"It is essential to understand this point thoroughly: that the thing-in-itself, whether animal, vegetable, or mineral, is not only unknowable-it does not exist. This is important not only for sanity and peace of mind, but also for the most "practical" reasons of economics, politics, and technology.. This is not to say only that things exist in relation to one another, but that what we call "things" are no more than glimpses of a unified process. Certainly, this process has distinct features which catch our attention, but we must remember that distinction is not separation."

Here's an example: someone says, "Master, please hand me the knife," and he hands them the knife, blade first. "Please give me the other end," he says. And the master replies, "What would you do with the other end?" This is answering an everyday matter in terms of the metaphysical. When the question is, "Master, what is the fundamental principle of Buddhism?" Then he replies, "There is enough breeze in this fan to keep me cool." That is answering the metaphysical in terms of the everyday, and that is, more or less, the principle zen works on. The mundane and the sacred are one and the same.

And although our bodies are bounded with skin, and we can differentiate between outside and inside, they cannot exist except in a certain kind of natural environment.

Tomorrow and plans for tomorrow can have no significance at all unless you are in full contact with the reality of the present, since it is in the present and only in the present that you live. There is no other reality than present reality, so that, even if one were to live for endless ages, to live for the future would be to miss the point everlastingly.

The whole point of Zen is to suspend the rules we have superimposed on things and to see the world as it is

We seldom realize, for example that our most private thoughts and emotions are not actually our own. For we think in terms of languages and images which we did not invent, but which were given to us by our society.

Buddha's doctrine: Man suffers because of his craving to possess and keep forever things which are essentially impermanent...this frustration of the desire to possess is the immediate cause of suffering.
