When two vessels have developed in the partzuf, which are the two largest ones, that is, Keter and Ḥokhma, the light of ruaḥ also enters the partzuf and the light of nefesh then descends from the vessel of Keter to the vessel of Ḥokhma, and the light of ruaḥ is enclothed in the vessel of Keter.
In this manner, when a third vessel has developed in the partzuf, which is the vessel of Bina, the light of neshama enters the partzuf, and then the light of nefesh descends from the vessel of Ḥokhma to the vessel of Bina, the light of ruaḥ leaves the vessel of Keter and enters the vessel of Ḥokhma, and the light of neshama is then enclothed in the vessel of Keter.
