69. The main element of the fusion through collision for the emergence of the lower partzuf is in the mystical meaning of a fusion through collision of the supernal light upon the partition, as stated above, since this determines the measure of the height of the lower partzuf, as is known. However, the awakening of the feminine waters188The ascent of feminine waters is a term referencing the “yearning” from below for the light of Ḥokhma represented by the ascent of Ze'er Anpin to the higher levels as the middle line.
In Kabbala and Torah thought generally, the concept of female denotes the dynamic of receiving, while male denotes giving. The flow of direct light of Ḥokhma from above to below is described as the “masculine waters.” of the lower one is also required, and this awakening is performed via the Keter and Ḥokhma of the lower partzuf that are attached to the Bina, Tiferet, and Malkhut of the upper one.189As was explained in the discussion of the rectification of lines, and the adjoining sections (section 20 and in subsequent sections), the Bina, Tiferet and Malkhut of an upper partzuf are ejected and join the Keter and Ḥokhma of the level below as a result of the second constriction.
The desire for the light of Ḥokhma in Keter and Ḥokhma of that lower level leads to a process in which the phase of maturity is initiated and Bina, Tiferet and Malkhut can return to their original, higher level. As this section explains, the Keter and Ḥokhma of the level below ascend with the Bina, Tiferet and Malkhut of the level above. This allows Ze'er Anpin to participate in the fusion through collision of the partzuf above Yisrael Sabba and Tevuna (as explained in section 65b). Consequently, both are necessary for the emergence of a lower partzuf.
