...only in the mystery of the garments of Atzilut, these being Beriyah, Yetzirah and Asiyah. This tells us two things:
(1) In the human form – the Likeness of Man – the thing that is most external is the clothing. The same applies up above. Morever, the clothing is not a part of the person’s intrinsic essence but merely what he wishes to dress himself in. Similarly up above, the essence of the lights lies in Atzilut, whereas Beriyah, Yetzirah and Asiyah are the garments in which the light wants to clothe itself, and the garb is considered incidental to the actual lights, which are the essence. Evil exists only on account of the garments and does not derive from the essence of the lights themselves but only from the garments in which the lights want to be clothed. Aside from these garments, they contain no darkness or flaw at all.
