This is the key to understanding the Sefirot as they appear within the Residue. The Sefirot constitute the governmental order of reward and punishment, and were made in accordance with the concealment of perfection. It is because of this that the flaws and defects exist in actuality, since they are contingent on the fact that the government is subject to the rule of strict judgment, and the bestowal of good hangs in the balance because there is a barrier which impedes it. This is not so in the case of perfection, which has no impediment whatever.
