Ain becomes Ain Soph, and even further becomes Ain Soph Aur ; which then by contraction (Which is known as Tizimtzum according the the Zohar) concentrated itself into the central formless point-Kether translates as Crown, which is the first sephirah on the tree of life. In Luranic Kabbalah, the explanation of Tizimtzum is a process of creation by God “contracting” his Ain Soph Aur in order to allow a “conceptual space” in which finite and independent realms could exist.
Kether is the one, whose center is everywhere and whose circumference is nowhere. Kether is the Monad which is a term used by Neo-Platonists to signify the One. Kether’s Egyptian equivalent is Ptah, the creator of the cosmic egg or Amun-Ra the king of the gods. The Greek equivalent is Zeus and Roman Jupiter, the lord of heaven. In Hinduism Kether is Brahma the creator aspect, from whom sprung the seven Prajapati that correlate with the last 7 Sephirot. It is the root of all things and the ultimate unit of consciousness, as a metaphysical point and centre of spiritual phenomena. This seperah is unextended and indivisible and is the prototype of everything spiritual and everything else in the cosmos. In a simple sense, It is the essence of being, the essence of Spirit coming into Matter, and the highest attribute of God.
