When you listen for it, there is nothing to hear. When you use it, it is inexhaustible.

The best athlete wants his opponent at his best. The best general enters the mind of his enemy. The best businessman serves the communal good. The best leader follows the will of the people. All of the embody the virtue of non-competition. Not that they don't love to compete, but they do it in the spirit of play. In this they are like children and in harmony with the Tao.
Softness triumphs over hardness, feebleness over strength. What is more malleable is always superior over that which is immoveable. This is the principle of controlling things by going along with them, of mastery through adaptation.
Seal the openings, shut the doors, and until your last day you will not be exhausted. Widen the openings, interfere, and until your last day you will not be safe.
