life this knowledge shows itself. He or she is also one who always keeps the heart purified and pursues sincerity and purity of intention, who can remain free of negative or evil moral qualities as far as possible, overcoming whatever dark emerges from the spirit and threatens to darken one’s horizon, and thereby demonstrating loyalty to the All-Watchful Guardian. Such a one can bear everything that befalls on God’s way to obtain His approval, and invites others to the way of the Prophets, which shows itself through God’s confirmation in every step, and whose lights he or she always feels with pleasure.

There is another approach to ma‘rifa that ma‘rifa is the ability to perceive something as exactly what it is in itself, in its true nature and identity, and based on the thing itself. According to this approach, knowledge of God is knowing the Divine Being with His Essential and Affirmative Attributes beyond all conceptions of modality. This is different from comprehending, perceiving and establishing other things, and is based on perception and knowing by conscience. This knowledge and perception should not be confused with modern intuitionism. The Divine Being is beyond all concepts and cannot be comprehended, perceived or scientifically known, although a certain knowledge or familiarity can be acquired of Him through His Acts, Names and Attributes.

The acknowledgment that The inability to perceive Him is the true perception, excellently expresses the inability of anything limited to perceive Him and the imperceptibility of the One Who is Infinite. The same meaning is exquisitely expressed in the saying, We have not been able to know You as knowing You requires, O the One Known.

It is only God Whose existence is absolute, and the greatest truth is acknowledging His Existence and Oneness. The first step in acquiring knowledge of Him is the attainment of belief, being a Muslim, and excellence—worshipping Him as if seeing Him. In realizing such a blessed aim, one should continue one’s traveling to the True Source of all gifts and blessings without turning to anything else as a source. One should be able to feel a new joy of reunion in every gift and blessing with which one is favored, and as the final point, gain familiarity with the mysteries of His Names and Attributes, and, if possible, of His Being.

This consideration is expressed as follows in Lutfiya by Wahbi:

Try your hardest and be one who has ma’rifa of Him,
One favored with knowledge of Him!
For the All-Loving declared, “so that I may be known;” [1]
Knowing God is the ultimate cause for the creation of the two worlds;
and knowing God is the adornment of humanity.
Those devoid of knowledge of Him are low in rank.
Knowing Him is a spiritual kingdom,
and Knowing Him is a Divine gift and blessing.
….
When you, O moving spirit, receive this gift and blessing;
the two worlds will be yours.

The following words, which are narrated in books concerning Sufism as a hadith qudsi—a saying, the meaning of which is from God and the wording of which was inspired in the Messenger—are the gist or kernel of all explanations concerning knowledge of God:

O humankind! One who knows his self also knows Me; one who knows Me seeks Me, and one who seeks Me certainly finds Me. One who finds Me attains all his aspirations and expectations, and prefers none over Me. O humankind! Be humble that you can have knowledge of Me; accustom yourself to hunger so that you can see Me; be sincere in your devotion to Me so that you can reach Me. O humankind! I am the Lord; one who knows his self also knows Me; one who renounces his self finds Me. In order to know Me, renounce your own self. A heart which has not flourished and been perfected through knowledge of Me is blind.

Knowledge of God sometimes becomes a source of wonder and astonishment for initiates, as has been said, “One who knows the Ultimate Truth becomes dumbfounded and tongue-tied.” But it sometimes becomes a means of expression for them, as has been said, “One who knows the Ultimate Truth finds his voice.” The voice finds its overflowing expression in one’s excitement and speech and echoes in many other ears. Although opposites, both the saying of Muhammad Parisa, [2] “There is none who knows the Divine Being other than Himself,” and the saying, “I know none else save God,” are true each in its own context.

There is none other than Him who has a true, substantial existence, and there are no true acts other than those done by Him. Other beings have a relative existence when compared with Him, and other acts, which take place in the cycle of causality, is of a relative nature. For this reason, knowledge of God is when an initiate melts away in the light of the Ultimate Truth and gains a new, “true” existence. This may be viewed as self-annihilation in God and subsistence by Him. I think the author of al-Minhaj stresses this fact in these verses:

If you can see with the lights of certainty,
then do not see one who knows and the One Known differently.

Fuduli [3] expresses this depth of knowledge of God as follows:

One who knows God is not one who knows
the wisdom of the world with what is in it.
One who knows God is he who does not know
what the world is with what is in it.

Sufis have made other descriptions concerning knowledge of God. According to these descriptions, knowledge of God is knowing the truths of the Divine Names and Attributes, grasping the phenomenon of the manifestations in existence and the discovery of the existential mystery, deeply perceiving the truth of existence with its originality and shadows, and understanding and representing in life the truth of religion according to the Will of the All-Desired One, Who is the final goal of those who set out to reach Him. Each of these descriptions requires a voluminous work to explain and is therefore beyond the scope of this study. We will only cite here some verses from Diyaiya (“The Book of Light”) which point to some dimensions of the subject matter:

The third chapter is about knowledge of God, O valiant young one;
to describe it the wheel of speech is unable to work.
….
There is no scribe nor a pen to write about it;
one cannot get his tongue around it to express it.
….
The mirror of reason is veiled from understanding it;
the ability of perception has nothing to say in it.
Only the bird of imagination can fly toward it;
there is no example that we can coin to explain it.
….
Here the gift comes only from God;
this is a light-diffusing, sacred rank.
….
The whole of creation is immersed in this realm,
which is more spacious than all the worlds.
….
There is no true existent save He Who is the One,
perceiving this is the real vision.
Do not interpret this vision in another way, or else,
it will mean unbelief and heresy, O one with body of light.
It is not the eyes in the head which have this vision;
The All-Loving One is all-free from vision by these eyes.
The innermost faculty—secret—discerns this truth,
when you find this faculty in you, you can understand it.
Human scientific knowledge and perception have nothing to say;
the merit is in wonder and helplessness in this field.
Perception of one’s helplessness is perception of the Ultimate Truth;
listen to what Abu Bakr, the truthful one, says concerning it. [4]

The rank of knowledge of God (ma‘rifa) is a rank of wonder, utter astonishment, and awe. It is possible to see this in almost all the reflections of the scholars of Sufism on knowledge of God. Some of them see it in direct proportion to the excess of the feeling of awe and have concluded that the deeper one is in knowledge of God, the deeper one’s feeling of awe is. Others regard knowledge of God as being the base of serenity and peacefulness and emphasize that inner peace and self-possession increase in proportion to the depth of knowledge of God. Still others consider knowledge of God as the heart’s attainment of friendship with God and the initiate’s following a way to nearness to God.

The approach of ash-Shibli opens new windows on the knowledge of God. According to him, it means that an initiate has an essential relation with none save God, making no complaints when burning with His love, is a sincere, obedient and faithful servant of God who avoids any claims of superiority, and one who worries about his or her end. A person with true knowledge of God and who has a strong connection with the sources of this knowledge, one who has taken refuge in the guidance of the spirit and meaning of Prophethood, and who has built sound relations with the truths that lie beyond human horizons, cannot feel any essential interest in transitory things nor does lower him or herself to feel attachment to others than the Lord. The Qur’an alludes to this highest point in (35:28), Of all His servants, only those possessed of true knowledge stand in awe of God, reminding the traveler of the relation between knowledge and awe or reverence of God. The greatest of those who have knowledge of God, upon him be peace and blessings, said concerning the same point: I am greater than you in knowledge of God, and more intense in fearing Him.[5]

In the books on Sufism, in which the intellect guided by Revelation is operative, and which contain numerous gems of wisdom concerning the “garment of piety” of those who have true knowledge of God, with Whom their hearts are deeply connected, we can find many gems concerning knowledge of God. The following are only a few of them:

• In the view of one favored with knowledge of God, the world with its material aspect becomes so small that it seems no greater than a cup.
• The souls that have gained profundity in knowledge of God expand to the extent that it is as if they have no
• Those who taste the pleasure of knowledge of God, which is regarded as the sweetest of all honey, pursue no other wealth than nearness to the Ultimate
• The richness of the honeycomb of knowledge of God in the heart is one of the most essential sources of love and An initiate burns with the zeal of reunion in proportion to how much this source overflows its banks, which he or she sees as the price of the favors received.

The following points which differentiate those who have a sound knowledge of God from others are important. The former have no selfish expectations from whatever good they do, never think of competition for either material or spiritual ranks nor feel jealous of anybody. They do not see themselves as being greater than anyone else, nor do they moan because of missed opportunities, anymore than they feel arrogant because of their accomplishments. Even if they were granted the kingdom of the Prophet Solomon, they would only seek God’s company, regarding it as futile to turn to other things. They feel no relation with beings other than the Almighty with respect to their worldly existence and corporeal selves, and know that one moment of God’s friendship is worth the entire world. They consider being with God among people as a victory that has been granted to their willpower, and see the Divine Will reflected in the face of their determination, recognizing the help of the Lord in the result of their endeavor, alongside many other instances of wisdom and God’s extraordinary gifts. They observe the manifestations of the Divine Oneness in the multiplicity of the creation, and thereby they grasp how a drop is transformed into an ocean, and a particle into the sun. They witness in their conscience how nothingness or non-existence is a fertile land, to be planted with existence and live drowned in ecstasies and intoxication.

Self-possession, steadfastness, seriousness, profundity, and resolution are the clearest and most important signs of perfect knowledge of God. Those who have this degree of knowledge live under the shower of the manifestations of God’s friendship and company. No sign of any flaws can be seen in their inner or outer world, nor is any laxity witnessed in their behaviors. They never show impertinence or conceit, even when favored with the most abundant gifts. On the contrary, they always act in a self-possessed manner, trying to lead a self-disciplined, spiritual life.

Obviously, everyone cannot have the same degree of knowledge of God. Some travel on the horizon of perceiving the Attributes essential to the Divine Being and the favors that accompany His Acts. They observe and avail themselves of His proofs that are found within themselves and in the outer world, with the result that their love of truth and their relation with the Greatest of Truths are witnessed in their manners. They travel between the Divine Acts, Names and Attributes and are thrilled with the different melodies of belief, knowledge of God, love, attraction and the feeling of being attracted by God to Himself. They feel in their conscience the reflections of the Divine Acts or operations in the universe and pursue more and more the pleasure entailed in observing ever new colors and aspects. This is a way bequeathed by the Prophets and it is a way that can be followed by everyone. One who travels along this way of objective truth travels toward the Ultimate Truth under the arches of His regard and compliments.

On this path there are others who feel all the dimensions in existence ending in one dimension, who feel that everything is annihilated in God. It is as if they have reached a point where the lights and manifestations of the Divine Being and Attributes come together from the perspective of humanity and annihilate their very being in the Divine Being, attaining a new existence with the Self-Subsistence of Him Who is the All-Knowing and the Ever-Existent.

While those belonging to the former group travel in the realm of the Divine Attributes and Qualities, others have already directed themselves to the Source of these Attributes and Qualities. Therefore, their observations and sensations are not aimed at either the Attributes exclusively in such a way as to veil the Being in their minds or spirits, nor at the Being exclusively in such a way as to suggest the denial of the Attributes. For this reason, such an approach has been regarded as the way of the perfected and most advanced, and the main path that is followed by those who travel to the greatest nearness to God.

The Book, the Sunna, reason, and the Divine system in creation and human primordial nature bear witness to the truth of this way along which God’s works of Art show themselves brightly. Initiates who have firmly established their feet on this path witness at every step that God witnesses His Existence and Oneness, and they cannot help but utter, God bears witness that surely there is no deity but He (3:18). They hear in their conscience the confirmations of angels and those possessed of knowledge as a reflection of God’s Own witnessing, and continue to utter: and the angels and those possessed of knowledge (also bear witness to the same truth) (3:18). Then, they see that all means and causes that are not essential to His Being having vanished, and they are able to be at perfect rest and to find perfect peace.

There are others who have such abundant knowledge of God that proofs of God are no longer needed in their world; all the things that witness Him are humbled in the face of their being in the Presence of the True Witness; all the means tremble with the shame of making distant whatever is near, and all the heralds are silent and busy with correcting the words that they have uttered. At this point, where everything is seen by the conscious nature as witnessing Him beyond all concepts of modality, the eyes are dazzled by the brightest manifestations of the “Divine Facial Light,” and all other identities save His are lost. Those who have reached this point see that the True Source of existence and knowledge surrounds everything from all sides, tasting the pleasure of perceiving every being’s perception of Him according to their level, and feeling that everything is annihilated in Him. They sense the way in which the manifestations of the Divine Names are combined with those of the Being, Attributes and Acts. The conscience is saved from any feeling of dependence on causality and reaches the horizon of Surely we belong to God (as His creatures and servants), and surely to Him we are bound to return (2:156). But this never means, as some have assumed, “absolute annihilation” or “union with God.”

Our Lord! Grant us from Your Presence a special mercy and arrange for us in our affairs what is right and for our good! And bestow blessings and peace on our master Muhammad, by whom the mysteries came to light and the lights shone brightly, and on his pure Family and Companions.

We woke at the thud, panicked.

My wife and I had been dozing in bed, squeezing the last seconds of sleep out of our pillows before the inevitable onslaught of little people. It’s something of a delicious defeat when you hear the door creak open and steps on the carpet. You know you’re trading something so precious to you (sleep) for someone so precious, who you just wish would be precious elsewhere. But then they’re all warm and soft and tousle-headed and snuggly and saying things like “daddy, can we have special cereal?” and poking their knees into your side and sitting on your face with a full diaper and sticking cold toes into your armpits.

This morning they didn’t get to do all those precious, horrible things to us because we woke up to the sound of something thwacking against our window. After shaking off the confusion (no, it’s not a child on the roof; they can’t reach the window), I recalled why I knew the sound. It was a bird. And from the sound, a pretty sizable one.

I said as much to my wife, as I tried to open my eyes but managed only a half-squint. She half-muttered sympathy, as if she cared deeply inside but couldn’t get past the early morning fog. I added that since it was a big bird, it probably got away a little dazed, no harm done. I tried to find her to give her a reassuring pat, but I was too drowsy and missed completely. I also couldn’t pry my eyelids open still; they ached a little, as if I hadn’t used them for a week instead of approximately six hours.

I’ve read that birds, reptiles, and some mammals have something called a nictitating membrane, a third eyelid that acts as a translucent shield when they are diving or flying. They can draw it horizontally across each eye to moisten and protect it. For instance, many birds use it when they are regurgitating food for their kids so they don’t get their eyes poked out by little beaks.

I think of things like this when I’m abruptly disturbed from sleep. Things like this, and demonic children’s songs that will not be exorcised for hours.

We turned over and buried ourselves in the blankets for three more minutes before the precious, horrible people came and got us.

Nadia was playing hopscotch out on the sidewalk later in the morning when she found the bird. Robins are always the first birds my children encounter and remember. It was easy for her to name the body she stumbled upon, one story below our window, and quite dead. We had a little flurry of don’t-touch-that’s and daddy-is-it-going-to-be-okay’s, and I managed to deposit it into a small terrarium for them to look at. Animals can die of diseases communicable to humans, but this one died upon impact, and it was still warm. So the kids and I examined it carefully.

It was larger than any bird I’d seen this close. The wings were tucked in beside its impossibly light body. Many of its bones were hollow, for ease of flight. The neck was at a weird angle, a wrong angle. The death in front of me was at a wrong angle. It always has been, but it just felt much more wrong suddenly, because it was also in front of my children. Blood speckled its beak, a dark decoration above the warm red tinges on its chest.

I realized that it was a young one, probably a teenager in robin years. Its feathers were perfect, straight and sleek, pinions just slightly larger and smaller on each side, forming beautiful strong wings. And the roses on the sides under the wings were just barely forming up into a speckled breast. It was about the size of an adult but without the experience, which is why it probably hit our window.

One eye was slightly open and looking like black jelly, like it would spill out of the socket as liquid if you tipped the bird over slightly. The other eye was closed. This teenage robin had eyelashes on the under-lid. It had whiskers. Its feet were curled and delicate.

It was too beautiful. It was too sad.

Nadia was watching me. She told me she was sorry that it died because she could see the sadness in my eyes; but I wasn’t really mourning after the bird. We touched its wings, feeling its perfect form beneath our fingers: the surreal softness, the preciousness of a young fleeting life snuffed out. Not a sparrow falls but that He sees it. God saw this.

Woodpeckers will close their nictitating membrane, then tighten it a millisecond before they hit the tree so that their eyeballs don’t fall out on impact. Perhaps we need similar shields.

Only a few days earlier we had discovered a young robin hopping around the pine tree down in the yard. We took pictures. The kids enjoyed watching it hop around. There was a hawk above, circling around, and I like to think we saved that little robin’s life. There was a little one then, alive and bouncing, and then a bigger one, dead and stiff.

God saw this.

What is it about seeing that is comforting? Wouldn’t catching the sparrow be more comforting? Wouldn’t solving the problem, ending the great horror – death – wouldn’t this be a more lasting comfort? You see me, God. You see my children. But if you were to let them fall…

Sharks close their third eyelid when they attack. This way they can see their victims without getting blood in their eyes.

Kai got out of the house when he was only one year old. We noticed when it was too quiet. He had slipped out the screen door moments after I arrived home from work, and neither Linnea nor I had seen him. I locked the door. It was five minutes before we noticed he was gone, and in those five minutes he was down the outer stairs of the apartment building and toddling along the street.

The terror in my heart: I was running down the sidewalk in my dress slacks, socks, and undershirt, desperately looking for my son, expecting to see him lying in the street, expecting to be one of those parents we pray for, expecting to live with the knowledge that we didn’t see him, we didn’t see him, and then it was too late to see him…

He liked stairs, so he had kept to the house side of the sidewalk, and a kind and observant couple had pulled over and were with him four houses down when I ran up. The man was on the phone with the police, and I heard him say, “Oh never mind, it’s okay. The father’s here.” I thanked them, breathless, and held my son, and held him walking back, and held him up the stairs, and held him for another hour until he didn’t want to be held anymore, promising him I would see him, always, I would see him.

God saw this. How can I say it differently, to ease the pain? God sees… me?

If we mourn this way, how must God mourn at all He sees, at all the flickering lights snuffed out, the bruised reeds broken, the sheep silent before the shearer? Death is nothing new to Him, and in fact, He knows it as an old friend, an old foe, better than us all.

Today, this day, my children are alive and real, perfect in form and surreally soft. They are the preciousness of young life, fleeting, and my God sees them. Lest you think me morbid, think on why this is precious, why as a parent, as a child, as a human I am determined to cherish this thing we call life, why I must defend it for those I love, why death is such an aberration and a destiny and a defeated foe. The thought of death is morbid, maybe, but so is the thought of life without the thought of death. For now, we need both. And God sees us, in both.

God sees us.

Peregrine falcons see too, because as they dive at over 200 miles per hour, they blink their nictitating membranes repeatedly to clear away the debris and clean each eye.

In the midst of holding onto my family’s break-neck life, I find that I am unable to bring myself to accept such a thing as death, and yet… I know that it’s what I must do, for we will all encounter it, sooner or later. This dark thing I wish to dismiss by forgetting, or fighting, or examining on the operating table of a small terrarium: Death will come for us all.  I know, in my spirit, it is good – a gift given so that our difficult, fallen lives will not last forever, but it will never lose its dread, even when it has lost its sting. And perhaps I will embrace it as a friend when more years have passed beneath my feet, or perhaps I will embrace my Savior, and He will carry me through it into the place where it cannot enter.

And my heart holds its breath for all the times I must try to prepare my children for that moment – the one I feel certain I will never be fully prepared for, the one that God sees. I know I am actually only trying to prepare myself. I know it is not up to me, and I wish I could take more comfort in that. Perhaps someday I will. Every day is another reminder that I am not in control, and death is the great Out-of-My-Control.

But I know this. Each day that I walk in the sight of God, He will train my eyes, and my sight can be strengthened by seeing life and knowing it itself is but a shadow of the life to come.

Nadia, my little avian maven, knows that birds need nests. So she settles herself in a patch of fragrant clover and picks flowers as a pillow for the bird. She is kneeling in her pink flowered dress, a lily ringed with gingham, examining the ground and plucking appropriate stems carefully, precisely, preparing for burial. Perhaps, preparing for flight.

And I blink back a tear.

Isn’t it strange, but also vividly true, that sunk in the deepest agony, some people lose their faith in God, the absolute sustainer? And yet others do exactly the same at the height of utmost pleasure. They forget that God is the sole provider. Either way, this entrenches the “in medio stat virtus” universal rule, which means virtue stands in the middle. This is what constitutes the dividing line between man’s meaningful living module (modus vivendi) for the Hereafter and the mistaken lifestyle “causing people to claim absolute independence and ownership of their self … leading one to imagine a realm of personal dominion,” as observed by Said Nursi in The Fourth Treatise in The Seedbed of the Light (pg 87).

Linking the initial paradox and Said Nursi’s soul searching words, brings to light one of the most interesting and captivating stories to appear in both the Bible and the Quran. This is none other than the story of Joseph – blessings and peace be upon him—and his brothers. Their riveting story cuts across humanity as it paints an almost unimaginable life of someone who never parted ways with His Creator – come rain when he was a slave and come shine when he was leading a palace life.  

While the Quran devotes a whole chapter (Surah 12 Joseph) and 111 verses to Joseph’s story with his brothers, the Bible tells it in 13 Chapters (37-50) and a total of 395 verses in Section Four of the Book of Genesis.

The story begins with Joseph, as the last child in the family of Jacob, born of Isaac, the son of Abraham, living in Moses’ promised land of Canaan (blessings and peace be upon them). Joseph draws envy from his brothers because of the special treatment he receives from his father, exemplified by a special dress.

His brothers also disprove of his chain of dreams, which they believe is Joseph assuming leadership; one particular dream sends chills even down his father’s spine. He talks of seeing, “the sun, moon and eleven stars bowing before him.” His brothers’ envy rages, but his father keeps this to his heart.

Lesson One: Did Jacob discriminate against his children? Very unlikely. As a prophet, he must have noticed something special in Joseph’s destiny and thus exercised extra caution to ensure the delivery of a sound and wise judgment. In the world of journalism, it is said “when in doubt, leave out.” In matters of faith in God, we ought to do what is expected of us while exercising enduring patience. No complaints. We must have pure sincerity and clean intentions.    

Lesson Two: What is in a dream? In dreams, all our five senses are virtually non-functioning. The dream drive – borrowing from the IT language – is external. That is why we travel distances above the speed of light from our bed pillows, as a friend told me.

At the same time, we cannot rule out cases of Divine warning about what is coming or ought to be done. Examples abound in the scriptures. In parts of Africa, dreams were originally taken for communication between gods and human beings, whereby the former made their wishes known. But an interpreter had to be there.

Lesson Three: Joseph’s brothers’ envy derives from prejudice, which is a vice to be fought against; it led them to treat their young brother unfairly. First they plot to kill him. Then they settle for dipping him into a waterless well and finally sell him to a caravan of Egyptian merchants, who resell him to Pharaoh’s Chief Steward Potiphar. He starts a slave’s life.

The brothers take his garment and soak it in goat blood. They send it to their father claiming to have bumped into it. Jacob laments. He goes into mourning. His children come to express their empathy. He takes no heed and keeps on mourning.

Through God’s providence, Joseph wins the trust of his “master” and is made steward of his household. He resists the temptation of his master’s wife. He chooses jail to breaking God’s and his master’s trust.

Again, he builds trust: the warden places him in charge of prisoners. There, he meets Pharaoh’s chief baker and cup-bearer. He interprets their dreams: the baker was going to hanged and the latter would be reinstated to his job as the Pharaoh’s cup-bearer.

Pharaoh himself is troubled by dreams. Egyptian interpreters fail to deliver. The cup-bearer remembers Joseph, who is called and manages to decipher Pharaoh’s dreams into seven years of good harvest and seven of famine on its heels. Joseph is made Pharaoh’s Chancellor. He helps the country store its food. When famine strikes, many people, including his brothers, come to Egypt for food supplies. He notices them. He sells food to them and orders their money stuffed back into their bags. He asks them to come back with their young brother as a condition for getting further supplies and orders one of them to remain behind as a surety.  

Lesson Four: The Roman’s “natura humana ad mala inclinatur” observation – meaning human nature is inclined to do bad things, becomes evident. The Chief Steward’s wife shows lust and anger. The chief-baker and cup-bearer display the fact that power corrupts. Man is forgetful. Men were busy looking for power and riches while women indulged in gossip, banquets, arranging amusements, and competing for worldly things.

Lesson Five: God never guides unbecoming behavior (Quran 12:52). For every holder of knowledge, there is (always) One more knowledgeable: the All-Knowing (Quran 12:76).

From all that has taken place in the fate of Joseph, it becomes evident that Destiny wills good for the believer. Although he was a slave at the palace, Joseph (blessings and peace be upon him) rejects the invitation of the noble, rich, and beautiful woman. He willingly prefers prison to committing sin.

Lesson Six: After introducing himself to them, his brothers start to feel guilty, which is the start of the process of reconciliation.

Lesson Seven: When hunger strikes again, Jacob releases Benjamin and orders the collection of an assortment of gifts and the return of the money which was stuffed back into their bags. He prays for God’s protection.  Upon arrival in Egypt, they are received but have to undergo another session of questioning.

After Joseph ascertains the presence of Benjamin, he is overwhelmed and takes a short leave. He sheds tears, washes his face, and returns. A grand reception is held.

Joseph orders bags stuffed to everybody’s carrying capacity. He orders to secretly place his special cup in the bag of the youngest, Benjamin. After they left, Joseph summons the supervisor and orders him: “Stop those people and ask them why they have returned bad for good?”

They deny any knowledge, let alone involvement in such unbecoming behavior. They pledge their innocence and that whoever would be found with the cup should face death, while they are ready to remain slaves forever. The supervisor differs with them. The one on whom the cup is be found will remain behind while the rest will be allowed to leave.

Benjamin turns out to be the culprit. In disbelief they tear their clothes and mount their donkeys back to town. Down on their knees, the entire entourage goes to Joseph’s residence.

He asks them: “What is this you have done? Don’t you think a person like me can prophesy?

 “The one to whom the cup was traced becomes my slave. The rest can return to your father in peace.”

“My Lord”, says Yuda, “may your anger not befall on your servant because indeed you are like the Pharaoh!” He goes on to narrate conditions under which Jacob may release Benjamin, listing the fatal family consequences of detaining him in Egypt.

Joseph is touched by the plea of Yuda. He loses control of himself. He orders the removal of all people. He tells his brothers: “I am Joseph. Is my father still alive?” They fail to answer. They are astonished.

He goes on to tell them: “Come near me.” They move closer.  He adds: “I am Joseph, your brother whom you sold to be taken to Egypt. But don’t grieve now. Nor feel bad because you sold me to be brought here, because God placed me ahead of you to save your lives. Quickly go up to my father and tell him. Your son Joseph says: ‘God has made me the Lord of the entirety of Egypt. Come down without delay. You will settle in the land of Goshen near me; you and your children, grandchildren, sheep, cows and whatever you possess.’”

Lesson Eight:  The entire story is one of affection and portrays the qualities of being keen, pure, and having sincere feeling with no ulterior motives and without seeking any return. Said Nursi puts it better in the 23^rd Letter (2:86-87), where he points out that the story encourages us to strive for the other side of the grave where we will find real happiness and pleasure. It also shows Joseph’s exalted truthfulness and announces that even the most joyful and brightest conditions of the worldly life could not captivate him; rather it led him to ask for death and the other life.

Lesson Nine: Via Jacob’s life, we learn that for believers who follow God’s ways without deviation and with pure intention, when things start to worsen, this means the happy end is approaching. The dawn of light is the end of darkness.

Note: The story of Prophet Joseph, peace be upon him, is narrated with some differences in both the Bible and the Qur’an. The author quotes from both sources in this essay.

Research on hummingbirds (also known as nectar birds or Colibris), the smallest of the 9,800 bird species living today, has revealed remarkable facts. The world’s smallest birds are equipped with mind-blowing structures and functions that push all physiological and anatomical boundaries. The bee hummingbird (Mellisuga helenae), considered to be the smallest bird in the world, is only 1.96-inch-long and weighs 0.06 ounces.

There are around 330-340 species of hummingbird and they live only in North and South America and the nearby oceanic islands. With their colorful feathers, they are some of the most beautiful birds.

How the hummingbird flies

A hummingbird flaps its wings so fast that the motion cannot be seen by the human eye but only detected through special cameras. The wings move at an incredible speed in a seemingly complex pattern, drawing circles back and forth 50 to 80 times per second, depending on the species. Under the genus Colibri, the horned Sungem (Heliactin bilophus) species flaps its wings 90 times per second; the purple amethyst Colibri (Calliphlox amethystina) flaps its 80 times per second. This speed increases up to 200 per second during a short spike while escaping from an enemy. Moving back and forth, the wings oscillate in the form of the figure 8 in the air. While in most other birds the movement of the wings produces the power to lift up and down, Hummingbirds, like helicopters, can perform movements such as hanging in the air or standing steadily as well as flying backward or rising in a vertical direction.

Figure 8

Metabolic rate and energy consumption

Flying requires a lot of energy. The amount of energy spent is related to the bird’s body size and flapping speed. In this regard, given that a colibri flaps its wings 80 times per second, it takes a great deal of energy to maintain such a rapid movement. The colibri’s chest muscles were perfectly created for flapping quickly and take up 40% of the hummingbird’s total body mass. Therefore, a colibri consumes more energy than other birds; it’s basically a fighter jet.

In order to meet this high energy demand, the amount of nectar a colibri consumes every day has to be equal to their body weight. Living at such a high metabolic rate requires a fine adjustment of food consumptions with precise calculations.

Such a high food intake requires a high metabolism – and thus, the need for oxygen increases dramatically. When the need for oxygen increases, there can be two kinds of conditions. Those animals with very large lungs can intake a lot of air at once. And those with smaller lungs can produce the required oxygen by breathing many times a minute. Colibri or Nectar birds are the ones that can breathe the most in one minute. The lungs of the world’s smallest birds breathe 250 times per minute to transfer oxygen to their hearts weighing a mere 0.003 ounces and beating 1,200 times per minute.

Toronto University’s Kenneth C. Welch Jr. studied the metabolism of hummingbirds for more than 10 years. He discovered that there is a relationship between the size of hummingbirds, energy efficiency, and oxygen consumption, and that larger hummingbirds are more efficient energy users than smaller ones. A hummingbird can take 2.44 cubic inches of oxygen per 0.03 ounces an hour. When a small weight is added to the bird, this amount increases to 3.66 cubic inches, and their tissues use oxygen very efficiently.

Energy requirements

A hummingbird’s metabolism is the fastest among all vertebrates. It needs to eat almost constantly to get the energy it needs to produce fuel for its breathtaking metabolism, which functions like a power plant. It receives nectar from 2,000 flowers every day. If we humans could work at this bird’s energy levels, we’d have to eat about 1,300 sandwiches a day to produce energy, and our body temperature would rise to 725 °F! Also, our hearts would have to beat 1,260 times per minute. Although nectar from flowers is the main fuel source driving the bird’s metabolic engines, it also occasionally eats insects, for protein needs.

During any given 30-minute period, hummingbirds burn the sugar they had taken in an hour ago. If we apply this rapid intake of sugar and the metabolic cycle in human beings, we would have to drink a large bottle of soda and burn the sugar in it every minute.

Unlike us, hummingbirds use both glucose and fructose from nectar in their intestines, circulatory systems, and muscle cells. However, we can support our bodies at urgent needs with an intake rate of 30% of glucose. Half of the nectar that hummingbirds take is glucose and half is fructose. In this modern age, high fructose derived from corn in our diets has paved the way for metabolic diseases and obesity – that is, people cannot metabolize high fructose.

Scientists are trying to determine how hummingbirds can process fructose. It is known that there is a carrier molecule different from glucose in fructose. This carrier is very rare in human muscle cells, but it is found in abundance in hummingbird’s muscle fibers; so we believe the mystery of how they utilize fructose so fast is about to be solved.

Hummingbirds have been equipped with mechanisms to increase the rapid introduction of nutrients such as fructose and glucose – which are basically small sugar molecules – or amino acids into their metabolisms. Their hearts and blood vessels work at a high speed to carry the sugar into their tissues as well as to transfer a lot of blood. In addition, a large number of capillaries have been implemented close to the muscle cells so that the blood can reach each and every cell.

Wing design

While humanity has not yet invented a machine that can move in a figure-8 pattern 80 times per second, including forward and backward, the ultra-flexibility of a hummingbird’s unique wing strokes demonstrates the special creation of its bones, muscles, and joints. The colibri’s brain and nervous system, which control these muscles and joints by transmitting signals, require infinite knowledge and power. The flexibility of the shoulder joint in the movement of the wings, which allows them to bend to extreme positions not found in other birds, gives us an idea of the wing’s unique design and architecture. Although biomimetic engineers have spent millions of dollars applying this complex system to technology, they have so far failed in their attempts to produce a similar machine.

Cooling the feathers due to the friction of the muscles and the tremendous movement of the wings is a problem in itself. While man-made machines need advanced cooling systems, the hummingbird has been created with a such a built-in system.

Unique tongue structure

Biologists from the University of Connecticut have discovered that hummingbirds’ tongues have a very special design and work like micro pumps. Tongues about twice the length of their beaks allow them to reach deep into flowers. The nectar is then pumped into the body in less than 1/20^th of a second. This occurs thousands of times each day. Tai-Hsi Fan and Margaret A. Rubega, who for a long time examined how hummingbirds stick their tongues 15 or 20 times a second into the tubular part of a flower, said that they “could not clearly understand how they drink the nectar.” In their latest study, they showed that it was only possible for the birds to hold nectar through two channels in their tongues. It was once thought that the physical rule of the upward movement of liquids in capillary tubes, even without suction, worked in the hummingbird’s nectar intake; but when special video recordings of the movement of their tongues were examined, it became evident that the tongue first compressed the nectar in a series of movements, then sprung up very quickly and the nectar was suddenly sprayed into the channels.

It would seem that both the hummingbirds and the flowers they need for sustenance were created in perfect harmony.

Red hummingbirds migrate from Alaska to Mexico every year. They can fly 56 miles per hour. Prior to this journey, they feed for one or two weeks to fill their fuel tanks, forming a layer of fat equal to half their body weight. Since these activities cause a lot of heat loss on the body surfaces, they cannot provide enough energy to stay active for more than 12 hours at a time. To counter this, they fall into a deep sleep every night for 12 hours. The energy storage, flight endurance, long-distance migration, and returning with the young ones are each complicated factors that their coming together to make this journey possible cannot simply be explained by blind chance.

Of course, the smallest bird in the world would have the smallest egg size: a mere 0.5 x 0.3 inches, for a total weight of 0.007 ounces. Considering that this wonderful bird’s design is embedded into this egg, which is about the size of the nail of our little finger, it can be understood how perfect a creation it is.

Serge and I were buddies. Our interests were largely similar. We were both interested in Oriental mysticism, travel literature, art, architecture, and ceramics. 

“The mystical part about making pots is whether you are in a good state when you make them, or anything else. Trying to achieve a good state by throwing pots as a therapeutic undertaking must be difficult. No, the state comes first and everything else follows,” I suggested.

“Sounds rather obvious,” Serge said.

“That’s the trouble, really. We expect our jobs, our hobbies and everything else we do, to give us peace. Of course, we must do our work with our minds, but the mind had better be in abeyance or you have no chance of creating anything worthwhile.”

“But artistic aspirations…?”

“I like basic aesthetics. Slender pots appeal to me more than fat ones. A fairly minimalist approach is evident. A traditional Japanese house delights me. I too, of course, wish to be empty.”

“How about architecture?” he asked.

“It is about form, which by necessity is governed by function. I greatly admire architects and I can feel their dilemma when attempting to combine form and function. The great architects give us spaces that are comfortable for our interior worlds. “

“But empty…?” Serge prodded.

“I suppose I mean the ability, the luck or grace to receive vision. I am convinced that any artistic endeavor begins with an inner vision. A quiet mind is almost a prerequisite. Then comes the work of getting stuff made, which I contend is the job of the mind. I once read that Mozart claimed to have seen music floating before him; he then had the task of getting it all down as sheet music.”

“So you equate throwing pots with a mechanical process,” Serge said.

I explained: “One obviously must learn the mechanics. I spent a year at art school learning how to throw in series. I was fanatical and everyone said I was crazy because I never fired anything. I once worked on a Greek island and was made aware of Greek potters who have little or no artistic ambition. They see working with clay in the same way that a mechanic works on a car. I heard about one potter in Athens whose wheel head never stops turning. Balls of clay are usually weighed to make certain pots and one then places the ball on a stationary wheel head, gets the thing turning, throws the pot, stops the wheel and cuts off the pot to be placed on a board. The man in Athens simply grabs a chunk of clay of about the right weight, whacks it on to a running wheel head, centers and throws the pot and cuts it off and removes it while the wheel head is in motion. He does that all day long, hour after hour.”

“Wasn’t it the Bauhaus people who spoke about a machine for living?”

“Sure,” I said. “But for them function was an aim. The rest was a philosophy of de-cluttering. Décor art also has a function, I hope, because it can get people forgetting themselves, if only momentarily, which I believe is the best way to experience pleasure.”

“What do you mean by forgetting yourself to experience pleasure?”

“It is quite clear – and many doctors and psychologists agree – that the activity of the mind can be repressive. Mental activity is seldom conducive to healing if taken to an extreme. A patient’s first thoughts are naturally the stuff of concern and the need to seek help! If the patient can surrender his or her condition completely to the expertise of the doctor, the doctor’s task is simplified because the patient’s mind does not meddle with the doctor’s work. More important, the mind is placed in abeyance and permits, or releases, the flow of a natural healing process.”

Serge was confused. “But how does creativity come into it?” he asked.

“One could say that any flow of natural energy, meaning not mind-induced, could be pleasurable. But it is not simply a question of absolute faith in a doctor because the mind in this very complex world has often formed what in German is known as an Eigendynamic, a life of its own, which means that the mind could take control of a person’s life and becomes a personal, overriding function. That which should be a person’s servant has then reversed the roles.

“Most people find a feeling of equanimity in a state of passive focus. I once attended a concert featuring Ella Fitzgerald and a jazz trio. The lady was in such fine form that within a few minutes she had captured the attention, the hearts, and the minds, of the entire audience, thus giving them a release from self. The feeling of euphoria was utterly palpable. Any great artist can give this grace to people. To look at a Rembrandt, at least for the first time, can be stunning – meaning, the mind is stunned. Bach, Beethoven, Mozart, and many more, were capable of offering such grace. I would suggest that truly great artists are themselves in a state of mind abeyance, as mentioned above, when creating their pictures, sculpture, music, literature, and architecture. Great artists ‘receive’ rather than ‘conceive’ their works.

“We are encouraged to be selfless, to simply let go of the thoughts that constantly bug us and turn to what we instinctively know to be true. True art, design, architecture, and hopefully ceramics, can therefore not only be pleasing but also beneficial.”

“Is humankind sick?” he asked.

“Not at all but there does appear to be a widespread feeling of dissatisfaction as we travel down our days. We have little repose. You might say we don’t give ourselves a chance to be truly happy. Was it Krishnamurti who said that there is only one thing between you and God: you. Get out of the way.”

“So you think a mystical approach would be useful?”

“I really do believe that, but, naturally, one would need the time to get quiet. Having a family, a job, earning a living and all the rest is hardly conducive to achieving equanimity from the outset. I can now make ceramics at my leisure but I admire those creative people who are able to achieve great work within the hustle of daily life, especially the young ones.”

“Looking at the pictures, there seems to be an ‘Asian’ approach to your ceramics.”

I said: “The master-potter, Bernard Leach went to Asia to learn about ceramics. He returned to England in 1920 and brought the Japanese master, Shoji Hamada, with him. Hamada and Leach showed us the possibility of selfless pottery making. They constructed and fired a wood-burning kiln, which, opposed to the radiant heat of an electric kiln, brings out the inherent qualities of the clay beneath a glaze. This is achieved by reducing the air intake at a critical point during firing because, obviously, a naked flame requires oxygen to keep burning. Thus the flame starved of oxygen seeks oxygen in the glazes and the clay. The result is buttery textures and some marvelous hues. I have a potter friend, however, who studied with Leach and he said it took years to escape from his influence.”

“But what of selfless pottery?”

“Again, it is the state of having one’s mind in abeyance. Leach maintained that if six potters were to each make a simple tea bowl and one of the potters was in a quiet state the result would be noticeable. In fact, he said that eight out of ten observers would instinctively choose that one bowl.”

“This would seem to imply meditation,” Serge said.

“I have nothing against meditation, but I never did it.”

“So what is your approach?”

“I do nothing really special: just get quiet, relax, begin, and watch what happens. I’m sure many others are happy with the way they operate.”

“Is there a learning process, in all this?”

I told him, “It’s like learning to drive a car, which is initially undertaken as a mental process. Beginners tend to be nervous. Gear changes get snarled, the rear-view mirror is largely forgotten, and so on. The mechanical learning process gradually becomes internalized and a natural flow takes over. Gear changes and all of the other skills become automatic. When this has occurred the mind is set free to concentrate, although focus would be a better word, on what is coming at you on the road.”

“So how did you learn?”

“It may sound far-fetched but one might say that the hands learned what to do. There is a marvelous video on YouTube showing the jazz guitarist Stanley Jordan playing a number (Jumpin’ Jack). Jordan has the ability to play melody and bass simultaneously, somewhat in the way a pianist plays. Deep into his solo one sees Jordan looking down at his hands and there is a smile on his face that seems to say ‘…hey, you guys are really having a good time.’”

“Oh come on, jazz and a quiet mind?”

“Jazz means improvisation engendered by freedom. The freedom from self, conflict, and anything else that hinders creativity.”

“Of course it would be impertinent to speak for other artists but I love the idea of what the Japanese call Shibui. It is a feeling engendered by quiet reticence, something that gives pleasure for reasons beyond explanation. I suppose it means a special rightness about something. Since I am not a Mozart, I do not expect to stun or startle with my work. I am satisfied if a bit of Shibui arises through a combination of shapes and glazes.”

“Talking about shapes…” Serge said.

“As I said before I prefer slender pots; pots that narrow down to a small foot. This gives the pot an appearance of floating – is soaring too presumptuous? My bowls usually have a turned foot. It gives them a lightness that I find pleasing.”

“Have you not been copying the painter Giorgio Morandi with his still-life renderings of ceramic vessels, especially the fluted bottles or those with cut sides?”

“I had never heard of the man before you mentioned him,” I told my friend. “But Morandi does appeal. Thanks for introducing me to his work.”

“The glazes are obviously an enhancement!”

“True but there is a lot of science involved. I fire with an electric kiln because it was given to me as a gift. We are too strapped for cash to buy a preferred gas or wood-burning kiln. My glazes have therefore been things to overcome rather than just use.”

“Build your own kiln!”

“I would love to but for the time being I am where I am at. The electric kiln I use is not particularly large, 60x75x50 centimeters inside, and it does have its eccentricities. All potters have this problem and have adjusted their glaze recipes and firing cycles accordingly. After several test firings, I have been lucky to achieve a good off-white, a really luscious chocolate black, a rather startling blue, a gorgeous dark green thinning to brown on the edges. I also have a nice pale green, which is supposed to be a celadon, but never really came out that way. I am still looking for a classic Chinese tenmoku glaze that fires at 1250°. It is a wonderful black breaking to brown on thin edges.”

“Your glaze application sometimes seems somewhat free-form,” Serge said. “What is behind that?”

“Well, if you have ever tried to draw an arc or a circle you will see the distinct wobble of the line because of an unsure hand. Just swish the pencil around on the paper and the result is likely to be much more graceful. You may not achieve a perfect circle but the result will be more pleasing to the eye. Lord knows how Giotto did a perfect circle in the thirteenth century. Splash glazing is a sort of just do it endeavor. There is no foresight involved, I dribble a glaze on to a pot and…”

“Watch what happens?”

“Right,” I said. “It is again the idea of not really putting one’s mind into a thing. Otherwise I dip my pots into a bucket of glaze in the usual way. Of course, large vessels must have a glaze poured over them, but it is still uncontrolled.”

“Clay?”

“The stoneware clay I use has been great help in achieving texture, although it is not very easy to throw. I mix two clays, with and without grog. The clay is speckled with pyrite and it looks good on the unglazed parts of a pot. The pyrite also shows through the glazes, especially in the off-white.”

“There seems to be lifestyle aspect in what you do.”

“I got around to it a bit late but consider myself lucky. We have a nice old house and a small pottery room. The garden is up and running. My marriage seems to be good, although I am definitely not going to ask her opinion about that. How you live, where you live, and what you do are largely a matter of circumstance for most people. An organized human environment is rather required.”

“Do you remember us talking about Francesco Patrizi, the author of many works of philosophy and the arts?”

“That’s right. He was looking for perfection of a sort,” I said.

“Patrizi wrote a book tantalizingly called The Happy Town. The work is Utopian and an attempt to counter Thomas More’s notion of separating church and state. Patrizi proposed the integration of both. He was born into the nobility in Croatia in 1529 and had the time and inclination to consider the improvement of the world around him. La città felice was written in 1551 in Padua and was printed in Venice in 1553, when Patrizi was only 22 years old. His book proposes a topographical situation that is obviously seen as the Croatian town of Cres in its deep, protective bay, and is about achieving an ideal state. We are confronted with a man who wished to create order, but it was order-imposed. His architectural notions encompassed ‘…straight streets to enhance winds in the hot season’ and ‘…streets meandering like a river to divert winds in the winter months.’ There were to be squares and institutional buildings for commerce, but his main thrust was the stuff of social order. Fabrizi proposed two social groups, the nobility, composed of soldiers and the priesthood, and workers and peasants forming a second group. This second group in The Happy Town were not actually meant to be happy but were only to serve and ‘…not to attain a state of bliss.’”

“Ho hum for Fabrizi. Thomas More was really a humanist, someone who cared.”

“Exactly!” Serge said. “Patrizi was an architect who wished to tell people what is good for them. One debatable point about art could be about what it does to people. Should art bring people to quiet reflection – bliss would be an exaggeration in my case – or should it provoke? Personally, getting people all riled up doesn’t make sense to me.”

“So what is the message?”

“Not offending anyone’s sensibilities, which means offering stuff that calms rather than antagonizes.”

“Your method…?”

“Get quiet, relax, begin.”   

“And watch what happens?”

“That’s about it.”
