From A Chinese Garden of Serenity (1959), by Hung Tzu-ch’eng, translated by Chao Tze-chiang:

The attitude of people towards me may be warm or cold, but I respond neither gladly nor resentfully; the tastes of the world may be savory or insipid, but I react neither happily nor disgustedly. If one does not fall into the trap of the mundane, one knows the ways of living in, and escaping from, the world.
