'Not to be cheered by praise, Not to be grieved by blame, But to know thoroughly one's own virtues or powers Are the characteristics of an excellent man.'

Stanza 58 'A foolish man proclaimeth his qualifications; A wise man keepeth them secret within himself; A straw floateth on the surface of the water, But a precious gem placed upon it sinketh.'

Stanza 59 'It is only narrow-minded men that make such distinctions As "This is our friend, this our enemy"; A liberal-minded man showeth affection for all. For it is uncertain who may yet be of aid to one.'

Stanza 118 'Much talking is a source of danger; Silence is the means of avoiding misfortune: The talkative parrot is shut up in a cage; Other birds, which cannot talk, fly about freely.'

Stanza 134 'The greatest wealth consisteth in being charitable, And the greatest happiness in having tranquility of mind. Experience is the most beautiful adornment; And the best comrade is one that hath no desires.'

Stanza 173 'Men of little ability, too, By depending upon the great, may prosper; A drop of water is a little thing, But when will it dry away if united to a lake?'
