While you are continuing this practice, week after week, year after year, your experience will become deeper and deeper, and your experience will cover everything you do in your everyday life. The most important thing is to forget all gain
ing ideas, all dualistic ideas. In other words, just practice zazen in a certain posture. Do not think about anything. Just remain on your cushion without expecting anything. Then eventually you will resume your own true nature. That is to say, your own true nature resumes itself.

Concentration is not to try hard to watch something... Concentration means freedom... In zazen practice we say your mind should be concentrated on your breathing, but the way to keep your mind on your breathing is to forget all about yourself and just to sit and feel your breathing.

and you will become friendly with others. This is the merit of Zen practice. But the way of practice is just to be concentrated on your breathing with the right posture and with great, pure effort. This is how we practice Zen.

Try always to keep the right posture, not only when you practice zazen, but in all your activities.

To be aware of the meaning of your life, you practice zazen.

The most important thing in taking the zazen posture is to keep your spine straight. Your ears and your shoulders should be on one line. Relax your shoulders, and push up towards the ceiling with the back of your head. And you should pull your chin in. When your chin is tilted up, you have no strength in your posture; you are probably dreaming. Also to gain strength in your posture, press your diaphragm down towards your hara, or lower abdomen. This will help you maintain your physical and mental balance. When you try to keep this posture, at first you may find some difficulty breathing naturally, but when you get accustomed to it you will be able to breathe naturally and deeply.

Usually when you practice zazen, you become very idealistic, and you set up an ideal or goal which you strive to attain and fulfill. But as I have often said, this is absurd. When you are idealistic, you have some gaining idea within yourself; by the time you attain your ideal or goal, your gaining idea will create another ideal.

Each moment of zazen is equally wholeness of practice, equally wholeness of realization. This is not only practice while sitting, it is like a hammer striking emptiness: before and after, its exquisite peal permeates everywhere. How can it be limited to this moment?

A mind full of preconceived ideas, subjective intentions, or habits is not open to things as they are. That is why we practice zazen: to clear our mind of what is related to something else.

Suzuki said that if we practiced zazen sincerely, we could gradually become free from enslavement to compulsive intellectual and emotional activity. He said calming the intellect would happen first, but that calming emotions was not so easy and would take longer.

Zazen is not learning to do concentration. It is the dharma gate of great ease and joy. It is undivided practice-realization.

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.

If we practice hard, concentrate on zazen, and organize our life so that we can sit well, we will find out what we are doing. But you have to be careful in the rules and way you establish. If it is too strict you will fail, if it is too loose, the rules will not work. Our way should be strict enough to have authority, an authority everyone should obey. Thu rules should be possible to observe.
This is how Zen tradition was built up, decided little by little, created by us in our practice. We cannot force anything. But once the rules have been decided, we should obey them completely until they are changed. It is not a matter of good or bad, convenient or inconvenient. You just do it without question. That way your mind is free.

Zen practice is to open up our small mind.
