...and therefore did not escape the sadness and angry faces... Strict Judgment stood in its full force. Here we can see clearly how man’s service brings about repair. Since the only purpose of strict Judgment is to withhold His influence from the lower creations during the time when they are not prepared, there is no other remedy except that the lower creations should be ready, and then He will send blessing. Accordingly, as long as the Nukva is not prepared, sadness reigns and this is what prevents the lights from shining since they do not reveal their goodness at all unless there is a vessel ready to receive them.
Strict Judgment Cries Out to God
Kalach Pitchei Chokhmah 52:27
