Zen Mind, Beginner's Mind

Useful advice about the right way to think about zazen practice. I've found books that that were very much about the practical aspects of zazen (how to sit, how to breathe, etc.) and others that were about the philosophical nature of zen, but this is the first one I've found that was about how one should think about one's practice. And it seems very important, because there seem to be many ways to think about your practice that can actually defeat the purpose of it. Side note: The audio quality of this CD set was surprisingly bad, like it was recorded on a cheap tape recorder. Maybe it was? Anyway, that doesn't matter much, because the advice was clear and useful.
