Lieh-Tzü was major Taoist sage who lived c. 350 BCE. His writings use stories and fables to elucidate the Taoist philosophy of cooperating with nature; they illustrate the magical powers of the ancient sages who were so 'in the Tao' that they were able to prolong life, walk through solid rock, and levitate.
