There is no water like rainwater; no strength like one's own; no light like that of the eyes; and no wealth more dear than food grain.

If you mean to profit, learn to please.

It is not enough to prove something, one also has to seduce or elevate people to it. That is why the man of knowledge should learn how to speak his wisdom: and often in such a way that it sounds like folly!

The small wisdom is like water in a glass: clear, transparent, pure. The great wisdom is like the water in the sea: dark, mysterious, impenetrable.

It's good to learn from your mistakes. It's better to learn from other people's mistakes.

He who has access to the fountain does not go to the water-pot.
