True knowledge is when one knows the limitations of one's knowledge.

Let mourning stop when one's grief is fully expressed.

If one learns from others, but does not think, one will be bewildered. If, on the other hand, one thinks but does not learn from others, one will be in peril.

Signs and symbols rule the world, not words nor laws.

If a man withdraws his mind from the love of beauty, and applies it as sincerely to the love of the virtuous; if, in serving his parents, he can exert his utmost strength; if, in serving his prince, he can devote his life; if in his intercourse with his friends, his words are sincere - although men say that he has not learned, I will certainly say that he has.

If I do not participate in the sacrifice, it is as if I did not sacrifice at all.

Wherever you go, go with all your heart.
