Lao Zi:
The Tao te Ching (literally, "the classic of the way of virtue") is attributed to Lao Zi, though scholars disagree about his actual existence. In its very poetic form it teaches that there is a dynamic, cosmic structure underlying everything that happens in the world. We humans need to discover that Way (Tao), which is immanent in all aspects of the world, not a rule imposed from without; and we need to fit into it, letting things take their course, not exerting ourselves in opposition to it by trying to bend things to our will.
Our naming (describing) of things always falls short of the way things are, since things are not limited as our language presupposes. Even the Tao which we are trying to talk about here eludes our words. The original polarity is that of being and non-being, and it will be found to interplay throughout the world, with non-being (emptiness, what is not) having as much significance as does being (the fullness of things, what is). Thus the notion of the Tao recaptures the earlier Chinese concept of Yin and Yang, the polarities running through all things.

Fill your bowl to the brimand it will spill.
Keep sharpening your knife
and it will blunt.
Chase after money and security
and your heart will never unclench.
Care about people's approval
and you will be their prisoner.
Do your work, then step back.
The only path to serenity.
