“In order to leave no traces, when you do something, you should just do it with your whole body and mind: you should be concentrated on what you do, You should do it completely, like a good bonfire. You should not be a smoky fire. You should burn yourself completely, like a good bonfire. If you do not burn yourself completely, a trace of yourself will be left in what you do. You will have something remaining which is not completely burned out.”
