Part 1: Rooted in this Residue is everything that was destined to exist... This is obvious, because, as has already been explained, the Residue consists of what remained of the Primordial Light that departed through the Tzimtzum. For the Residue consists of all that was originally included in the Primordial Light as the root of the lower realms and beings. This remained in the Residue after the departure of all the other powers that were not part of the root of the lower realms and beings. Now, everything that was destined to exist in the lower realms was certainly originally included in the Primordial Light in the category of the root of the lower realms. If so, the Residue is the root of everything destined to exist in the lower realms.
