Rather, we should say that the Nekudim are not to be understood as a level on the scale leading to Atzilut. They are something different. The Nekudim correspond to the “flashes” and “sparks” mentioned by Rabbi Shimon bar Yochai (Zohar II, 254b). As the craftsman pounds the metal, the flashes and sparks are what separates from the body of the metal under the impact of the blow that comes to shape and fix the vessel. Following this metaphor, Atzilut is where the Supreme Mind took the underlying mystery of the Likeness of Man in order to establish it on its foundation, and the Supreme Mind then picked out what had to be removed and discarded from there. And what was it that had to be removed? Evil.
