Class Forty Five in Section Four of Neshamos come

Neshamos are connected to Keilim (thought) (19). Ohr and Keli in three conditions: 1) After the Tzimtzum where the Ohr and Keli are altogether separated and then rejoined (to create worlds). 2) In עצם אור אין סוף where there isn’t even גילוי because in this level of אין סוף they are one ממש. 3) in the levels of Ohr before Tzimtzum where there is צמצום מיני’ה ובי’ה they are separated enough to affect גילוי even though they (Ohr and Keli) are not actually separated.
