Words are the voice of the heart.

The superior man undergoes three changes. Looked at from a distance, he appears stern; when approached, he is mild; when he is heard to speak, his language is firm and decided.

Cultivate the root; the leaves and branches will take care of themselves.

Sincerity is the end and beginning of things; without sincerity there would be nothing.

Unify your attention. Do not listen with your ears, but with your mind. Do not listen with your mind but with your essence.

Without goodness a man cannot endure adversity for long, nor can he enjoy prosperity for long. The good man is naturally at ease with goodness. The wise man cultivates goodness for its advantage.

The firm, the enduring, the simple, and the modest are near to virtue.
