As I gave my ears to the speakers, my mind took me all the way back to 1966. I realized that throughout the years I had witnessed many different developments without understanding what they really meant. A historical incident came to my mind: following the discovery of electricity, an exhibition was set up to present it to the public. At the exhibition, a guest asked Benjamin Franklin, “What is this new energy good for?” He replied with a question: “What is a newborn child good for?” It was obvious that human beings could not appreciate innovation very quickly. Yet, today we realize the importance and potential of this wonderful energy source.

Similarly, I had no idea that meeting Fethullah Gulen forty-three years ago would be the turning point of my life. He was a unique teacher who constantly astonished us with his extraordinary ideas. He was a person who did not limit his ideals to suggestions but acted upon them; hence, he was practicing what he taught. Gradually, I realized that his teachings, manners and unique behavior were no different to the teachings of the Holy Qur’an and the Messenger of God. In actual fact it seemed as they were a carbon copy of the Qur’anic doctrines.

Although we were aware of such Prophetic traditions as fasting on Mondays and Thursdays and also staying vigil at night, we had never witnessed anyone practicing these until we met Gulen. He would observe this Prophetic fast even in the tremendous heat of the summer in Izmir. Inspired by his total commitment to Prophetic tradition, we would hand him a list of the names of those of us who also wished to practice their faith as he did. Like an affectionate father, he would wake us up in the night so that we could perform the voluntary prayers (tahajjud) and join him at Suhoor (the pre-dawn meal to sustain us through the all-day fast). It was not easy to control the carnal self but the self-discipline and the feeling of tranquility that originated from this Prophetic tradition made it a unique experience.

During our stay at the boarding facility in Izmir, we also received additional lessons in our dorms. We were supported with supplementary classes which helped our education at local state schools. Our teachers were also experts on Islamic studies. They would work additional hours to help us with our studies, and even during lunch they would sit with us in the canteen to eat. Of course, they were all paid something for their efforts. However, Gulen was different. Salary meant nothing to him because he would spend most of it on students who were so poor that they did not even have pocket money. He refused to take any money for the additional work he did. There were times when he had given ten lessons in a day and then he took on the duty of staying at the dorm throughout the night. We were shocked to find out that he even paid for the food, electricity and water during his stay there. Talking about the notion of self-sacrifice is one thing, but witnessing it with your own eyes was an extraordinary experience which planted many new seeds in our souls.

We were amazed by the way he explained incidents that had occurred over one thousand four hundred years ago. He would explain stories about the Companions of the noble Prophet as if he had been among them at that very moment. His sermons were all about the practical interpretation of the Holy Qur’an. Everything we experienced felt like an original event. It was as if we were hearing the revelations from the Holy Qur’an for the first time in our lives. He was encouraging us to follow the example of the Prophet and his beloved Companions, and we were making the effort to do so. With every effort we made, a new door opened before us. It was as if we were entering into an entirely different realm as we tried to emulate the actions of the Companions. Eventually, there was no room for indolence or lassitude in our lives. As the famous Sufi poet Yunus Emre said, we enjoyed the gratification of being reborn with each new day.

Then came the day when we were encouraged to engage in educational activities that would benefit the whole of humanity. In all of us there was a unique sense that persuaded us to open a new era in the field of education. People who observed our dedication from outside were fascinated by our enthusiasm. One after another they came running to lend a helping hand. Students, teachers, merchants, shop owners and businessmen were all united in the goal of establishing educational facilities. Before long, private schools were established all over Turkey, followed by hundreds of schools all over the world. At the same time we started publishing educational materials, beginning with a bulletin titled Zuhur (Emergence). Eventually, this led to the establishment of magazines, journals, newspapers, radio and TV stations. These efforts, encouraged by Gulen, became so popular that a new horizon had opened before us of a global dialogue between cultures and faiths.

As dedicated volunteers of education and dialogue carried the welcoming smile of Anatolia around the globe, many sincere souls were attracted by its warmth. They began to visit Turkey, the home country of these self-sacrificing educators. Their visits were not like those of tourists. They had come to observe and understand the source of the enormous sincerity and the unique hospitality of the Anatolian people. On returning to their homelands, they explained what they had witnessed. You could see the excitement on their faces even after many months had gone by since their visit. This was another fruit of global dialogue.

As the conference continued at the Catholic University in Melbourne, my memories confirmed the significance of the work that had begun in Izmir many years before. Speakers constantly emphasized the praiseworthy efforts of these extraordinary educators and champions of dialogue. Silently, I said to myself, “What a great distance has been covered.”

One of the speakers was Orhan Cicek, Executive Advisor of the Australian Intercultural Society. He stressed that this conference was a great opportunity to strengthen Muslim–Christian relations. He said that this event, in which prominent academics from Australia and overseas were explaining their views and suggestions in relation to the vision of Gulen, was also paving the way to strengthen the multicultural structure and harmony of Australian society. He concluded with a wish that the event would become an important step towards cooperation that would attend to the common problems of humanity.

It was a wonderful event that gathered academics from Australia, Turkey, the United States of America, the United Kingdom, Germany, Austria and Indonesia. The conference dealt with the different aspects of the Gulen Movement and its practical approach to intercultural and interfaith dialogue.

During my visit to Australia, I also had the pleasure of meeting Barney Zwartz, a renown columnist from one of Australia’s biggest newspapers. In our conversation, he asked me about the future of this education and dialogue movement. He wondered how far it would go. I explained that we wished to reach every human being in the world and become true friends with them. He smiled and asked if such a dream was possible. I replied with an analogy. I said there is a story about an ant that decided to make the holy pilgrimage to Mecca. When they asked him, “How do you plan to reach Mecca with those tiny feet of yours?” the ant answered, “I am aware of the fact that I will never get there, but the least I can do is to die on the way.” On hearing this, Barney asked me, “Can I be your baggage?”

Rwanda is a country that has passed through a disastrous conflict and genocide with devastating effects. But the lessons learned in the aftermath of the genocide have changed the country forever.

Rwanda, a small country located in central Africa, has been home to nine million people from two tribes known as the Hutu and the Tutsi which have lived side by side in peace for centuries. There was no known ethnic conflict or major conflict between Hutus and Tutsis until the last fifty years. Rwanda was first colonized by Germany in 1899. Belgium took control of the country in 1919. In 1961, Rwanda’s monarchical government was removed by a referendum and the first parliamentary elections were held but at the expense of a number of massacres. In the following year, the country gained its independence.

Although the country became independent in 1962, the effects of colonialism lingered until recently. An example of this is the ethnic division between the Hutu and Tutsi tribes. During the colonial period, the Belgian colonizers and the Church significantly favored the Tutsis over the Hutus. The colonizers had followed a divide and rule strategy and used the Tutsis in power instead of controlling the country directly; this widened ethnic differences. The colonizers had made membership of the Tutsi tribe a means of getting better education or obtaining a government or administrative position. Since both tribes speak the same language and have the same skin color, it was virtually impossible to tell them apart, so the colonizers had issued ethnic identity cards based on the measurement of people’s nose length. Until World War II, the Tutsis were masters of the country with a proven long record. However, the strategies of outsiders including the Church had changed in the mid-twentieth century so that Hutus gained more access to positions of power. In the 1950s, the Hutus took power and controlled the country. Considerable numbers of Tutsis were exiled to neighboring countries on many occasions. Until the 1990s, Hutu power was largely unchallenged in Rwanda. However, Tutsi exiles were organizing in neighboring countries and this was perceived as a grave threat to Hutu rule. Political conflict over the control of power and resources resulted in an exponential increase in ethnic violence. The Hutu government conceived Tutsi empowerment as a threat to their own interests and launched a media campaign calling for genocide. After a chain of events, including the death of the Rwandan president in a plane crash, a terrifying genocide commenced. For a while, Hutu people were strongly encouraged to kill their Tutsi neighbors, and those who did so were rewarded for their actions.

As a result, the genocide exploded quickly between April and June 1994. The world did not attempt to prevent the massacres. Men and women, children and the elderly, all were identified by their ethnicity and executed wherever they were found. Hatred was at its peak so that even relatives turned against each other. While a Hutu husband was among the survivors, his Tutsi wife was killed, and their children were kept alive as they were seen as sharing their father’s Hutu ethnicity. More than 800,000 people (Tutsis and moderate Hutus), according to official records, were massacred by the army and the extremists.

At last, without any international help, the Rwanda Patriotic Front (RPF), a Tutsi-led rebel movement, overthrew the regime in June 1994 and the genocide was stopped. The country has been at peace ever since; however, Rwandans continue to struggle with the legacy of genocide.

After the Rwandan Genocide, one of the biggest challenges for the new RPF government was handling the detention and prosecution of more than 100,000 people who were accused of genocide-related crimes. Pointing to the seriousness of the situation one of the RPF government ministers said, “When we captured Kigali, we thought we would face criminals in the state; instead, we faced a criminal population.” The genocide orders were given by executives of the state but the crimes were carried out by hundreds of thousands of ordinary people. The pink uniform of prisoners is well known in Rwanda today since the transfer of prisoners from one place in the country to another is common. By 2000, approximately 120,000 people accused of genocidal acts were being held in the prisons, which were populated far beyond their capacity. In ten years, the courts have only managed to prosecute about 10,000 suspects. In other words, it would require at least another 110 years to prosecute all prisoners accused of genocide-related crimes. Although almost half of the prisoners have been released to ease the system at various times, the courts still need to work faster.

To overcome the backlog in the legal system the Rwandan government introduced the Gacaca (pronounced “gachacha”) courts, a community justice system inspired by traditional procedures for cultural communal law enforcement. Gacaca means “justice on the grass” and the court is launched in an open grassy area or village green, near the main street. The main advantages of these courts are the ease of assembling the court in public, and the way they provide the opportunity for everyone to exercise their right to speak through an interactive court. Gacaca is the latest means used by the Rwandan government to realize truth, justice, and more importantly the reconciliation and healing of the community much sooner than would otherwise have been possible. Rwandans have welcomed the Gacaca. One man who lost his brother in his twenties and another who abandoned his wife since she belonged to the so-called hostile tribe have found the Gacaca court in their local area a valuable place to express their feelings and seek justice in the shadow of ineradicable memories. Yet other people, who participated in the genocide, have found the opportunity and encouragement to admit their wrong-doing and relieve the pain of their remorse.

Gacaca has its pros and cons, which I will not go into here; however, the genocide carries important lessons both for Rwanda and the world. It showed how lack of tolerance and understanding of negligible differences can indeed turn into cruelty and brutality, resulting in one of the biggest genocides in history. Rwandans, who were previously divided as Hutus and Tutsis, now do not even pronounce the words Hutu and Tutsi in public in their daily life. Rwanda today exemplifies a good example of living together with differences despite the fact that those differences were recently the cause of a tragic conflict.

Indeed the Rwandan people, who once killed each other without mercy, can tolerate with no discomfort a diversity that in other nations is a great source of potential conflict, an area of interaction that other countries have been struggling with for a long time. Rwandans welcome all religious traditions in their cultural richness. Saturdays and Sundays are like a festival time; Christians all dress in their best clothes and walk to church. (Many Christians observe and practice Saturday Sabbath in Rwanda.) Although Muslims are in a minority, the adhan (call to prayer) is recited from mosque loudspeakers; the shifting Islamic holidays are accepted as national holidays. If religious differences were a cause of fighting, then Rwanda would still be one of the most problematic countries in the world today. In contrast, Rwanda is a good example of how the establishment of accountability combined with tolerance and understanding can help to transform and strengthen a country even when it has fresh memories of one of the biggest genocides in history.

For many, math is the most difficult class. Is it because of our own laziness, or is much math too abstract to comprehend? Ali Unver says, “educators who see the beauty at the center of mathematics and can make their students see it that way, are more likely to be able to get their students’ attention and teach them more effectively.” He explains in “Mathematics and the Universe” that mathematics is not only for keeping track of our checkbooks.

Mary and Jesus, peace be upon them, are the subject of a considerable amount of Islamic literature.

Drawing on sources of Islamic tradition and the Bible, Cetinkaya lays out interesting information on the topic, which is also a matter of debate between some Christian denominations.

“Can I Be Your Baggage?” Barney Zwartz, a journalist from Melbourne asks Abdullah Aymaz, who spoke about the emergence of the Gulen Movement in an international conference organized by the Australian Catholic University back in July. Whose baggage did he want to be? Zwartz was referring to the educational movement started in the 1960s among a small circle of young people like Mr. Aymaz who were inspired by Fethullah Gulen. In this issue, Aymaz shares with us his observations of the conference with some flashbacks to his first encounters with Mr. Gulen and how the movement started to take shape.

Two mechanisms of the mind

According to science, everything is bound to a cause. Without understanding a single cause or a set of causes, one cannot reach the knowledge of existence. Modern science, which does not accept the metaphysical dimension of being, does not seek wisdom in the creation; rather, it only searches for a cause–effect mechanism that is based on self-interest. For modern thought, all individuals are the lords of their selves and they interpret life according to their own reasoning.

In reality, however, the mind works in two ways: it is either a toy in hands of the nafs (the evil-commanding self) or it functions as a department of the heart. Thus, one can either think with one’s evil-commanding self or with one’s heart. In the former case, since everybody thinks according to their wishes, there is no doubt that an environment of chaos will emerge in social life. Modern philosophy, however, relying upon a wrong perspective, generalizes this idea to the entire existence and imagines the universe as an environment of chaos. For this reason, Frederic Nietzsche argued that the good is to acquire power, and he divided people into two groups, the aristocrats (or powerful) and the ordinary. In this view, those who are materially deprived seek to escape material realities and try to find a source of empowerment somewhere else in order to satisfy them. Hence, searching for metaphysical truth has its roots in lack of power. In reality, however, is impotence a result of non-recognition of religion, or is it a reason to search for metaphysical truth or religion?

The impotence of human beings

Indeed, human beings, who are in the best form among all living creatures, do not own themselves. To give an analogy, consider that a soldier has some money. If the money is granted to the soldier to be employed in the service of the government, he can only use it in certain ways. In other words, the soldier does not have absolute ownership of the money. Similarly, human beings do not absolutely own themselves or their bodies since they cannot always use their bodies as they wish. Sometimes, they become sick; they even cannot raise an arm when they want to. The very fact that they die against their wishes shows that they do not have absolute ownership of themselves or their bodies.

Human beings, if they do not lose their mind and awareness, see the world as a place of mourning since they feel pity at the sorrows of others. However, in the eyes of modern man, who assigns every self (nafs) absolute ownership, this world is a place where brute force triumphs because, as Sartre asserted, humans are left to themselves as they do not know what they should do. According to this view, what is heard everywhere is the voices of tyrants and the mourning of the oppressed. The contradictions of this modern view, which overlooks religion, have loaded humans’ hearts and souls with burdens of grief and have granted them impotence. Here, what I mean by “impotence” is that condition of spiritual weakness of the one who learns the outside world while having no point of reliance within the self.

The understanding that “conflict is always essential in the world” is based on a totally wrong perspective as well. The help and assistance of the sun and the moon to plants and animals; animals (and plants) being put at the service of humans; food materials being found in nurturing fruits; atomic sustenance nourishing body cells are some examples that show how helping one another is an obvious truth in the world. This fact is so critical that even an absence of one cause in the universe could lead to enormous negative consequences. For instance, let us imagine nitrate bacteria were to be absent in the circulation of nitrogen. In that case, plants would not be able to use nitrogen, their metabolisms would be greatly weakened, photosynthesis would stop, oxygen in the air would decrease as carbon dioxide increased, and the earth would turn into a place which would not support human life. Likewise, small or big, all kinds of balances in the universe indicate a law of reciprocal help and assistance.

The place and nature of causes

Additionally, assigning all events to certain results and regarding causes as the absolute power in the universe is a result of modern philosophy’s being deprived of transcendental truth. Bediüzzaman Said Nursi summarized the influence of causes thus: “For physical causes only gather and join together. It is confirmed by people of reason that they cannot create out of nothing what is not present in them.” When an ordinary result is looked at, a deep consciousness, a transcendental knowledge and supremacy and similar attributes are seen. Causes do not own these attributes and therefore cannot be the real architect of the result. Besides, every cause is contingent (al-mumkinat, plural of mumkin, or “possible”), its presence and absence has equal consequences. Therefore, every cause depends on another cause, which depends on a further third cause, in the same way as the feet of chairs lean against one another for support. At the end, however, for this chain to stand, there is still a need for One who is not contingent, whose presence is essential and of Himself (Wajib al-Wujud), and who is the Causer of causes (Musabbib al-Asbab). If human beings, who can be considered as the most developed cause, cannot create the tiniest thing from nothing, then no other cause can possibly be the real architect.

Thus, a human being who thinks according to modern science of trying to get knowledge of the physical world through pure reason and experimental method will assign everything (from the smallest sphere to the largest one) to causes. Since the “modern” scientist regards the perfect balances that he or she discovers, from those in one small cell to those in the universe as a whole as a gift of causes, he or she thinks that any cause can also destroy the perfect stability; for destruction is much easier than construction. Therefore, modern scientists load an enormous burden on their backs. All the discoveries that they make and everything they assign to causes in the path of science will soon become a source of fear for them. Now, knowledge grants them impotence. Under the pressure of this subjection, they seek a source of empowerment. It might sometimes be their own self (or ego), sometimes technology, and at other times nature.

As can be seen, contrary to the arguments of the mechanical worldview that separates metaphysics from physics and regards causes as sources of everything; and as opposed to the “modern” understanding that assigns absolute authority to every self, assumes chaos in the world, and considers force the only way to win a conflict; turning to belief is not because of impotence. On the contrary, it is one’s not turning to belief that results in impotence and helplessness.

This attitude usually adds to the tyrant’s courage, makes the slanderer even more impudent and the assailant more outrageous. Still, I say to myself, “They are human too, and one day they will realize it and they will give up such impertinence.” This is perhaps wishful thinking or a misapprehension, but I prefer waiting for a blissful hour when everyone will come to reason and mercy. Filled with some bizarre supernatural expectations, I endeavor to soothe my exasperation and stand firm against the storms that challenge my lenience. I sometimes dive into a deep, silent introspection to escape my own realm of feelings. There are times when I feel sorry for myself in the face of some agonizing events, and I am troubled with a passing sensation that I am perhaps disrespecting myself while trying to be respectful to everyone else. But still, in spite of so many lies, fabrications, and devilish schemes, I turn to myself and say, “You have assumed trouble as your healing from the beginning; then what is this protest for? The one with teeth will certainly bite, and the one with claws will rip through; no one can change this as long as those who consider the truth to be with the powerful continue to exist. Be tolerant to everyone.” I bury my cries inside and pronounce my feelings with silent woes.

Indeed, it is impossible for people in my circumstances who share this way of thinking with me to act otherwise. First of all, we do not submit to the wicked ones, but “to the decree of fate we wholeheartedly submit our souls” (Bâkî). Secondly, we live in a time in which people in great numbers are locked onto hostility; today’s revenge-thirsty figures overshadow in ruthlessness the abominable tyrants of the past-so, tempering the atrocities in my heart does not change the reality. Many billow with the rage of pharaohs when they speak; their hatred and violence never abate and their hunger for blaze, destruction, slaughter, and extrajudicial execution is never satisfied. They raise their swords to the heavens like He-Man and scream, “I have the power!” The world all over echoes with the chorus of “Justice, freedom, democracy, civil rights,” but justice is desperate in the hands of crude power, freedom is leashed with the straps of slavery one over another, democracy is a freak in the hands of enforcers who interpret it capriciously. There is no one left who does not understand this, but those who have conducted decades-long abuses continue singing the same tune, as if they are unaware, with no sense of self-respect, and debasing their own social status. With no other occupation, sitting in sloth, they speak on behalf of rights, freedom, and democracy, while others who violate these values in broad day light utter the same words. These are words of magic invoked to earn status and esteem, and then circumvented to legitimize corruption and fraud. Oppressors rely on them when they oppress some people while favoring whoever they favor. These are the words offered as legitimate governments around the world are interfered with and countries are invaded. “Bringing prosperity” is a pretext for shedding blood and dishonoring others. With the same excuse, murders are committed, killings are left unsolved, people are tyrannized, free speech is censored, privacy is violated, religious persuasions are harassed, unthinkable profanity and what is forbidden are replete and promoted; civil rights and justice are frequently pointed to, but are trodden down at the same time.

Nowadays, I am observing all these horrors and calamities through my narrow vision, and I mumble, “O Lord, how forbearing you are! You continue to grant respite to the perpetrators who are responsible for all this violence, oppression, and degradation of rights, freedom, and democracy. Absolute might and power belong to God.” And then I bury myself in a silence of astonishment and amazement (dahsha and hayra) , which I feel has become part of my nature. Absolute silence in the face of injustice, tyranny, and violation of rights is no different than glorifying Satan and is condemned in a Prophetic tradition. Indeed, believers never remain in absolute silence; if their hands are tied, they speak out; if they are gagged, they reveal their fervor with overflowing gestures; if they are ostracized completely from society, they expand with palpitations as if they had a volcano heaving inside. If their internal explosions could be unveiled, we would witness bolts of lightning issuing from their hearts and chill from their claps of thunder.

Their quiet stance arises from their subtle refinement and vast compassion which would not disdain even an ant, from their philosophy of security and trust, respect for human values, mercy toward everyone, and from relying on God in all matters. First and foremost, they are people of fine balance. Even when the most horrific waves of unrest beat the shores of their hearts, they behave with the utmost moderation and prudence. They never act unwisely like a child whose imagination outweighs his reason and comprehension, who blabs everything that crosses his mind without a moment’s thought, who is concerned with accountability only after destroying everything with his words and actions and seeks excuses for the destruction he has caused. They are always aware of their position, of what they do and say, and act with discretion in the balance between their hearts and minds. When they are granted the opportunity, they pronounce universal human values; when they have to remain silent, they act out these values with fervor, keep up their prayers and invocations, observe with compassion, and smile on everyone. They are never upset by their fate, nor do they complain to others as if dissatisfied with God Almighty. On the contrary, they question their own selves and seek their own faults. They bury their sorrows in their chests and do not mention them to those who are unable to comprehend; not a word of discomfort can be released from their mouths even though they may burn like an oven on the inside. They die and come back to life, but never do they disclose this to anyone.

No one can know completely what a burning mass of white-hot embers they actually are; others consider these special people no different than themselves. Yet, if their belief, demeanor, and selfless spirits that are devoted to making others live were to allow them to roar out their internal fervor, all the crows would immediately hush and look for a hidden corner to take refuge in, while all the bats would retreat back into their dark caves and descend into silent introspection. True believers are men and women of trust and security who show the utmost care in performing what their true character necessitates. They never hurt others, even though they may be hurt; nor do they cause pain, even if they are tortured.

In fact, their spiritual realm is replete with portraits of sorrow, each more horrifying than the last, that exist side by side with their feverish passion to relieve society of its ailments. Their palpitations and pains last forever with constant brainstorming and attempts at revival. The eternal verses of their hearts or, more truly, their silent cries, are a call to the light with a commitment to illumination as opposed to darkness. One line of the poem drops from their lips in grief, while the next inspires revivification. Their indignation and enthusiasm reveal signs of all this incessant internal turmoil.

Indeed, this has been the kind of life we have always sought, or perhaps we have been forced to live in this way. Fervor and sorrow have been our fate and in fact what we have also demanded. We have considered living for our own sake as selfishness, an attitude we have always abhorred. The motto “So others may live” and wishing eternal happiness for all have been our passion. This passion is so intense that if it were at all possible to come back to this life after death and we were given the right to choose, we would still prefer others’ lives to our own. The true horizons of humanity we would fix our direction towards; thoughts of revival we would breathe with; degradations we would close our eyes to; fuss about fundamentalism we would not be deceived by; those who come forward with slanders, calumnies, and accusations we would not be upset by or despair at; unrelenting violations and attacks of the severest kind we would bury in our chests; when it hurts inside, we would still manage to smile; when the magma inside erupts, we would suppress our exasperation so that no one is hurt or disturbed; and we would always display the privilege of being human.

I feel that those who think we remain in total passive silence and those who think we are involved in some kind of “activism” are all wrong. We are never absolutely still-anguish and hope, enduring everything, and striving for survival, all coexist in the depths of our souls. We may sometimes lose spirit, but never to a level of termination for good. Even if only with half of a voice or a breath, a quarter of a pain or palpitation, our hearts are like a brazier with embers always burning inside. Our faith constantly whispers new sentiments to us, and our conscience plays tunes of all kinds. Nevertheless, those who are of not the same persuasion or ideals as us cannot hear any of these melodies nor can they comprehend any of these sentiments.

Personally, every time I think of this agitation and fervor, I tremble as I visualize innocent people who have been victims of deadly imprisonment, maddening persecution, and merciless hounding, and whose words were stuck in their throats, words they wanted to utter but could not, so they were choked almost to the point of death. Who knows what beautiful things they would have said. The ignorant who did not know, even worse, those who did not know that they did not know, and the worst of all, who thought they knew even though they did not, used all available means to prevent those innocent people from expressing themselves; they would never allow them to do so, for if they did, people would understand how bereft of ideas and knowledge are those persecutors. In the words of Akif, the miserable oppressors “do not look to the East, nor are aware of the West, nor have any share of good conduct / All they have as capital is a face that cannot blush and eyes that cannot water!” If they did allow the innocent to speak up, those who can reason would comprehend all these matters and discover the true identities of some of these ignorant ones who tie justice to power and resort to despotism, whose assets are no more than yelling, and who try to catch fish in muddy water. Then, all the wretched souls who fight against common sense with dialectic and demagogy would topple one by one, their false candles would blow out, and those who have been deceived would not be tricked any more. All this would end in the collapse of those who want to rule the world with crude power, and I do not think they would ever acquiesce to that. In any case, we end up with the fact that today some people are gagged, while many others remain indifferent.

Those who cannot express themselves today in one way or another, will certainly voice their internal vibrations and pain, be it merely in their comportment; in return for their gulping down their words with palpitations today, they will recite the best poems of silence when the day comes. Who knows, perhaps then many rude and cruel characters who have forgotten true humane values like compassion, mercy, and justice for several centuries now, will unexpectedly melt down and turn into whatever being truly human demands.

So, let tyranny enjoy itself for a bit longer; let civil rights and justice be trodden on; let the innocent moan with pain; let the wronged strive to voice their grievance; and let hearts breathe with grief and fervor, hoping for a blissful hour in which the All-Powerful will speak. For us, if it is a matter of time serving our time of trial and lamentation, then, as in the words of Faik Ali, “There are songs yet unfinished / Anticipation moans in their silence,” there is still need for more quiet lament, after which perhaps the spring will rise.

Some people might see me as a rough piece of flesh that wiggles in the mouth. Of course I am not that simple! By looking at my color, some experienced doctors can even diagnose an illness. For example, some well-known symptoms that I show are whitening due to fever, becoming dark brown when you have typhoid, blackening because of a yeast infection, or having a smooth surface because of anemia or lack of niacin (a B-group vitamin).

If you are wondering what my primary duties are, I can say that the first is to help to produce speech, an ability which distinguishes you human beings from animals. For sure this speech production is not only mine. First of all the brain, which is the coordinator of all the organs including me, regulates all my movements in speaking. The other organs that help me form sounds to make words are your teeth, lips, palate, the vocal cords in your throat, and your lungs, which work like an air pump and vibrate those cords. As you see, so many of us work together just to produce your speech.

Other than the speech function, my second major duty is to work as an inspector to taste and process the countless fruits and delicious foods that are given by God. That is how you get an idea about an animal- or plant-based substance that you want to eat. If I did not exist, you might die because of a poisonous plant that you ate out of hunger. Many poisonous substances have a bitter taste. Indeed, I can sense their bad taste the moment I touch them and warn you to spit out the thing in your mouth immediately. When you eat sweet and delicious things, however, I make you remember and thank God, who has given them to you. However, you should be careful about my fondness for taste and control yourself since that is part of a God-given test. My Creator has made a relation between my love of taste and the evil-commanding side of your soul. He has also made me a step for your spiritual development. If you eat and drink too much, which means you are misled by your evil-commanding side and abuse my sense of taste, it will be you who lose. I do what my duty requires and get the taste of everything. But it is your job to use your will power and not to be defeated by your evil-commanding self (nafs). I will never stop you, whether you eat one piece of baklava or ten; I will get the taste of every piece. Do not ever blame me for that!

I have another function that many people are not aware of. My movement causes a negative pressure in the cavity of the mouth. Are you wondering what this negative pressure does? This pressure is needed especially for babies to nurse on their mothers’ breast easily; I help them in the sucking movement. In addition to that, as everybody knows, I have very important functions in chewing and swallowing food. I manipulate the food in your mouth; I soften and moisten it with saliva so that it can be easily swallowed. Also, during swallowing, I move the food back toward the pharynx. I have to be very careful while doing all this, since at my smallest mistake, your teeth might bite and hurt me.

Of course, I can do all this only with the help of my Creator, who has built my anatomy of delicate tissues and cells. Since He never does anything absurd or useless, He has given every organ qualities that are both esthetic and functional. My main body consists of seventeen muscles, eight of which are in pairs. They extend in all directions. Among those muscles are the lipid membrane and some salivary glands. I am the most flexible organ in your body. My many strong muscles enable me to move in lots of directions easily. Those muscles are covered by an epithelial lining which is called the mucous membrane. The small projections on my upper surface are called papillae. These papillae are of several types. They contain receptors which allow you to sense taste and the salivary glands that help me stay wet all the time. The papillae cover as far as an A-shaped line towards my back which makes up a third of my length. Here at my back, there are plenty of salivary glands and the lymphoid tissue, also known as the lingual tonsil. Many germs that enter through your mouth get trapped here. The papillae are named according to their shapes. The filiform papillae (which are long and thin) do not contain taste buds. They only provide a rough surface to move the food easily. The food is moistened by your saliva and crushed by your teeth. Then, with the help of these papillae, I help to shape the food into smaller pieces to make it easier to swallow. The fungiform papillae are mushroom-shaped and scattered among the filiform papillae. They are located at the center of my top surface and they contain taste buds. The circumvallate papillae lie along the A-shaped line which makes up the border of my back. These papillae are larger in size and smaller in number; there are around thirteen of them. Each taste bud on the fungiform papillae has 50 to 75 receptor cells which live for only seven to ten days. When cells die because of hot or acidic foods, new ones are created to make new nerves for the taste buds. Only substances that are dissolved in water can reach the taste receptors. That is why I cannot taste a dry substance that you have taken into your mouth right away; it has to be moistened and softened first. Tasting occurs in the receptor cells of taste, where some analyses are undertaken much more delicately than in a chemistry laboratory. My receptor cells change this chemical stimulus into an electrical stimulus and send it to your brain. This electrical stimulus allows the sense of taste to be perceived.

Among the many kinds of taste, there are four major groups. The taste buds for sweetness are located near my front; the taste buds for saltiness are scattered widely on my surface; the taste buds for bitterness are found at my back; and the taste buds for sourness are on my sides.

My under surface extends between my tip and the floor of your mouth. The mucous membrane that covers this surface is smooth and does not contain papillae. It is purple in color because of the many blood vessels that are inside me and nourish me. By the way, the famous saying that “the tongue does not have a bone” is wrong, since I do have a bone. However, this bone is not located in my front body, which is why I am very flexible and I can say whatever you command me to say. But by my muscles and ligaments I am firmly bound to a U-shaped bone (the hyoid bone) at my root. I am connected to your lower jaw by this bone.

I can have disorders, like every other organ. In fact, many disorders in me are an indication of disorders in the other organs or of a metabolic illness. For example, mouth ulcers can often be seen on me. Some types of mouth ulcer are caused by stress, lack of sleep, or lack of vitamins. Others occur as a result of absorption disorders and as a symptom of Behcet’s syndrome. Some ulcers can last for weeks and they can be very painful. You might suffer from this pain especially when you speak and eat. Diseases such as syphilis and herpes also show themselves as ulcers on me. I might even become cancerous in people who smoke or in those who eat and drink things that are too hot. I sometimes show the symptoms of some metabolic disorders like Down’s Syndrome, the blockage of lymph vessels, glycogenosis and amiloidosis. In these disorders, my muscle mass shows excessive growth due to abnormally deposited glycogen and amyloid.

Dear Peter, until now, your “speechless organs” have talked about themselves in their own tongue. I have always talked, but I have always talked on your behalf, expressing your thoughts and feelings. It is you who are responsible for what I have said, good or bad, since I am bound to your will power. However, today I spoke in my own tongue, and on behalf of our Creator. As is well known, I am an organ that has great potential for both evil and good. It is your duty to control me and use me well. Do not ever forget that I am not a simple mass of muscle, epithelium and nerves. Rather, I am a tool that can be used for both debasing and elevating you. From now on, when you eat an apple, do not swallow it before chewing well; wait till I get the flavor of it very well. In that way, you will have an opportunity to thank God for the food you are given. He is the One who not only gave you that apple, but also me, the organ that can taste it. This is just another amazing thing that makes your life beautiful! By thanking God, you will deepen your worship of Him.

Educators who see the beauty at the center of mathematics and can make their students see it that way, are more likely to be able to get their students’ attention and teach them more effectively. Also, as well as facilitating the study of sophisticated mathematics, this puts mathematics in its proper place so as better to understand the value of what it has to say to human beings. To see the beauty and the pleasure in mathematics can change the negative attitudes of some students and help educators in teaching mathematics.

Often it seems that we pursue mathematics education from either a structural or an applications point of view. From a structural point of view, we insist on building up all of the tools one may need in a sequential, logical order, because an educator will need the students to know all of the smaller pieces before they can build any of the larger ideas. An analogy for this would be if we forced somebody to study all of the nails, screws, bolts, and tools to build a house before we let them even see the plans for the house. This is one of the main reasons that most people who study mathematics in their school years think that it is a pointless exercise in playing with formulas and has no significance in real life. For these people, mathematics might be helpful only in keeping track of their checkbooks after graduation. Some students think that they can calculate whatever they need using computers, but sometimes this is not very effective because students may not understand the logic behind the problems and the results do not mean anything to them or they are unable to detect errors.

The applications point of view leads to making up “word problems” that appear to be about the real world, but everyone knows that they are highly artificial. It also leads to focusing at higher levels on only the applications. Hence, for instance, in calculus we spend a lot of time plodding through various physical applications, without letting students see the bigger picture. Or we spend time in liberal arts mathematics talking about things such as modeling and linear programming, which yield great applications, but are generally tedious and do not give most students much appreciation for mathematics. If we see the beauty at the center of mathematics, as well as introducing ideas that may have application or may build some tools, we can bring students to have a much bigger picture of mathematics at a much earlier stage in their mathematical development.

Educators can include some fun topics in courses that they teach. For instance, they can encourage students to discover the amazing number patterns in nature, such as the Fibonacci sequence in pine cone spirals, pineapples, and cauliflowers, in which the number of pieces increases in the following manner: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 … (add the last two numbers to get the next). Another example is the “golden ratio.” In mathematics and the arts, two quantities are in the golden ratio if the ratio between the sum of those quantities and the larger one is the same as the ratio between the larger one and the smaller. The golden ratio is a mathematical constant, approximately equal to 1.6180339887 and recent research shows that people think that the shapes and figures in this ratio are more interesting and aesthetically pleasing to the human eye.

Sometimes, even a small algebra trick can miraculously bring students to love mathematics and be more focused, and then more interested in the deeper aspects later on. Take a look at this symmetry:

1 x 1 = 1

11 x 11 = 121

111 x 111 = 12321

1111 x 1111 = 1234321

11111 x 11111 = 123454321

111111 x 111111 = 12345654321

1111111 x 1111111 = 1234567654321

11111111 x 11111111 = 123456787654321

111111111 x 111111111 = 12345678987654321.

Here are a few more examples showing the beauty of mathematics visually with numbers:

1 x 9 + 2 = 11

12 x 9 + 3 = 111

123 x 9 + 4 = 1111

1234 x 9 + 5 = 11111

12345 x 9 + 6 = 111111

123456 x 9 + 7 = 1111111

1234567 x 9 + 8 = 11111111

12345678 x 9 + 9 = 111111111

123456789 x 9 +10 = 1111111111

9 x 9 + 7 = 88

98 x 9 + 6 = 888

987 x 9 + 5 = 8888

9876 x 9 + 4 = 88888

98765 x 9 + 3 = 888888

987654 x 9 + 2 = 8888888

9876543 x 9 + 1 = 88888888

98765432 x 9 + 0 = 888888888.

Students’ minds can be broadened by seeing the surprising differences that arise when we move to non-Euclidean geometry. Fractal shape examples in nature, such as snow crystals, and things like the Mandelbrot set, which is a set of points in the complex plane the boundary of which forms a fractal, can be introduced with a background and give rise to amazingly beautiful images and ideas. Even such deep and thought-provoking ideas as these can be understood by students when they have curiosity, creativity, and an open mind.

All these examples and others like them can inspire people to see the beauty of mathematics and give them a better understanding and a sense of the expanse of mathematics. With a little more discovery of and exposure to the more beautiful aspects of mathematics, students are much less likely to feel any hatred for mathematics and may develop a much greater appreciation for the creation of the universe.

Note

* The golden ratio can be derived by the quadratic formula, by starting with the first number as 1, then solving for the 2nd number x, where the ratio [x+1]/x = x/1 or (multiplying by x) yields: x+1 = x2, or a quadratic equation: x2-x-1=0. Then, by the quadratic formula, for positive x = [-b + sqrt(b2-4ac)]/2a with a=1, b=-1, c=-1, the solution for x is: [-(-1) + sqrt([-1]2 -4*1*-1)]/2*1 or [1 + sqrt(5) ]/2. See the second reference for details.

A:

“They are utterly deaf, dumb, and blind; they can no longer recover.” (Al-Baqarah, 2:18)

“They are deaf, dumb and blind, and so they have no understanding of (what is said to them).” (Al-Baqarah, 2:171)

One of the above verses is about hypocrites; and the other is about unbelievers. As clearly expressed in these verses, the state of hypocrites and unbelievers are considered as equal to being deaf, dumb, and blind in their difficulty to digest the truth, in the way they view events, and in their injustice. However, the two verses differ in their essence: one of them implies for these groups inability to find their original disposition (fitrat al-asliya) and former state of being, while in the other verse there is an emphasis on failure in using their reason. What joins these groups in their common deafness, dumbness, and blindness is the fact that both cannot evaluate truly the “book of the universe,” a book laid out before their very eyes in the form of an exhibition so that they can find out about the Almighty Creator; they cannot analyze the cosmos comprehensively, nor can they interpret events by reading between the lines. They do not give the slightest importance to the books, nor do they lend a listening ear to their conscience.

If they had made good use of the books and their conscience, then they would have been able to testify to the truth-as the believers do-by using their intelligence. This way they would also have returned to their original innate nature; as a result, they would have lived their lives according to God’s commands and prohibitions. Truly, they are deaf because, while every creature in the universe announces the existence of God in its unique tongue, they are incapable of hearing that. They are dumb because they are incapable of acknowledging what they feel in their inner consciousness. They are blind because they cannot see the ways which lead humans to the truth of God’s existence and His oneness.

To consider more deeply these verses, “La ya’qilun” is used for the unbelievers, meaning that they do not use their intelligence and they do not actually think. As a matter of fact, if they had taken time to think, then they could have found the ways leading to faith easily. Indeed, the obstinate unbelievers of the city of Mecca had persecuted the Prophet Muhammad, peace and blessings be upon him, and his companions for long years. Yet, when they truly recognized how Muslims were and how they lived in an environment of peace after the Hudaybiya Treaty, the unbelievers turned their heads towards the right path saying, “We have been in great error!” For such a level of realization to be possible for unbelievers is largely dependent on their endeavor to think and to make a rational assessment of the situation; thus, the Qur’an concludes the verse about unbelievers with the expression “La ya’qilun.”

The Qur’an describes the hypocrites as follows: “Vacillating between (the believers) and (the unbelievers), neither with these, nor with those” (An-Nisa 4:143). In other words, they frequently go from one place to the other; they represent being deprived of light both in their vision and in their conscience. In addition, as they limit their lives to this world, they have been living in indifference and recklessness in this world. Belief and unbelief do not make any difference to them; they desire to live in a place where the living standards are high and where they become comfortable. Hence, they even go to the masjid and pray when necessary; nevertheless, they pray ostentatiously and lazily, as the Qur’an says: “When they rise to do the Prayer, they rise lazily, and to be seen by people (to show them that they are Muslims); and they do not remember God (within or outside the Prayer) save a little” (An-Nisa 4:142). This demonstrates that the hypocrites, in one sense, keep living in an Islamic way and they even follow the Prophet; nonetheless, they are still far from seeing the truth because their hearts are veiled and their thoughts are far from faith and sincerity.

Therefore, the biggest problem of the hypocrites is their insincerity. Accordingly, the Qur’an uses the expression, “La yarjiun” -“they cannot return to the truth and the purity that they originally had”-for the hypocrites as a characteristic. Also, the verses in chapter Al-Munafiqun (The Hypocrites) are concluded either as “La ya’lamun” -“They do not know”- or “La yafqahun” -“They do not understand.” Expressions like “La a’qilun, la yatafaqqarun” -“They do not consider, they do not think”-are not used for hypocrites because those expressions are the attributes of unbelievers.

He has granted you from all that you ask Him. Were you to attempt to count God’s blessings, you could not compute them. But for sure, humankind is much prone to wrongdoing (sins and errors of judgment) and to ingratitude. (Ibrahim 14:34)

Today a large part of modern science focuses on understanding the human body. Researchers working on life sciences hope that one day the secrets of every single detail that make us human will be revealed. Every year billions of dollars are spent by scientific institutions on learning more about us. Actually this fact by itself is enough to suggest how little control we have over things happening in our bodies, and we know even less about the mechanisms of moving, touching, speaking, seeing, or hearing, and so on.

As a scientist, I really cannot guess whether life scientists will ever be able to learn enough to solve the puzzles of the human body, but I feel a lack of satisfaction when the knowledge we have gained from scientific discoveries is compared with what is unknown. In my opinion this is why one of the most intelligent physicists in history, the Nobel laureate Richard Feynman, once said, “I was born not knowing, and have only had a little time to change that here and there” [1]. My understanding is that such a conclusion must be inevitable if the primitive knowledge given to us by modern sciences is not interpreted in the light of a far superior logic that is meant to explain the whole creation. In that sense, I believe that we have to consider every single detail in creation as a vital part of the whole in order not to feel lost before the grand picture of this masterpiece.

Last year, in a seminar at Osaka University Graduate School for Frontier BioSciences, I was thrilled to hear Professor Keichi Namba say, “Japan’s fastest supercomputer dissipates more than billion times the power dissipated by a fly’s brain, yet it is not able to simulate the brain of such a tiny animal.” This worked as a wakening call or a reminder for me to think again about the magnificent arts of the Creator. In particular, I wanted to revise my research on a hearing-related protein from a new perspective, rather than using the mechanical attitude that is followed most of the time.

This article is an attempt to explain an amazing mechanism in our ears that enables us to hear the faintest whispers. A mechanism that is switched off at loud cries to protect us from disturbing noises, yet amplified to make the softest sounds audible. Before starting to explain the basic anatomy of the human ear, I should mention that today the ear’s active amplification mechanism is still being investigated in research centers by biologists and physicists together.

How do we hear? What is happening in the inner ear?

Findings from the last century have shown that our ears are not just simple receivers as we had imagined. In 1979, David Kemp of University College, London discovered that mammalian ears can also emit sound vibrations. By placing a very sensitive microphone close to the eardrum he could detect whistles, implying that there is a source of vibration within the ear [2]. However, before trying to explain the cause of vibrations in the ears, we have to go over the mechanism of hearing briefly: The delicate design of the outer ear, the tympanic membrane (eardrum), and the tiny bones (malleus, incus and stapes) enables to collect sound waves traveling in the medium and transfer them to the inner ear (Figure 1a). In the inner ear the sound waves are sorted according to their frequency and amplitudes and then converted into electrical signals which can be transported to the brain via nerves. At the onset of this process the sound waves are transformed into standing waves on the basilar membrane which is laid along the organ resembling a snail, the cochlea (Figure 1b). The frequency of the incoming sound wave determines the positions of the distortions along the cochlea: High pitches create vibrations at the basal end of the cochlea (i.e. adjacent to the middle ear) whereas low frequencies vibrate closer to the apical end (Figure 1c) where the cochlea gets narrower. This geometry helps our ears to act as a frequency analyzer.

The efferent and afferent nerves that connect the ear to the central nervous system are attached to the organ of Corti, which is situated right next to the basilar membrane, extending over the cochlea. In other words, Corti is the sense organ of hearing, converting the motion of the basilar membrane into electrical signals that are conducted to the brain via neuronal cells [3]. The organ of Corti is also lined with multiple rows of sensory hair cells.

The hair cells of the organ of Corti

Corti is decorated with two different sets of sensory cells: single row of inner hair cells (IHCs) accompanied with 3–4 rows of outer hair cells (OHCs), both spanning the whole cochlear tube (Figure 2a). They are called “hair cells” because both IHCs and OHCs have typical bundles of stereocilia that contain mechanosensitive ion channels (Figure 2b).

The major function of IHCs is to detect the sound waves and then convert them into equivalent electrical signals that are to be interpreted by the brain. When the basilar membrane is perturbed by the incoming sound waves, the IHCs found in that region sense this activity by the movement of their hair bundles (bundles of stereocilia). The hair bundles of IHCs deflect and re-align as the basilar membrane moves up and down (Figure 3). We should note that this is an amazingly sensitive process such that deflections of the stereocilia on the order of a few nanometers (one millionth of a millimeter) can be detected and converted into nerve signals by the IHCs [4].

However, this by itself is not sufficient for hearing; no matter how effective IHCs work, the fluid that fills the cochlear tube is a threat to the sound waves traveling in the inner ear. In 1948, a young astrophysicist named Thomas Gold was the first person who has pointed out that the fluidic nature of the cochlea would dampen the sound vibrations and make them too weak to be detected by IHCs. He has concluded that an inherent vibration amplification mechanism is necessary in order to overcome such a problem [5]. Unfortunately, Gold’s statements were overlooked by the physiologists of his time who had performed their hearing related experiments on dead cochleas.

Gold’s predictions were justified around ten years later by William Rhode, a physiologist from University of Wisconsin, who has shown that the vibrations of the basilar membrane in live tissue samples are stronger than anticipated [6]. In the present day the existence of an amplification mechanism within a live cochlea is a well accepted fact. The only disagreement among scientists is about how the mechanism of the amplification works. Several scientific laboratories have reported different experiments performed on the organ of Corti and they have proposed different models. At the center of one of these models is prestin, a membrane protein which is not found in any cell but OHCs in the human body.

Electro-motile outer hair cells and prestin

In 1985, the distinctive properties of OHCs were first discovered by William Brownell, a University of Geneva neuroscientist, who has shown that these cells can convert electrical signals into motion: A phenomenon called electromotility. Electromotile OHCs can elongate or shrink in response to electrical charge density changes in their membranes. About a decade ago Peter Dallos and co-workers from Northwestern University in Chicago discovered a membrane protein, unique to OHCs, that can respond to electrical signals [3]. The Dallos group coined the name “prestin” for this protein in an analogy with the musical term “presto” (quickly) due to its rapid response to electrical signals. Various kinds of mammalian cells genetically engineered to produce prestin at their membranes displayed the electromotile responses that are very similar to OHCs.

According to Peter Dallos prestin protein works as a tiny machine which is a crucial element for cochlear amplification [7]. His theory is verified by recent studies which show that cochlear sensitivity in mice decreases hundredfold when prestin activity is disrupted by genetic means [8]. As the sound waves reach the inner ear, prestin-driven electromotility enables the OHCs to move like pistons. The piston movement in phase with the basilar membrane motion amplifies the vibrations and makes them stronger for IHC detection (Figure 4a,b). The prestin-driven vibrations were what Thomas Gold proposed and David Kemp had detected so many years ago. However, scientists are still searching and learning new things about this nanometer scale machine. One of the discoveries showed that prestin can adjust itself according to the amplitude of the incoming sound waves: Basically, the amplification is stronger when the sound waves are hard to hear but gets weaker as the volume increases.

Up to this point, we have briefly explained how the amplification mechanism of hearing in mammals works. Unfortunately, even though it took decades of research for scientists to discover and define the active nature of the mammalian ear, this explanation highlights only a minuscule part of the whole picture. That is why we are still incapable of curing most hearing problems. For example, hearing loss due to slightly disturbed hair cells with damaged stereocilia turns out to be chronic (Figure 5). The medical treatments we have to hand are too primitive to mend such delicate structures. Moreover, hearing aids made by today’s technology are not nearly as effective and functional as needed.

On the other hand, the delicacy of the hair cells and the limited control scientists have over them are not the only lessons we have learned from research on the inner ear. We cannot overlook the other messages attached to the research on the grounds that the time given to us is just too short to comprehend. It is an undeniable fact that the sense of hearing is designed in the best way to serve human beings. The different characteristics of hearing amplification at different sound levels make life much easier for us: Prestin-driven hearing is most effective when the sound waves are weak and harder to hear. This way the incoming sound waves are amplified enabling us to hear the faintest whispers. However, as the sound strength increases, the prestin-driven amplification gradually gets weaker and finally diminishes after a point to make sure that loud noises are less disturbing and hazardous for us. In my opinion, this amazing quality of a tiny protein found in our ears is one of the pieces of evidence that remind us of the necessity of pondering the favors of our Creator. Qur’anic verses such as Ibrahim 34 at the beginning of this article give us clues about how to interpret scientific findings that reveal the amazing qualities of our bodily organs. May the Creator of our ears allow us to reflect more on His favors and live accordingly.

Water has a vital role in maintaining the life of the cell. For example, 70% of the human body consists of water; also, approximately 70% of the earth is formed of water. Chemical reactions happening inside cells take place in liquid environments; in other words, life activities have been made to depend on water.

While water has such a vital importance for creatures, is there any living being that can live without water? The answer to this question is yes. For example, the African Lungfish (Protopterus), which is created with this special quality, can live without water for four years in hard times.

It is well-known that bears go into hibernation as a result of a God-given instinct during the winter cold. Storing necessary energy as fat in their bodies in order not to freeze, decreasing their body metabolism to the minimum rate, and being guided to choose a place to be protected from the cold during winter hibernation are important features bestowed on these living beings.

Another special features bestowed on some animals is the capacity for summer hibernation. This sleep is a marvelous quality that enables some animals to be able to live in hot and dry climates. Summer hibernation is the process of spending very hot summer days between sleep and lethargy in order to handle hard circumstances. A kind of silence is felt in the whole of nature during the extremely hot months of summer. This silence is caused by animals being in their summer sleep. Lungfish is one of those animals. There are various types of lungfish around the world: Queensland Lungfish (Neoceratodus forsteri), which is as long as 6 feet and which lives in the Burnett and Mary rivers in Australia; African Lungfish living Central Africa; 6 feet long Protopterus aethiopicus; 4 feet long P.dolloi; P. amphibious, which is written to be longer than 13 feet in some records; and Lepidosiren paradoxa living in South America.

Quite a lot is known about the summer sleep of the lungfish in Africa (Dipnoi). When the river water which flows from the treasures of God’s mercy is withdrawn during the summer months, the lungfish, which sink into wet clay by God-given instict, wait for a drawn back of water in a state of lethargy with having very low metabolisms. The fishes open a hole for themselves on the mud (down rivers and lakes) when rivers and lakes start to dry. When the mud goes into a drying process, specially featured mucous membrane that are put onto fishes’ skins start to work fast and fishes’ bodies are covered by a secreted mucus-like adhesive substance like a water-resistant cocoon. Fishes can stay alive by sleeping about 7-8 months during deadly summer hots with the amount of accumulated water inside cocoons. Although many fishes obtain the necessary oxygen through their gills, lungfish are created with an interesting special feature. The thin membrane bladders (gas bladders) that are responsible for regulating water level in other fishes are organized into a kind of breathing organ in the lungfishes by equipping with large amount of blood vessels in order to perform like lungs. God the Almighty can make different organs (analog organ) perform similar tasks as He does make similar organs (homolog organ) perform different tasks. None of these organs, which are created as the manifestation of God’s eternal knowledge and omnipotence, are characterized as being developed by their own through coincidental mutations. In contrast, every organ is created in the most appropriate character and capability to ensure maintenance of animals’ lives in the best way. Otherwise, we had to imagine those fishes that could know dry season with every aspects and that have the capacity and knowledge to change their organs as they want.

How do the fishes living in a water-resistant and durable cocoon obtain the necessary oxygen for themselves? The hole kept inside mud is used to get oxygen when oxygen inside cocoon reduced. The cocoon’s membrane made from mucus protects the little amount of water around the fish in mud but does not block the oxygen transition. While the dried mud works like a turbot against sun lights, the hole on the wall is kept. The lungfishes shrink around 1 inch during the summer sleep, since they use (burn) some of their fat and muscle tissue. When rains start and water fills lakes and rivers, the mud turbot that keeps lungfish dissolves; and the lungfish starts to continue its normal life in water.
