The bringing forth of something into existence ex nihilo, yesh me’ayin, is known as Beria (Creation). Since the opacity (ovyut) in the vessels cannot be revealed in the world of Atzilut (Emanation), but only from the ground of the world of Atzilut (Emanation) and below, it is therefore called Beria from that point and below, after the opacity (ovyut) that has been revealed. For the opacity (ovyut), which is comprised of the will to receive in the created being, is a form of yesh me’ayin, creation from nothing. Everything that exists is drawn from God as yesh miyesh, literally “something from something,” because there is nothing He does not have, apart from a “will of receiving,” which of necessity He does not possess, since there is no one from whom He could receive, God forbid. This must be understood.
