When the liver is diseased, the eyesight fails; when the kidneys are diseased, the hearing is adversely affected. The disease is not visible, but its effects are. Therefore, enlightened people, wishing to be free from obvious faults, first get rid of hidden faults.

Those who live simply are often pure, while those who live luxuriously may be slavish and servile. It seems that the will is clarified by plainness, while conduct is ruined by indulgence.

When the rich and well-established, who should be generous, are instead spiteful and cruel, they make their behavior wretched and base in spite of their wealth and position. When the intellectually brilliant, who should be reserved, instead show off, they are ignorant and foolish in their weakness in spite of their brilliance.

The sickness of indulging desires can be treated, but the sickness of clinging to abstract principles is hard to treat. Obstacles presented by events and objects can be removed, but obstacles presented by social principles are hard to remove.

Don't be too severe in criticizing people's faults; consider how much they can bear. Don't be too lofty in enjoining virtue, so people may be able to follow.

If you are not lax when at leisure, you will be effective when busy. If you are not absentminded in tranquility, that will be useful in action. If you are not hypocritical in private, that will show up in public.

The powerful and prominent soar like dragons, the heroic and valiant fight like tigers: but if you look upon them with cool eyes, they are like ants gathering on rancid meet, like flies swarming on blood. Judgments of right and wrong bristle like porcupine quills: but if you meet them with cool feelings, that is like a forge melting metal, like hot water dissolving snow.
