If I understand Change, I shall make no great mistake in Life

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

You do not understand even life. How can you understand death?

Isn't it a pleasure to study and practice what you have learned? Isn't it also great when friends visit from distant places? If one remains not annoyed when he is not understood by people around him, isn't he a sage?

There may be men who act without understanding why. I do not. To listen much, pick out the good and follow it; to see much and ponder it: this comes next to understanding.

Therefore the superior man is watchful over himself, when he is alone.

Don't do unto others what you don't want others to do unto you.
