Wisdom

What is a good man?

Simply one whose life is useful to the world.

And a bad man is simply one whose life is harmful to others.

There are, however, those who are harmful and yet enjoy a good reputation.

And

Who manage to profit by a show of unselfishness,

These are the worst of all.

(From a conversation between Chang Chao and Hanchen. 15^th century)

there is a time for everything, and everything changes
