5 Heaven and earth do not act from (the impulse of) any wish to be benevolent; they deal with all things as the dogs of grass are dealt with. The sages do not act from (any wish to be) benevolent; they deal with the people as the dogs of grass are dealt with. May not the space between heaven and earth be compared to a bellows? 'Tis emptied, yet it loses not its power; 'Tis moved again, and sends forth air the more. Much speech to swift exhaustion lead we see; Your inner being guard, and keep it free. 6 The valley spirit dies not, aye the same; The female mystery thus do we name. Its gate, from which at first they issued forth, Is called the root from which grew heaven and earth. Long and unbroken does its power remain, Used gently, and without the touch of pain. 7 Heaven is long-enduring and earth continues long. The reason why heaven and earth are able to endure and continue thus long is because they do not live of, or for, themselves. This is how they are able to continue and endure. Therefore the sage puts his own person last, and yet it is found in the foremost place; he treats his person as if it were foreign to him, and yet that person is preserved. Is it not because he has no personal and private ends, that therefore such ends are realised? 8 The highest excellence is like (that of) water. The excellence of water appears in its benefiting all things, and in its occupying, without striving (to the contrary), the low place which all men dislike. Hence (its way) is near to (that of) the Tao. The excellence of a residence is in (the suitability of) the place; that of the mind is in abysmal stillness; that of associations is in their being with the virtuous; that of government is in its securing good order; that of (the conduct of) affairs is in its ability; and that of (the initiation of) any movement is in its timeliness. And when (one with the highest excellence) does not wrangle (about his low position), no one finds fault with him. 9 It is better to leave a vessel unfilled, than to attempt to carry it when it is full. If you keep feeling a point that has been sharpened, the point cannot long preserve its sharpness. When gold and jade fill the hall, their possessor cannot keep them safe. When wealth and honours lead to arrogancy, this brings its evil on itself. When the work is done, and one's name is becoming distinguished, to withdraw into obscurity is the way of Heaven. 10 When the intelligent and animal souls are held together in one embrace, they can be kept from separating. When one gives undivided attention to the (vital) breath, and brings it to the utmost degree of pliancy, he can become as a (tender) babe. When he has cleansed away the most mysterious sights (of his imagination), he can become without a flaw. In loving the people and ruling the state, cannot he proceed without any (purpose of) action? In the opening and shutting of his gates of heaven, cannot he do so as a female bird? While his intelligence reaches in every direction, cannot he (appear to) be without knowledge? (The Tao) produces (all things) and nourishes them; it produces them and does not claim them as its own; it does all, and yet does not boast of it; it presides over all, and yet does not control them.
