021 Yom Tov Shel Rosh Hashana (יום טוב של ראש השנה) 5666 (In Depth Version) – Class 21

21. Yom Tov Shel Rosh Hashana Samech Vov; Third Round, Class Twenty One.
Continued, affect of first Tzimtzum.
Tzimtzum’s affect on Ohr continued.
It separates the (so called) חיצוניות האור from the פנימיות האור; the Pnimiyus becomes עיגול hidden, which we call נגע בו הצמצום (touched by the Tzimtzum).
The חיצוניות האור is actually changed by the Tzimtzum (not only ‘touched’ by it); as it needs to burst through the darkness of the Tzimtzum itself, which causes it to change categorically from עיגול to יושר (which allows it to go into Vessels and adapt still further).
