Those who know when to halt are unharmed.

The Tao is like a well; used but never used up.

He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.

Do not look only at yourself, and you will see much. Do not justify yourself, and you will be distinguished. Do not brag, and you will have merit. Do not be prideful, and your work will endure.

Those who have hardened, have a covenant with Death. Those who remain gentle are conjoined with Life.

If a person seems wicked, do not cast him away. Awaken him with your words, elevate him with your deeds, repay his injury with your kindness. Do not cast him away; cast away his wickedness.

Obscure, like muddy waters.
