A clear sunny day can suddenly shift to thunder and lightning, a raging storm can suddenly give way to a bright moonlit night. The weather may be inconstant, but the sky remains the same. The substance of the human mind should also be like this.

Conceit and arrogance are acquired states of mind. Conquer acquired states of mind, and basic sanity can unfold. Passion and willfulness are part of false consciousness; erase false consciousness, and true consciousness will appear.

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.

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.

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.

Do not think about whatever service you may have done for others; think about what you may have done to offend them. Don't forget what others have done for you; forget what others have done to offend you.

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.
