Chapter 27, Part 1B - Chuang Tzu

These repeated words which make up seven tenths of it are intended to put an end to argument. They can do this because they are the words of the elders. If, however, one is ahead of others in age but does not have a grasp of the warp and woof, the root and branch of things, that is commensurate with his years, then he is not really ahead of others. An old man who is not in some way ahead of others has not grasped the Way of man, and if he has not grasped the Way of man, he deserves to be looked on as a mere stale remnant of the past.

With these goblet words that come forth day after day, I harmonize all things in the Heavenly Equality, leave them to their endless changes, and so live out my years. As long as I do not say anything about them, they are a unity. But the unity and what I say about it have ceased to be a unity; what I say and the unity have ceased to be a unity.

Therefore I say, we must have no-words! With words that are no-words, you may speak all your life long and you will never have said anything. Or you may go through your whole life without speaking them, in which case you will never have stopped speaking.
