And then there's Gary Snyder:
"It is a perfectly simple, ordinary activity to be silent, to pay attention to your own consciousness and your breath, and to temporarily stop listening or looking at things that are coming in from the outside. To let them pass through you as they happen. There's no question that spending time with your own consciousness is instructive. You learn a lot. You can just watch what goes on in your own mind, and some of the beneficial effects are you get bored with some of your own tapes and quit playing them back to yourself."
