The reason for their division is as follows: In each and every partzuf in Atzilut there are two types of vessels: (1) vessels that emerged in the world of Atzilut through a fusion through collision, and these are called “vessels of Mah,” and (2) vessels that broke in the world of Nekudim, which are called “vessels of Ban.”140The “breaking of the vessels” is a complex process that ultimately gives rise to the world of tikkun (rectification), which is the world of Atzilut and downward.
As this section describes, these broken vessels, from the world of Nekudim, descended to a low level, then were “salvaged” and served as a pairing component for the partzufim structures of Atzilut formed through the fusion through collision against the partition. These are rectified and ascend from Beria, Yetzira, and Asiya and connect to the levels that emerged through a fusion through collision in the world of Atzilut, which is called Mah.
The vessels of Mah are considered male, while the vessels of Ban are considered female. Consequently, there are male and female components in each partzuf from Atzilut and downward.
