A fifth obstacle, common among people who spend much time at Zen centers, is substituting talk and discussion and reading for persistent practice itself. The less we say about practice, the better. Outside of a direct student-teacher setting, the last thing that I will talk about is Zen practice. And I don’t talk about the dharma. Why talk about it? My job is to notice how I violate it. You know the old saying, “He who knows does not say, and he who says does not know.”
