Darkness cannot say: “I precede the coming light”, but there is a sense in which light can say, “Darkness preceded me”.
Doubtless there is an event, X, in the future, by reference to which we may say that we are at present in a category of Not-X, but until X occurs, the category of Not-X is without reality. Only X can give reality to Not-X; that is to say, Not-Being depends for its reality upon Being. In this way we may faintly see how the creation of Time may be said automatically to create a time when Time was not, and how the Being of God can be said to create a Not-Being that is not God.
Everything written symbols can say has already passed by. They are like tracks left by animals. That is why the masters of meditation refuse to accept that writings are final. The aim is to reach true being by means of those tracks, those letters, those signs - but reality itself is not a sign, and it leaves no tracks. It doesn’t come to us by way of letters or words. We can go toward it, by following those words and letters back to what they came from. But so long as we are preoccupied with symbols, theories and opinions, we will fail to reach the principle.
"But when we give up symbols and opinions, aren’t we left in the utter nothingness of being?"
Translation is always a treason, and as a Ming author observes, can at its best be only the reverse side of a brocade—all the threads are there, but not the subtlety of color or design. But, after all, what great doctrine is there which is easy to expound? The ancient sages never put their teachings in systematic form. They spoke in paradoxes, for they were afraid of uttering half-truths. They began by talking like fools and ended by making their hearers wise. Lau Tzu himself, with his quaint humor, says, "If people of inferior intelligence hear of the Tao, they laugh immensely. It would not be the Tao unless they laughed at it."
