You should not be too much of a purist in your way of life, for you need to be able to accept all that is foul. You should not be too clear in making distinctions in social interactions, for you need to accept everyone whether they are good or bad, wise or foolish.

To conquer demons, first conquer your mind. When the mind is subdued, demons withdraw obediently. To control knaves, first control your own mood. When your mood is balanced, scoundrels cannot get at you.

Diligence means to be keen in matters of virtue and justice, but worldly people use diligence to solve their economic difficulties. Frugality means to have little desire for material goods, but worldly people use frugality as a cover for stinginess. Thus do watchwords of enlightened life turn into tools for the private business of small people. What a pity!

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.

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.

When water isn't rippled, it is naturally still. When a mirror isn't clouded, it is clear of itself. So the mind is not to be cleared; get rid of what muddles it, and its clarity will spontaneously appear. Pleasure need not be sought; get rid of what pains you, and pleasure is naturally there.

When you meet dishonest people, move them with sincerity. When you meet violent people, affect them with gentility. When you meet warped people, inspire them with justice. Then the whole world enters your forge.
