This is called the partzuf of the brains, for the first three lights, neshama, ḥaya and yeḥida, are called brains. For example, after Atik receives in a complete manner the two aspects of gestation and infancy, which are the heights of nefesh and ruaḥ, Atik returns and ascends as feminine waters to the head of Sag, and returns the Ḥokhma and Bina that are there to the state of face-to-face. Since the Bina that is in the partzuf of the Ḥokhma of Adam Kadmon is not intermingled with the Malkhut, therefore, when Atik receives this illumination it also brings down its own Malkhut from its own Bina.241The turning of Ḥokhma and Bina of Sag toward each other causes changes in the lower levels The exposure of lower level (Atik) to the illumination of the level of Sag of Adam Kadmon causes Malkhut to descend from the position it acquired in the level of Bina through the second constriction.
This is because lower levels are imprinted by and conform to higher levels. Since the second constriction only begins in the level of Nekudim, below Sag of Adam Kadmon, exposure to the illumination of that higher, unconstricted level causes the lower level to copy the higher one, undoing the constriction caused by the ascent of Malkhut to Bina. Then Atik raises the three vessels, its Bina, Tiferet and Malkhut, to its level, which fell due to the intermingling of Malkhut in Bina.242In the second constriction.
It now has Keter, Ḥokhma, Bina, Tiferet and Malkhut, of the vessels, in which the nefesh, ruaḥ, neshama, ḥaya, and yeḥida of the lights can be enclothed.
