From Chapter 12 ("Taking It Home") of Subtle Sound: The Zen Teachings of Maurine Stuart:

... Everything changes. Nothing lasts forever—not even these things that we may think are so true. A dogmatic attitude about these matters, about one's beliefs and opinions, is against the true nature of things. It doesn't fit. Sitting on the cushion, we understand this. We come to understand these changes. We are experiencing the subtle changes in our attitude, in our body and its condition, in the way we taste our food in the way our feet feel the floor, in the way we hear everything. Everything changes. This moment is what we have: nothing else. That's it. So open up to it more and more. No intolerant and self-righteous attitudes, please. Just find out for yourselves, in a calm and reasonable way, what this wonderful practice is about. Let us accept and work with whatever our present condition has brought us. And in doing this, even a hard life can become a joyful one. Sitting on the cushion, we are tuning in to the first principle of the universe, sensing what an amazing and marvelous opportunity this life as a human being is.
