Literally meaning to separate, abstract, peel away, or to isolate oneself from every occupation and engagement, tajrid (isolation) denotes the state where one isolates oneself from worldly things and abandons all carnal or bodily desires. It also denotes turning away from all else save God and being freed from any attachment to wealth, status or position or any worldly expectations, and setting one’s heart totally on Him without expecting anything in return.

The scholars relate isolation to the Qur’anic statement, Take off your shoes (20:12), and interpret this as the purifying of the heart, which they call the home of God, of all worldly and otherworldly considerations, and preparing it for the visit of the All-Holy Sovereign. Some go a step further and regard this as turning to the Light of Lights with all one’s heart and setting one’s heart totally on Him without leaving any room for anything else in one’s feelings, according to one’s capacity. From another perspective, isolation has been approached as resistance against all carnal or bodily appetites and impulses and against the attractions of the world with whatever is in it. Initiates who have not been able to isolate themselves from carnal appetites, the attractions of the world, the attachment of the heart to anything else save Him, or from any worldly or otherworldly consideration, cannot attain His private company and the spiritual pleasure inherent in this.

Concerning this significant point, the author of al-Minhaj

says:

So long as you do not isolate yourself
from considerations about everything save Him,
You will not be able to reach privacy
with the Beloved in His private room.

Ibrahim Haqqi expresses the same point, as follows:

The heart is the home of God;
purify it of whatever is there other than Him,
So that the All-Merciful may descend into His palace at nights.

Isolation, which, in the words of Sayyid Sharif [1], is cleaning the heart and other innermost faculties from the dirt and dust of attachment to anything save Him, requires that the people favored with a vision of Him should isolate themselves from whatever they see or hear, and that they live immersed in the lights of the Existence of the Eternal Witness. Every initiate feels this and is favored with its gifts according to the individual’s capacity.

When those who are in the initial stages of the spiritual journey find themselves growing in the knowledge of God that is developing in the heart, the information acquired concerning Him gradually fades, and they begin to receive glimpses from beyond things. Then all of their material or bodily necessities, and even the entire world with whatever is in it, gradually lose their importance and value for them and they become polished mirrors to the truth, or function as some misty medium to reflect Him. One who feels this favor sometimes says, like Fuduli,

The way of isolation is a home
requiring full renunciation and sacrifice to settle in,
so abandon whatever worldly things you have,
and do not have a house.

or sometimes cries, like Yunus Emre:

I have found the unique, matchless honey;
Let everybody come and plunder my existence.

One who has reached the final point of the spiritual journey is freed from all considerations concerning other existent beings save God, and is left with no trace that belongs to anything else except Him. If those favored with this degree of isolation do not follow the principles of the Prophetic way or the rules of Shari‘a in their considerations, they may lapse into negating the “reality of things”— the established originals or essences of things in God’s Knowledge. This is a rank where many initiates live in a daze. Whereas, those who strictly follow the signposts and lights of the Prophetic way during their entire journey, though admitting the reality of things, see in everything only He Who is the One, only know the One, only mention the One, only call the One, and only turn to the One in thousands of signs of “dawn,” turning their eyes from all others.

Ahmedi [2] describes this rank according to his feeling as follows:

I have submitted all my being to that Friend, having no home any longer;
And purified my hands of any worldly things I had, being left without both of the two worlds.
For God’s love has come and drawn me to itself: opening the eyes of my heart, awakening me from an intoxicated sleep.
His Unity has become manifest to me, so that I have seen Him with all certainty.
I have driven away polytheism, having no doubt any longer.

As for the state of those who have completed their journey toward God, it is such a deep, indescribable state of pleasure, where efforts toward isolation have ended in perfect isolation and they have all but lost their own being, that those who do not experience it cannot know or describe it. Anybody who attempts to describe it cannot be saved from confusion. Such a relation between the Almighty, Ultimate Truth and an initiate whom He has favored with such a degree of spiritual attainment must be a mysterious gift of secrecy of His to His distinguished servants. What we should do is to feel respect for this gift of secrecy.

O God! Show us the truth as being true and enable us to follow it, and show us falsehood as being false and enable us to refrain from it. And bestow blessings and peace on our master Muhammad, the guide to the truth, and on his Family and Companions, godly, noble and honorable.

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.
