We therefore call this light that is revealed in the Residue after the Tzimtzum “Malchut”, and we say that it is like the last part of all that departed, which we have compared to the nine higher Sefirot. Accordingly we call it a Residue of all that departed.
We must distinguish between two different aspects here. The bond of these parts, namely the law that the lower realms should exist – this being the overall Malchut in its proper place – we will term the Place or Space of the lower realms. This is the power that gives a place for their existence. But inasmuch as the overall Malchut is built of the residue of all that departed and includes the power contained in each Sefirah to bring forth the lower realms, we can term this the actual root of the lower realms.
