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.
Think about food on a full stomach and you find you don't care about taste. Think of lust after making love, and you find you don't care about sex. Therefore, if people always reflect on the regret they will feel afterward to forestall folly at the moment, they will be stable and will not err in action.
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.
Even if you can't get rid of the heat, as long as you can get rid of bother with the heat, your body is always on a cool terrace. Even if you can't get rid of poverty, as long as you can get rid of the sadness of poverty, your mind always lives in a comfortable abode.
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.
Soil with a lot of manure in it produces abundant crops; water that is too clear has no fish. Therefore, enlightened people should maintain the capacity to accept impurities and should not be solitary perfectionists.
