Qabalah and the Law of One.

[Henosis]

I would relate Tiferet to 4th density, Gevurah and Chesed to the 5th, Daath to 6th, with Binah and Chokmah related to the 7th.

Kether I would equate with the 8th, the Logos or the Divine Will.

If Kether represents the Great Central Sun, than Ohr Ein Sof would be the subtle energy at the heart of that Sun. So while Kether or the Logos appears to be the true Self, it still would not be a substantial Self as Kether or the Logos is nullified to the Infinite Light, which would be nullified to the Infinite itself, which within some philosophies would be nullified to Nothing or pure Unity.

Nothing (PERFECT UNITY) - Ayin
Intelligent Infinity - Ayin Soph
Infinite Awareness - Ohr Ayin Soph
Logos - Kether
