People say that practicing Zen is difficult, but there is a misunderstanding as to why. It is not difficult because it is hard to sit in the cross- legged position, or to attain enlightenment. It is difficult because it is hard to keep our mind pure and our practice pure in its fundamental sense.
Shunryu SuzukiTo accept some idea of truth without experiencing it is like a painting of a cake on paper which you cannot eat.
Shunryu SuzukiAs long as you seek for something, you will get the shadow of reality and not reality itself.
Shunryu SuzukiWhen 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.
