Zazen practice and everyday activity are one thing. We call zazen everyday life, and everyday life zazen.

From True Emptiness The Wondrous Being Appears

We die, and we do not die.

To renounce things is not to give them up. It is to acknowledge that all things go away.

Those who sit perfectly physically usually take more time to obtain the true way of Zen.

If enlightenment comes first, before thinking, before practice, your thinking and your practice will not be self-centered. By enlightenment I mean believing in nothing, believing in something which has no form or no color, which is ready to take form or color. This enlightenment is the immutable truth. It is on this orginal truth that our activity, our thinking, and our practice should be based.

In reflecting on our problems, we should include ourselves.
