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.

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.

To get rid of villains and knaves, it is necessary to give them a way out. If you don't give them any leeway at all, they will be like trapped rats. If every way out is closed to them, they will chew up everything good.

There is much meaning in the word endure. For example, when dealing with unstable human feelings and uneven pathways in life, without endurance to hold you up, you may fall into a pit in the brush.

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.

Observe people with cool eyes, listen to their words with cool ears. Confront feelings with cool emotions, reflect on principles with a cool mind.

Our body is a small universe; to regulate emotions and feelings is a way of harmonization.
