However, Malkhut subsequently partnered with the attribute of mercy, meaning in Bina, so that due to Malkhut partnering with Bina, Ze’er Anpin and Nukba are fit to receive brains, namely, the illumination of Ḥokhma. We call this Malkhut that partners with Bina “maftaḥa” (key) (as stated above in Sulam on the introduction to the Zohar 57, s.v. “hahu”).
Therefore, these two forces, manula and maftaḥa, are also present in the partition of Ze’er Anpin, which is the middle line.58After the second constriction, Malkhut operates in two roles. It serves as a terminating element at the bottom of a set of sefirot (the terminating Malkhut, with a partition associated with the manula mentioned here). It also serves as a channeling factor when it pairs with Bina, ultimately allowing the flow of the light of Ḥokhma to reach lower levels of existence (with a partition of maftaḥa). Initially, when Ze’er Anpin needs to reduce the first three of the left line, it does this using the partition of manula, which is the Malkhut of the attribute of judgment, because wherever this Malkhut reveals itself, the supernal light flees from there (as explained in Sulam, Vayetzei 13, s.v. “sitra”). However, since Ze’er Anpin wants to compel the six extremities of Ḥokhma to remain, it subsequently conceals this partition of manula and operates with the partition of maftaḥa, which is the Malkhut that partners with Bina. Through its power, the illumination of the six extremities of Ḥokhma remains (see also Sulam, Lekh Lekha 13, s.v. “venitba’er”).
