In a place of lack, the abundance does not shine because there is a place of reception called “separation.” But if it does not leave abundance because it does not need, since it is in above reason, called “desiring mercy,” there is no place for judgments because no deficiency is evident, so there is no place for the grip of the Sitra Achra [other side]. This is called “the world of correction,” for everyone to be connected.
