They think self-surrender means to say, “I have no mind. I have no heart. I only believe and follow, for I am nothing.”
This is not self-surrender—this is denial of the truth. For it is saying there is a place where G–dliness cannot be—namely your mind and your heart.
G‑d did not give you a brain that you should abandon it, or a personality that you should ignore it. These are the building materials from which you may forge a sanctuary for Him, to bring the Divine Presence into the physical realm.
Don’t run from the self with which G‑d has entrusted you. Connect your entire being to its Essential Source. Permeate every cell with the light of self-surrender.
