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 SuzukiThe mind of the beginner is empty, free of the habits of the experts, ready to accept, to doubt, and open to all possibilities.
Shunryu SuzukiFaith is a state of openness or trust...In other words, a person who is fanatic in matters of religion, and clings to certain ideas about the nature of God and the universe, becomes a person who has no faith at all. Instead they are holding tight. But the attitude of faith is to let go, and become open to the truth, whatever it might turn out to be.
