Ohr has the opposite characteristics of Shefa: 1) It comes from the Source automatically, passively, and has nothing of the Source itself; 2) It has everything that the source has,
however there are two additional characteristics: 3) It is with Will, this means that if Hashem didn’t want Ohr it wouldn’t be. Nevertheless it is as if it is passively from the Sources. 4) In the Ohr the MaOr exists because of the MeAin HaMaor,
which means that there are three levels in Ohr MeAin HaMaor: 1) The Ein Sof light reveals, 2) the Yeshus which shows itself at the end of hishtalshelus, 3) Ideas in the MaOr which exist in Ohr that are never revealed in the world.
