The Qabbalists conceive of the Supreme Deity as an Incomprehensible Principle to be discovered only through the process of eliminating, in order, all its cognizable attributes. That which remains —when every knowable thing has been removed— is AIN SOPH, the eternal state of Being. Although indefinable, the Absolute permeates all space. Abstract to the degree of inconceivability, AIN SOPH is the unconditioned state of all things. Substances, essences, and intelligences are manifested out of the inscrutability of AIN SOPH, but the Absolute itself is without substance, essence, or intelligence. AIN SOPH may be likened to a great field of rich earth out of which rises a myriad of plants, each different in color, formation, and fragrance, yet each with its roots in the same dark loam which, however, is unlike any of the forms nurtured by it. The "plants" are universes, gods, and man, all nourished by AIN SOPH and all with their source in one definitionless essence; all with their spirits, souls, and bodies fashioned from this essence, and doomed, like the plant, to return to the black ground —AIN SOPH, the only Immortal— whence they came.
AIN SOPH was referred to by the Qabbalists as The Most Ancient of all the Ancients. It was always considered as sexless. Its symbol was a closed eye. While it may be truly said of AIN SOPH that to define It is to defile It, the Rabbis postulated certain theories regarding the manner in which AIN SOPH projected creations out of Itself, and they also assigned to this Absolute Not-Being certain symbols as being descriptive, in part at least, of Its powers. The nature of AIN SOPH they symbolize by a circle, itself emblematic of eternity. This hypothetical circle encloses a dimensionless area of incomprehensible life, and the circular boundary of this life is abstract and measureless infinity. According to this concept, God is not only a Center but also Area.
Centralization is the first step towards limitation. Therefore, centers which form in the substances of AIN SOPH are finite because they are predestined to dissolution back into the Cause of themselves, while AIN SOPH Itself is infinite because It is the ultimate condition of all things. The circular shape given to AIN SOPH signifies that space is hypothetically enclosed within a great crystal-like globe, outside of which there is nothing, not even a vacuum. Within this globe —symbolic of AIN SOPH— creation and dissolution take place.
Every element and principle that will ever be used in the eternities of Kosmic birth, growth, and decay is within the transparent substances of this intangible sphere. It is the Kosmic Egg which is not broken till the great day "Be With Us", which is the end of the Cycle of Necessity, when all things return to their ultimate cause. In the process of creation the diffused life of AIN SOPH retires from the circumference to the center of the circle and establishes a point, which is the first manifesting One —the primitive limitation of the all-pervading O.
When the Divine Essence thus retires from the circular boundary to the center, It leaves behind the Abyss, or, as the Qabbalists term it, the Great Privation. Thus, in AIN SOPH is established a twofold condition where previously had existed but one. The first condition is the central point--the primitive objectified radiance of the eternal, subjectified life. About this radiance is darkness caused by the deprivation of the life which is drawn to the center to create the first point, or universal germ. The universal AIN SOPH, therefore, no longer shines through space, but rather upon space from an established first point. Isaac Myer describes this process as follows: "The Ain Soph at first was filling All and then made an absolute concentration into Itself which produced the Abyss, Deep, or Space, the Aveer Qadmon or Primitive Air, the Azoth; but this is not considered in the Qabbalah as a perfect void or vacuum, a perfectly empty Space, but is thought of as the Waters or Crystalline Chaotic Sea, in which was a certain degree of Light inferior to that by which all the created worlds and hierarchies were made".
In the secret teachings of the Qabbalah it is taught that man's body is enveloped in an ovoid of bubble-like iridescence, which is called the Auric Egg. This is the causal sphere of man. It bears the same relationship to man's physical body that the globe of AIN SOPH bears to Its created universes. In fact, this Auric Egg is the AIN SOPH sphere of the entity called man. In reality, therefore, the supreme consciousness of man is in this aura, which extends in all directions and completely encircles his lower bodies. As the consciousness in the Kosmic Egg is withdrawn into a central point, which is then called God —the Supreme One— so the consciousness in the Auric Egg of man is concentrated, thereby causing the establishment of a point of consciousness called the Ego. As the universes in Nature are formed from powers latent in the Kosmic Egg, so everything used by man in all his incarnations throughout the kingdoms of Nature is drawn from the latent powers within his Auric Egg. Man never passes from this egg; it remains even after death. His births, deaths, and rebirths all take place within it, and it cannot be broken until the lesser day "Be With Us," when mankind —like the universe— is liberated from the Wheel of Necessity.
