The basis for all my explanations is the desire to receive, which is imprinted in every creature, which is the difference in form from the Creator.

All the wisdom of Kabbalah deals only with what separates us from the Creator, which is the desire to receive, and how and to what extent we are far from Him, and in what way we can reunite with Him...
