kindsephirah
divine name— (a confluence of the names above it)
archangel— (traditions place the united archangels, or none, here)
heavenly sphere— (some modern schools: Sirius; tradition: none)
in the bodyThe nape; the throat of Adam Kadmon
soul levelThe knot binding Chayah and Neshamah
Not a sephirah and yet unmistakably there: Da'at is the knowledge where Wisdom and Understanding actually join — "And Adam knew Eve" uses this word. On the Tree it marks the abyss between the supernal three and the lower seven; when the Tree is counted with Da'at, Keter withdraws, for "Keter and Da'at are one from different sides." In Chabad thought Chokhmah-Binah-Da'at (ChaBaD) form the intellect whose union births every emotion below.
The Zohar treats Da'at as the hidden key of the middle pillar — the breath that moves between Father and Mother and fills the six chambers below.
