Books are as useful to a stupid person as a mirror is useful to a blind person.

A low-minded person should not be given good advice.

The ruler should employ person in tasks according to their abilities because Knowers ( or the means ) and efficient employees make impossible tasks also possible.

An enemy should be struck at his weak point.

He shall despise none, but hear the opinions of all. A wise man shall make use of even a child's sensible utterance.

He who shall practice these twenty virtues shall become invincible in all his undertakings.

Do not be very upright in your dealings for you would see by going to the forest that straight trees are cut down while crooked ones are left standing.
