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?

The realms of good fortune and calamity in human life are all made of thoughts and imaginings. Therefore Buddhists say that the burning of desire for gain is itself a pit of fire, while drowning in greedy love is itself a bitter sea. The moment thoughts are pure, fierce flames become a pond; the moment you become aware, the boat has arrived on the further shore. If your thoughts vary at all, your world will immediately differ, so can we not be careful?

Unexpected hardship refines people; if you can accept it, both mind and body will benefit. If you cannot accept it, on the other hand, both mind and body will be harmed.

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 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.

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's shortcomings should be treated with tact; if you expose them crudely, this is attacking weakness with a weakness. When people are stubborn, it requires skill to influence them; if you treat them with anger and spite, this is treating stubbornness with stubbornness.
