ה Hei = is the Ain Soph, the uncreated light (Aur), the first breath from the absolute that through Yod (Kether, the First Logos, First Word) becomes הא Hah (Kether, Chokmah, Binah, the Logoic triangle in Atziluth), the breath before all uttered letters.
י the isolated Iod is therefore Kether, and א Aleph is Kether, Chokmah, Binah, the Logoic triangle in Atziluth, and ה Hei is the Ain Soph, the breath that manifest in the infinite through Kether.
יה Jah is also Kether, the Divine Androgynism, that manifests through Binah, the Holy Spirit (י Iod Abba and ה Hei Aima Elohim). Hallelujah.
Thus shalt thou say unto (all the letters, namely,) the children (or Archetypes) of Israel, I Become (אהיה Eheieh Kether) hath sent me unto you. – Exodus 3: 14
Weep not: behold, the Lion of the tribe of Judah,
the Root of David, has prevailed to open the book,
and to loose the seven seals thereof. - Revelation 5: 5
