Garden of Serenity

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

A conventional man delights in his prosperity, but the superior man’s happiness comes from his adversity. A conventional man grieves at his dissatisfaction, but the superior man’s sorrow arises from his satisfaction. This is so because the sorrow and happiness of a conventional man are induced by passion and those of the superior man by intellect.
