Note 64 — Chapter VII · THE HOLY KABALAH
Arthur Edward Waite translation
All later Kabalists agree that Tetragrammaton is the root and foundation of the Divine Names. In the Sephirotic system one of the allocations makes Chokmah, or Supernal Wisdom, to correspond with the Yod of Tetragrammaton. Kether, which is the Crown, is said to have no letter attributed thereto, because the mystery of Ain Soph, the hidden abyss of the Godhead, is implied therein. However, the apex of Yod does in a sense intimate concerning Kether. He is the second letter in the Divine Tetrad, and it is ascribed to Binah, or Supernal Understanding, wherein is all life comprehended. This is the abode of the Shekinah in transcendence. The third letter is Vau, and it is said to contain the six Sephiroth from Chesed to Yesod. The second He is the fourth and last letter; it corresponds to Malkuth, or the Kingdom, wherein is the mystery of the unity of God. This is the abode of the Shekinah in manifestation. Thus, Yod, He, Vau, He, which we render Jehovah, contains all the ten Sephiroth. There are, however, other allocations.
