It could be objected that we said above (Opening 61) that MaH chooses what is suitable from BaN, whereas here we are saying that it is in BaN that the process of selection takes place, and that the descent of MaH depends on BaN. The answer is that it is indeed true that this arrangement of MaH and BaN was made at the outset – which part of each was suited to which part of the other – and it was MaH that made the selection in accordance with MaH’s intrinsic nature.
This was accomplished through the mystery of the drop of Adam Kadmon’s Male Waters that sweetened the Primordial Kings, as stated above, in accordance with the mystery of Yesod of Adam Kadmon that sweetened Malchut. From this foundation there subsequently emerged the Head that is not Known (רישא דלא אתידע, Reisha delo ityeda), as will be discussed later. Afterwards the overall Nukva went through the process of selecting what was suitable in accordance with the original supreme division that I have discussed earlier. (In other words, initially MaH went through the process of selecting what could be repaired, with MaH providing the material for the repair – the Male Waters.
Afterwards the Nukva correspondingly goes through the process of actually selecting what is fit to be repaired out of the breakage. The overall selection by MaH follows the pathways of the world of reward – the Head that is not Known, while the actual selection is carried out through the Nukva by means of the service of the lower creations.)
