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.
And the more you become aware of the unknown self - if you become aware of it - the more you realize that it is inseparably connected with everything else that is.
We have somehow conned ourselves into the notion that this moment is ordinary. This now moment, in which I'm talking and you're listening, is eternity.
Different Chinese philosophers, writing probably in 5-4 centuries B.C., presented some major ideas and a way of life that are nowadays known under the name of Taoism, the way of correspondence between man and the tendency or the course of natural world.
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.
Some believe all that parents, tutors, and kindred believe. They take their principles by inheritance, and defend them as they would their estates, because they are born heirs to them.
Really, the fundamental, ultimate mystery -- the only thing you need to know to understand the deepest metaphysical secrets -- is this: that for every outside there is an inside and for every inside there is an outside, and although they are different, they go together.
If you awaken from this illusion, and you understand that black implies white, self implies other, life implies death - or shall I say, death implies life - you can conceive yourself. Not conceive, but feel yourself, not as a stranger in the world, not as someone here on sufferance, on probation, not as something that has arrived here by fluke, but you can begin to feel your own existence as absolutely fundamental. What you are basically, deep, deep down, far, far in, is simply the fabric and structure of existence itself.
You know that if you get in the water and have nothing to hold on to, but try to behave as you would on dry land, you will drown. But if, on the other hand, you trust yourself to the water and let go, you will float. And this is exactly the situation of faith.
To go out of your mind once a day is tremendously important, because by going out of your mind you come to your senses. And if you stay in your mind all of the time, you are over rational, in other words you are like a very rigid bridge which because it has no give; no craziness in it, is going to be blown down by the first hurricane.
Although profoundly "inconsequential," the Zen experience has consequences in the sense that it may be applied in any direction, to any conceivable human activity, and that wherever it is so applied it lends an unmistakable quality to the work.
