79. This beating of left and right causes the partzuf to return to raising the feminine waters to the upper level244The conflict between the left and right lines (the left and right lines discussed in the earlier sections regarding the rectification of lines) means that the lower level does not receive any illumination from the upper level. As a result, it ascends again as feminine waters to trigger another change in the upper level, leading to the rectification of lines required for the illumination..
For the illumination of the left, which is the illumination of Ḥokhma,245See section 20 and subsequent sections for the in-depth discussion of the lines and their rectification. strikes and purifies all the opacity in the partzuf, until the partition returns to as pure a state as it was in the first time it ascended to the head of the upper level. That is, only the opacity of the root remains in it, and the remnant of enclothing of the first level, for by means of this equating it becomes attached to the head of the upper partzuf.
Then, after the partition is again incorporated in the fusion through collision of the upper head, the partition again receives a fusion through collision from the supernal light, on the opacity of the root and the first level of enclothing, which were renewed in the partition. The height of “three within three” again emerges upon the partition, which is the height of Ḥesed, Gevura and Tiferet that is enclothed within the height of Netzaḥ, Hod and Yesod, and which is called “the height of gestation” (as stated in section 75, above).246This process is a repetition of the process described above in section 75.
The phases of gestation, infancy and brains are duplicated. The final result is different in this second iteration, however, as will be explained. It has now been explained that the beating of the left upon the right, which occurred in the brains of the back,247See section 78 above and the footnote there for the explanation of this concept. caused the return of the lower partzuf to the upper partzuf to receive a renewed aspect of gestation from the upper partzuf.
