Once, after a particularly inspiring class in which we covered a hell of a lot of new material, I told my teacher that there was no way I would remember most of what we did. His advice: "Go home, forget all about this class and do your practice as usual. If what we did here today has any truth and value then it'll find its way in despite you, not because of you." And sure enough, that's exactly what happened, but only because he taught with energy and spirit, not with body and technique.
