The four chinese classics: tao te ching, analects, chuang tzu, mencius

Perhaps the most broadly influential spiritual text in human history, Lao Tzu's Tao Te Ching is the source of Taoist philosophy, which eventually developed into Ch'an (Zen) Buddhism. Equally influential in the social sphere, Confucious' Analects is the source of social wisdom in China. The Chuang Tzu is the wild and wacky prose complement to the Tao Te Ching. And with its philosophical story-telling, the Menicius adds depth and complexity to Confucius' vision.
