When you are practicing zazen, do not try to stop your thinking. Let it stop by itself. If something comes into your mind, let it come in, and let it go out. It will not stay long. When you try to stop your thinking, it means you are bothered by it. Do not be bothered by anything. It appears as if something comes from outside your mind, but actually it is only the waves of your mind, and if you are not bothered by the waves, gradually they will become calmer and calmer.
Shunryu SuzukiThe purpose of studying Buddhism is not to study Buddhism, but to study ourselves. That is why we have teaching. But the teaching is not ourselves. It is some explanation of ourselves. To study the teaching is to know yourselves. That is why we do not ever attach to the teaching, or to the teacher. The moment you meet a teacher you should leave the teacher, and you should be independent. You want a teacher so that you can be independent. So you study yourselves. You have the teacher for yourselves, not for the teacher.
Shunryu SuzukiStrictly speaking, there is no such thing as an enlightened person. There is only enlightened activity.
