The first text to restore the Four Canons of the Yellow Emperor to its rightful place alongside the Tao Te Ching - Presents the practical guidance of the Four Canons on the art of ruling, metaphysics, military matters, and ways of meditation - Includes translations of the earliest known versions of the Tao Te Ching - Highlights the many links between the Four Canons and the Tao Te Ching In 1973, in Mawangdui, China, a large number of silk manuscripts were discovered at an early Han burial place. Among these were two versions of the Tao Te Ching by Lao-tzu. Dated to around 200 bce, these manuscripts were much older than all existing versions and included, quite surprisingly yet deliberately, the Four Canons of the Yellow Emperor--a long-lost treatise never-before seen in modern times. 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.
