Some of the Partzufim are male and some are female. That is, some of them channel Kindness and some Judgment. Through their coupling, the flows are joined together, giving birth to the necessary action. For there is nothing that does not have the agreement of the two qualities of Kindness and Judgment. And there are certain differences in the lights of the male and female as well as a real difference in their law of operation. But as regards any difference in form – any real difference – this is found only in the lights that are involved in the channeling, namely the Yesods, for these are the ones that perform the channeling, and all the different parts of the Partzuf are drawn to them to flow forth in accordance with their law.
