This is what was lacking in the Primordial Kings, for the Six Directions were not turned towards Malchut and therefore did not escape the sadness and angry faces, and Imma still allowed them to remain that way. Accordingly, the first three Sefirot of Zeir Anpin were missing, for these result from Imma’s entry into and repair of Zeir Anpin. The others were then termed the domain of the many (רשות הרבים, reshut harabim), and this was the state from which the Other Side emerged, which is why its nature and function are only to cause separation.
