Tao Te Ching on Protection

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.

They who preserve this method of the Tao do not wish to be full (of themselves). It is through their not being full of themselves that they can afford to seem worn and not appear new and complete.

The Tao is (like) the emptiness of a vessel; and in our employment of it we must be on our guard against all fulness. How deep and unfathomable it is, as if it were the Honoured Ancestor of all things!

Though in its primordial simplicity it may be small, the whole world dares not deal with (one embodying) it as a minister. If a feudal prince or the king could guard and hold it, all would spontaneously submit themselves to him.

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.

When the mother is found, we know what her children should be. When one knows that he is his mother's child, and proceeds to guard (the qualities of) the mother that belong to him, to the end of his life he will be free from all peril.

Therefore (to guard against this), the sage keeps the left-hand portion of the record of the engagement, and does not insist on the (speedy) fulfilment of it by the other party. (So), he who has the attributes (of the Tao) regards (only) the conditions of the engagement, while he who has not those attributes regards only the conditions favourable to himself.

A skilful (commander) strikes a decisive blow, and stops. He does not dare (by continuing his operations) to assert and complete his mastery. He will strike the blow, but will be on his guard against being vain or boastful or arrogant in consequence of it. He strikes it as a matter of necessity; he strikes it, but not from a wish for mastery.
