The way that I think about this is that the teacher brings the student information which I liken to food. Then the student digests the information and uses it to create music. But, the student cannot be passive. He must take that information; he must use what he deems to be useful and discard which he cannot use. Too many people think that they can learn passively, as if it is the teacher's job to make the student learn and become proficient. It doesn't work that way and if we can become our own teacher, then we bring the information to ourselves in a way which we can comprehend and internalize it.
