The entire desire of the Male that is Zeir Anpin for the Female lies here in Zion. It is called a blessing, since blessings come out from there to all the realms and everyone is blessed. This place, Zion, is called holy. And all the holies, that is, the holy lights of the Male, which is Zeir Anpin, penetrate there the level I spoke of, namely, Zion.
And they all come from the top of the head of the male skull, that is, from the first three Sfirot of Chayah of Zeir Anpin, from the part of the highest brains that reside in it. And that blessing flows from the brain lobes to all body parts that are Chesed, Gvurah and Tiferet down to those called hosts that are Netzach and Hod. All the abundance that flows from the entire torso is gathered there in Netzach and Hod, which is why they are called hosts: all the higher and lower hosts in the three realms of Briah, Yetzirah and Asiyah derive from Netzach and Hod.
They place it in the holy Yesod, which is wholly white, which is why it is called Chesed. And that Chesed enters the Holy of Holies as written, “for there Hashem has commanded the blessing, even light for evermore.”
