Because you yourself have imperfections, you therefore feel the environment is imperfect. It is like a mirror with an uneven surface, the images reflected in it are also distorted. Or, it is like the surface of water disturbed by ripples, the moon reflected in it is irregular and unsettled. If the surface of the mirror is clear and smooth, or if the air on the surface of the water is still and the ripples calmed, then the reflection in the mirror and the moon in the water will be clear and exact. Therefore, from the point of view of Chan, the major cause of the pain and misfortune suffered by humanity is not the treacherous environment of the world in which we live, nor the dreadful society of humankind, but the fact that we have never been able to recognise our basic nature. So the method of Chan is not to direct us to evade reality, nor to shut our eyes like the African ostrich when enemies come, and bury our heads in the sand, thinking all problems are solved. Chan is not a self-hypnotising idealism.
