Question: The emptiness that we must find within us and fill, is this work with the ego?
Answer: Certainly. Emptiness is an egoistic desire that appears in me which I want to fill. These could be simple physical desires and they could be spiritual desires. With the spiritual desires this is slightly more complicated since I can never fulfill them by myself. And even the physical desires, basically, are only relatively fulfilled.
The idea is that I need to realize the spiritual desires that appear in me in someone else, to fulfill him, which is to say to transform “minus” into “plus.” A Kli is a very great negative desire or minus. I make a Tzimtzum (restriction) on it, the Masach (Screen), then the Ohr Hozer (Reflected Light), and in spite of this inner negative desire, I place someone else’s fulfillment above my desire. It follows that I transform the place where I feel emptiness into a mechanism for the fulfillment of the other or of the Creator, which in fact is the same thing.
