…with no further subdivision… When Abba and Imma themselves give Zeir Anpin his mental powers (i.e. in the Second Maturity), there is no need for Israel Sabba-Tevunah to divide into a separate Partzuf by themselves. Rather, they are considered as merely Malchut of Abba and Imma – for they are only called an independent Partzuf when they are the primary agent in giving the Mental Powers, because they are then given power in their own right. And thus:
…their Malchut clothes itself in Zeir Anpin’s Tzelem, and the lowest part of this Malchut becomes interior in Zeir Anpin while the two upper parts are encompassing levels. Israel Sabba-Tevunah are then considered as Abba and Imma’s Malchut, which itself divides up into Ten Sefirot until it becomes clothed in all of the Tzelem. It is clothed therein as explained in connection with the mystery of the Tzaddi, the Lamed and the Mem (see Opening 127). This is called the First Israel Sabba-Tevunah.
