Shunryu Suzuki

The only effort that will help you is to count your breathing, or to concentrate on your inhaling and exhaling. “We say concentration, but to concentrate your mind on something is not the true purpose of Zen. The true purpose is to see things as they are, to observe things as they are, and to let everything go as it goes. This is to put everything under control in its widest sense. Zen practice is to open up our small mind. So concentrating is just an aid to help you realize “big mind,” or the mind that is everything. If you want to discover the true meaning of Zen in your everyday life, you have to understand the meaning of keeping your mind on your breathing and your body in the right posture in zazen. You should follow the rules of practice and your study should become more subtle and careful. Only in this way can you experience the vital freedom of Zen.”(Zen Mind, Beginner’s Mind)
