Part 1: Zeir Anpin and Nukva grow to maturity together… Zeir Anpin and Nukva are two separate Partzufim each with their own unique arrangements in accordance with their respective roles. (The unique repairs of Zeir Anpin are successively higher levels of Mental Powers, while those of the Nukva – separation, נסירה, nesirah, lit. “sawing” and the various states of face-to-face, back-to-back etc. – prepare her for coupling.) Nevertheless, one common aspect is that throughout the entire time of the building of Zeir Anpin, Nukva is with him.
