So the most difficult thing is always to keep your beginner's mind. There is no need to have a deep understanding of Zen. Even though you read much Zen literature, you must read each sentence with a fresh mind. You should not say, "I know what Zen is," or "I have attained enlightenment." This is also the real secret of the arts: always be a beginner. Be very very careful about this point. If you start to practice zazen, you will begin to appreciate your beginner's mind. It is the secret of Zen practice.
Shunryu SuzukiThose who sit perfectly physically usually take more time to obtain the true way of Zen.
Shunryu SuzukiI discovered that it is necessary, absolutely necessary, to believe in nothing. That is, we have to believe in something which has no form and no color--something which exists before all forms and colors appear... No matter what god or doctrine you believe in, if you become attached to it, your belief will be based more or less on a self-centered idea.
