Essential reading for serious students of Chinese practical arts, including medicine, martial arts and FengShui, Master Zhongxian Wu and Dr Karin Taylor Wu provide a detailed explanation of the 22 GanZhi symbols in this book, outlining the characteristics of each, and their interactions and relationships. TianGan (Heavenly Stems) and DiZhi (Earthly Branches), commonly abbreviated to GanZhi, originated in the ancient Chinese cosmological sciences and is a complex calendrical system which was created to codify the patterns of life and of the universe itself. The ten symbols of Gan express the Yin or Yang perspective of Five Elements and embody the Way of Heaven. The 12 symbols of Zhi, made manifest in the 12 animals of the Chinese zodiac, hold the root of each Element and embrace the Way of Earth. Poetic summaries from the Song dynasty give the reader a deep understanding of the nature of each Stem and their relationship to each other.Offering an unprecedented insight into the subtleties and far-reaching influence of this ancient system, this book will be invaluable for the study or practice of Chinese medicine, FengShui, Chinese astrology, traditional Chinese cosmology, Qigong, Taiji, and other inner cultivation practices.
