Since before time and space were, the Tao is. It is beyond is and is not.

Nothing in the world is more flexible and yielding than water. Yet when it attacks the firm and the strong, none can withstand it, because they have no way to change it. So the flexible overcome the adamant, the yielding overcome the forceful. Everyone knows this, but no one can do it.

Because every portion of the body, mind, and spirit yearns for the integration of yin and yang, angelic intercourse is led by the spirit rather than the sexual organs. . . . Where ordinary intercourse unites sex organs with sex organs, angelic cultivation unites spirit with spirit, mind with mind, and every cell of one body with every cell of the other body.

All things issue from it; all things return to it. To find the origin, trace back the manifestations. When you recognize the children and find the mother, you will be free of sorrow. If you close your mind in judgements and traffic with desires, your heart will be troubled. If you keep your mind from judging and aren't led by the senses, your heart will find peace. Seeing into darkness is clarity. Knowing how to yield is strength. Use your own light and return to the source of light. This is called practicing eternity.

The wise man doesn't compete; therefore nobody can compete with him.

Therefore, if a great kingdom humbles itself before a small kingdom, it shall make that small kingdom its prize. And if a small kingdom humbles itself before a great kingdom, it shall win over that great kingdom. Thus the one humbles itself in order to attain, the other attains because it is humble. If the great kingdom has no further desire than to bring men together and to nourish them, the small kingdom will have no further desire than to enter the service of the other. But in order that both may have their desire, the great one must learn humility.

A good athlete can enter a state of body-awareness in which the right stroke or the right movement happens by itself, effortlessly, without any interference of the conscious will. This is a paradigm for non-action: the purest and most effective form of action. The game plays the game; the poem writes the poem; we can't tell the dancer from the dance. It happens when we trust the intelligence of the universe in the same way that an athlete or a dancer trusts the superior intelligence of the body.
