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

Since mountains, rivers, and the whole earth are but dust, what do you expect from the tiniest dust within dust? Since the flesh, the blood, and the entire human body are but a shadow, what do you look for in a shadow cast by another shadow? Thus, without wisdom one cannot have an enlightened mind.
