The Master said, “The gentleman understands what is right, whereas the petty man understands profit.” (Analects 4.16)

What the wise seek is in themselves

A blemish may be removed from a diamond by careful polishing, but evil words once spoken cannot be effaced.

A gentleman wishes to be slow to speak and quick to act.

The superior man is quiet and calm, waiting for the appointments of heaven, while the mean man walks in dangerous paths, looking for lucky occurrences.

The demands that good people make are upon themselves; Those that bad people make are upon others.

Do not impose on others what you yourself do not desire.
