Based on both the Mawangdui version of the Tao Te Ching and the recently discovered Guodian version, this book is the first to restore the Four Canons of the Yellow Emperor to its rightful place alongside the Book of the Way. Complementing the philosophy of the Tao Te Ching with its more practical advice, the Four Canons cover the art of ruling, metaphysics, military matters and ways of meditation. Showing how this pairing of texts established the foundations of the Han Dynasty's power, Jean Levi offers extensive notes throughout the text, providing information essential for understanding as well as highlighting the many connections between these two classic works. “This edition, offering both a familiar and an unfamiliar text, should be of immense interest to scholars as well as devotees of the Way; essential for any scholarly collection on Asian religions.” - Library Journal
