Of course. We only quote Kabbalists. Rambam was a great Kabbalist. His writings aren’t adapted for our generation, Baal HaSulam is the adapter, which is why they advance us when integrated in Baal HaSulam’s writings. Rambam’s writings on their own, it’s questionable how much they can advance us.
These are reasonable assumptions according to what we feel, but no, the Creator doesn’t have a desire. He is the quality of bestowal. But if you want, you can think that He has a will to bestow, but his deficiency is in others, only that they will be fulfilled, and He gets contentment when the good goes entirely to the other.
Our world is not yet Assiya. We have a Point in the Heart, and only that is considered the Achor be Achor (backside of the backside) of the first degree of the spiritual world.
