After one has been in a lowly position, one knows how dangerous it is to climb to a high place, Once one has been in the dark, one knows how revealing it is to go into the light. Having maintained quietude, one knows how tiring compulsive activity is. Having nurtured silence, one knows how disturbing much talk is.

A grub in filth is dirty, but it changes into a cicada and sips dew in the autumn breeze. Rotting plants have no luster, but they turn into foxfire and glow in the summer moonlight. So we know that purity emerges from impurity, and light is born from darkness.

People are considered pure of heart when they do not approach power and pomp; but those who can be near without being affected are the purest of all. People are considered high-minded when they do not know how to plot and contrive; but those who know how yet do not do so are the highest of all.

Do not think about whatever service you may have done for others; think about what you may have done to offend them. Don't forget what others have done for you; forget what others have done to offend you.

...people of old deemed freedom from greed precious, and this is how they got beyond the world.

Human affairs are like a chess game. Only those who do not take it seriously can be called good players.

A net set up to catch fish may snare a duck; a mantis hunting an insect may itself be set upon by a sparrow. Machinations are hidden within machinations; changes arise beyond changes. So how can wit and cleverness be relied upon?
