The whole life of the mystic is mapped on this principle, and it is by this principle that he can arrive at the stage where his impulse becomes a voice from within that tells him "go here", "go there", or "leave", "move", or "stay." Therefore while others are prepared to explain why they are doing something or going somewhere or what they wish to do, the mystic cannot explain, because he himself does not know. And yet he knows more than the person who is ready to answer why he is going and what he is going to accomplish, for what does man know about what will happen to him? He makes his program and plans, but he does not know.
