...out of which He produced the entire Tree of Holiness. It was necessary for the governmental order to consist of two things joined together: deficiency on the one hand and the complete perfection that repairs it on the other. For all this successively makes known God’s unity. (Without the preceding deficiency, there would be no revelation of the unity.)
Thus the Supreme Mind set to work making all that it made through this repair, until all the different levels and Partzufim were produced, all constructed out of parts damaged in the earlier destruction together with the repair that came to fix them (the parts of MaH and BaN from which the Partzufim were made). It is in this mode that the world is now governed, and now the completion of this repair in all its details is in the hands of man.
