Part 9 · Chapter 4

And the souls of the righteous that are drawn from Atzilut are the sons of ZON [Zeir Anpin and Nukva], who raise MAN [Mayin Nukvin] to them. In this same way, the souls of the righteous drawn from Beria are those who raise MAN in Beria; and the Ruchot [spirits] of the righteous, in Yetzira; and the Nefashot, in Assiya. The end of the matter: there is no Zivug [coupling] in the world except through the raising of MAN by their sons, after they have been corrected once at the creation of the world — each and every one in its own degree.
