When it ascends, it ascends through Mother, which is the Aleph א of ADNY EQY”Q.
And upon Whom does it ascend? Upon the Middle Pillar, which is Vav ו – for it is wound around it, like a ring on a finger.
And it ascends in the Dalet ד of ADNY, which are the two arms and two thighs, until it ascends to the letter Yod י, which is Father, – Ḥokhmah, higher Yod – because it is from there that it is taken. It is this that is written: (Prov. 3:19) Y”Y in wisdom∞ḥokhmah has established the earth.
And it takes from the irrigating flow above, in its tip above, and in the middle, and its tip below.
