I think that those who serve most potently, work on levels of consciousness that have to do with radiating love — maybe God's love... It is important that you have a brain and use it, but that is secondary. The basic premise is that you allow something to come through you. Then you use your intelligence to give your heart's work discipline and logic. But the transformative energy, that which can change events, that heals, that helps, that serves, comes from somewhere deep inside.
Every night I had a sense to consciously pitch the tent of my being in a definite place of "unknowing." Bang in the pegs saying, I do not know anything. Inside the tent it might be dark, or maybe there were spins of moonlight. But in there, somehow or other, you know there is love. Love is, and may proceed from wherever you are, without you knowing anything very much.
