Just as the 'I' is the key to the Divine Names, which are hidden treasures, so is it the key to the locked talisman of creation; it is a problem-solving riddle, a wondrous talisman. When its nature is known, both the 'I' itself, that strange riddle, that amazing talisman, is disclosed, and it discloses the talisman of the universe and the treasures of the Necessary World. We have discussed this problem as follows in my Arabic treatise, Şemme (Intimations).
The key to the world is in the hand of man and is attached to his self. For while being apparently open, the doors of the universe are in fact closed. God Almighty has given to man by way of a Trust, such a key, called the 'I', that it opens all the doors of the world; He has given him an enigmatic 'I' with which he may discover the hidden treasures of the Creator of the universe. But the 'I' is also an extremely complicated riddle and a talisman that is difficult to solve. When its true nature and the purpose of its creation are known, as it is itself solved, so will be the universe.
The All-Wise Maker gave to man as a Trust an 'I' which comprises indications and samples that show and cause to recognize the truths of the attributes and functions of His dominicality, so that the T might be a unit of measurement and the attributes of dominicality and functions of Divinity might be known. However, it is not necessary for a unit of measurement to have actual existence; like hypothetical lines in geometry, a unit of measurement may be formed by hypothesis and supposition. It is not necessary for its actual existence to be established by concrete knowledge and proofs.
Question: Why is knowledge of the attributes and Names of God Almighty connected to the 'I'?
The Answer: Since an absolute and all-encompassing thing has no limits or end, neither may a shape be given to it, nor may a form be conferred on it, nor may it be determined; what its quiddity is may not be comprehended. For example, an endless light without darkness may not be known or perceived. But if a line of real or imaginary darkness is drawn, then it becomes known. Thus, since God Almighty's attributes like knowledge and power, and Names like All-Wise and All-Compassionate are all-encompassing, limitless, and without like, they may not be determined, and what they are may not be known or perceived. Therefore, since they do not have limits or an actual end, it is necessary to draw a hypothetical and imaginary limit. The 'I' does this. It imagines in itself a fictitious dominicality, ownership, power, and knowledge: it draws a line. By doing this it places an imaginary limit on the all-encompassing attributes, saying, "Up to here, mine, after that, His;" it makes a division. With the tiny units of measurement in itself, it slowly understands the true nature of the attributes.
