Learning without thought is labor lost; thought without learning is perilous.

When one cultivates to the utmost the principles of his nature, and exercises them on the principle of reciprocity, he is not far from the path.

Reviewing the day's lessons. Isn't it joyful? Friends come from far. Isn't it delightful? One has never been angry at other's misunderstanding. Isn't he a respectable man?

Time flows away like the water in the river.

Ask yourself constantly, "What is the right thing to do?" Behave toward everyone as if receiving a great guest.

A superior man in dealing with the world is not for anything or against anything. He follows righteousness as the standard.

The superior man does not mind being in office; all he minds about is whether he has qualities that entitle him to office. He does not mind failing to get recognition; he is too busy doing the things that entitle him to recognition.
