The Yellow Emperor's Inner Classic, the Neijing, has been a source book for traditional Chinese medicine for two thousand years. The Way of Heaven is a translation of the first two chapters together with a commentary. In Suwen chapter 1 the Yellow Emperor, Huangdi, asks why we no longer retain our vitality into old age. The answer given by his minister, Qi Bo, indicates that mankind no longer lives in harmony with heaven & earth. Following this declaration the seven & eight year natural cycles for women & men are described & discussed. Chapter 2 continues with an explanation of how we should live in tune with the four seasons, & explains behaviour appropriate to the time of the year. It introduces the concept of the five elements as resonances of the energies of the four seasons. Wide-ranging in their aim & scope, these chapters present a particular philosophy of health, emphasising the need to live in harmony with heaven & earth, in tune with natural cycles & stages of life. Following the way of heaven is the key to health & vitality, & losing the way the root of all pathology, both on an individual & planetary level. This book is translated from the French by Peter Firebrace.
