We start with Keter, the crown. It can be recognized as the “first thing”. It is the “I AM”, the point in the circle, the Holy Number “1”.
We cannot deny the fact of our own existence, or of at least –something- which perpetuates our existence, call it Mind or what we Will. Being, the state of existence, is beyond all doubt – however, we do not know the reason for this existence. Although we cannot comprehend the reason for this existence, we still exist none the less.
Keter is the Source of Existence - of all things on all planes, manifest and unmanifest, within the macrocosmic universe and the microcosmic man. It is the SELF-EXISTENT CROWN of BEING.
Keter-as-Emanation is described in the Zohar, in "P'Tach Eliahu," where, addressing the Creator, Eliahu the Prophet says: "...[You are the] Orach Atzilut, the Path of Spiritual Emanation, which irrigates the tree of the Sefirot with its arms and branches, like water that irrigates a tree causing it to grow thanks to that irrigation. Master of the Universe, You are the Primary Cause, and Producer of Results, Who irrigates the tree through the spring of prophecy. That spring is like the soul to the body, in that it gives life to the body."
An important quality of Keter that should be carefully considered is that it is not capable of comprehension, nor is it capable of realizing its own nature. It just is.
It is the act of Reflection, of Comprehension, or Self-Recognition which brings forth the first duality of Wisdom (Chokmah) and Understanding (Binah).
1 ......... Keter (Crown). This is the place of unconditional existence which may be identified with the highest state of consciousness. In Keter, all is one. Keter is the highest of the four Sephiroth that form the middle pillar of the Tree of Life. This middle pillar is a series of graduated levels of balanced consciousness reaching from the purely physical to the purely spiritual. The two pillars to the right and left contain unbalanced states of consciousness which display either too much emotion or too much rationality. Only the middle pillar is a comfortable place to reside.
