As for the words, “And Hashem smelled the sweet savor (lit. fragrant scent),” the fragrance indicates twice the satisfaction on both sides, right and left. The one on the right is the satisfaction revealed from the most hidden Atika Kadisha; it is satisfaction and exuberance for everyone, both for Chochmah and to Chassadim. The one on the left refers to exuberance coming from below, that is, from the curtain of Chirik that people raise with the smoke and fire from the altar (as in section 126A), because it is made better by both sides – by Atika and from below. It is therefore written, fragrance (nichoach), which is twice the satisfaction (nachat). And it all refers to Zeir Anpin.
