MAN is translated as Mei Nukvin (female waters), which means that in a prayer there should be two elements: Malchut and Bina. Maim (water) is Bina, and the female attribute is Malchut. Only then is it called raising a prayer, MAN.
If I just feel sorry for feeling bad, it is only Malchut. The question is what should I feel sorry about, who should I turn to, what do I want to receive? There must be a clear picture of this request that ties Malchut to Bina: the desire and its direction. I have to understand to whom my sorrow and my pain are directed. Perhaps I simply feel sorry because I am in a bad mood, but that is not considered a prayer, raising MAN.
If I feel bad because the Creator is concealed, and I don’t feel the importance of the spiritual advancement, don’t want to come to the lesson but would rather sleep, it isn’t raising MAN, a prayer. It is simply a feeling of emptiness in my egoistic desires.
Everything depends on what I want, what I’m sorry about—Who I am sorry for. This means that the reason for my sorrow has to be external to me. Then I form my MAN by these two dissatisfactions, these two Malchut: the Malchut of Bina and Malchut of Malchut. A prayer has to be directed accurately.
