Zeir Anpin is an upper mechanism. Whereas Malchut is my system that I can build together with the friends, that is, with the desires of the Creator that He arranges for me so that I can connect with them.
There are types of desires that do not belong to me; they are foreign desires, but they are also aimed at the Creator like me. I don’t look at their faces but only at the desires, or sparks.
Then I perform different external actions in order to unite us. I want to collect all these desires, all these small vectors into one bundle so that they will become powerful. When they are together, it’s impossible to break them as it is when they are separate.
We connect when each one annuls himself in order to attain the greatness of the Creator, the greatness of the attribute of mutual bestowal. We create it among us in order to show ourselves and the Creator that we are ready for bestowal and want it. Although it isn’t in our power to attain it and we can’t really bestow upon each other by annulling our ego, we still show the most we can reach in our group.
If we make such efforts, the Light that Reforms appears and fulfills the connection among us. Then from this connection (Malchut), we feel the attribute of bestowal that connects us with Zeir Anpin. Thus we discover the Creator: Yesod of Zeir Anpin connects to Malchut and Malchut begins to attain Him.
Malchut doesn’t connect to Zeir Anpin only by a point any more. It begins to open the attributes of bestowal inside it, which befit Zeir Anpin and at the same time are opposite from it because they cooperate with each other. Zeir Anpin and Malchut connect so that the upper Light is revealed between them: the Light of Hochma and Bina, the Light of AB-SAG, and thus we come to consciousness.
Everything depends on how we prepared Malchut. Accordingly, as much as a desire suitable for Zeir Anpin appears in it, it begins to grow together with Malchut. It absorbs its desire and thus grows.
