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.
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.
