For unless one is able to live fully in the present, the future is a hoax. There is no point whatever in making plans for a future which you will never be able to enjoy. When your plans mature, you will still be living for some other future beyond. You will never, never be able to sit back with full contentment and say, "Now, I've arrived!" Your entire education has deprived you of this capacity because it was preparing you for the future, instead of showing you how to be alive now.
The most strongly enforced of all known taboos is the taboo against knowing who or what you really are behind the mask of your apparently separate, independent, and isolated ego.
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.
The Tao belongs neither to knowing nor not knowing. Knowing is false understanding; not knowing is blind ignorance. If you really understand the Tao beyond doubt, it's like the empty sky. Why drag in right and wrong?
If you belong to an in-group of good, or saved, or elite people, you can only know that you’re in because someone else is out. You cannot live on the right side of the tracks without there being a wrong side of the tracks, so you ought to be grateful to the outside for having the privilege of being on the inside.
To be silent is not to lose your tongue. On the contrary, it is only through silence that one can discover something new to talk about. One who talked incessantly, without stopping to look and listen, would repeat himself ad nauseam.
There is nothing wrong with meditating just to meditate, in the same way that you listen to music just for the music. If you go to concerts to "get culture" or to improve your mind, you will sit there as deaf as a doorpost.
Breathing is important in the practice of meditation because it is the faculty in us that is simultaneously voluntary and involuntary. You can feel that you are breathing, and equally you can feel that it is breathing you. So it is a sort of bridge between the voluntary world and the involuntary world — a place where they are one.
We think that the world is limited and explained by its past. We tend to think that what happened in the past determines what is going to happen next, and we do not see that it is exactly the other way around! What is always the source of the world is the present; the past doesn't explain a thing. The past trails behind the present like the wake of a ship and eventually disappears.
Western religions are more concerned with behavior, doctrine, and belief than with any transformation of the way in which we are aware of ourselves and our world.
