Zen is not a particular state but the normal state: silent, peaceful, unagitated. In Zazen neither intention, analysis, specific effort nor imagination take place. It's enough just to be without hypocrisy, dogmatism, arrogance — embracing all opposites.

Zen is the purest of meditations: just sit silently, doing nothing.

Zen is a form of liberation - being liberated from Yin and Yang elements, and enabling you to remain calm and cool when you are troubled. Zen is not something definite and tangible, it is a refuge for mental solace. Zen is about concentration of mind. It is a profound culture, enabling people to gain spiritual tranqulity and be awakened. Even though not a word is spoken, it enables one to gain a thorough understanding of the truth of life. This is what we call the harmony between Yin and Yang. It is like a substance deep in your soul, generating a kind of wisdom and energy in your mind. It is also a kind of energy of self-confidence, helping you to achieve self-emancipation, self-regulation and self-perfection, leading you to the path of success. As such, Buddhism talks about ‘Faith, Commitment, and Action’. The theory, when applied in the human realm, is all about Zen. Concentration gives rise to wisdom. With concentration, the mind will be focused and it will not be drifting apart. Hence, the problem of schizophrenia will not arise. Zen culture is about the state of mind. It is a kind of positive energy! Positive energy is a kind of compassion, which enables people to understand each other when they encounter problems, to understand the country and society at large, and to understand their family and children, colleagues and friends. In this way, people will be able to live in peaceful co-existence and remain calm when they are faced with problems.When you see things in perspective using rationality and positive energy, you are able to change your viewpoint pertaining to a certain issue. This is the moment Zen arises in your mind! In fact, Zen is within you. This theory is very profound.

Zen is a liberation from time. For if we open our eyes and see clearly, it becomes obvious that there is no other time than this instant, and that the past and the future are abstractions without any concrete reality.

"Zen concentrates on the importance of seeing into one's own nature now at this moment - not in five minutes when you have had time to "accept" yourself, nor ten years ahead when you have had time to retire to the mountains and meditate."

Zen is nothing to get excited about.

So when you practice zazen, your mind should be concentrated on your breathing. This kind of activity is the fundamental activity of the universal being. Without this experience, this practice, it is impossible to attain absolute freedom.

Zazen practice and everyday activity are one thing. We call zazen everyday life, and everyday life zazen.

Zen is not some fancy, special art of living. Our teaching is just to live, always in reality, in its exact sense. To make our effort, moment after moment, is our way. In an exact sense, the only thing we actually can study in our life is that on which we are working in each moment. We cannot even study Buddha’s words.”

“So we should be concentrated with our full mind and body on what we do; and we should be faithful, subjectively and objectively, to ourselves, and especially to our feelings. Even when you do not feel so well, it is better to express how you feel without any particular attachment or intention. So you may say, “Oh, I am sorry, I do not feel well.

Zen practice is to open up our small mind.

We say concentration, but to concentrate your mind on something is not the true purpose of Zen. The true purpose is to see thing 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.

One has to reach to the absolute state of awareness: that is Zen. You cannot do it every morning for a few minutes or for half an hour and then forget all about it. It has to become like your heartbeat. You have to sit in it, you have to walk in it. Yes, you have even to sleep in it.

Most of us in our thinking are wandering from this to that to the other thing, and are constantly distracted. And Zen is the opposite of that. It’s being completely here, fully in the present. And you know when you’re completely concentrated, you’re not really aware of your own existence. It’s rather the same as the sense of sight. If you see your eyes, that is to say if you see spots in front of your eyes, or something on the lens of the eye, then you’re not seeing properly. To the degree to which you’re seeing properly, you’re unaware of your eyes. In the same way, if your clothes fit well, you’re unaware of them on your body. And if you’re completely concentrated on what you’re doing, you’re unaware of yourself.

So you could say in a very simple way that the real concern of Zen is to realize — not merely rationally but in one’s bones — that the world inside your skin and the world outside your skin are all one world and one being, one self. And you are it.
