Taoist Teachings Translated from the Book of Lieh-Tzü...
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.
