In matters of desire, don't get hastily involved because of easy availability; once you get involved, you will sink in deeply. In matters of principle, don't back off for fear of difficulty; once you back down, you will lose your ground entirely.

The substance of mind is the substance of heaven. A joyful thought is an auspicious star or a felicitous cloud. An angry thought is a thunderstorm or a violent rain. A kind thought is a gentle breeze or a sweet dew. A stern thought is a fierce sun or an autumn frost. Which of these can be eliminated? Just let them pass away as they arise, open and unresisting, and your mind merges with the spacious sky.

Those in public office who do not love the people are thieves stealing salaries. Those who teach but do not themselves practice what they teach are mere talkers. Those who try to do successful work without considering development of character will find it insubstantial.

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.

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.
