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. This set of study cards decodes some of the fundamental messages from the 22 GanZhi symbols. The Chinese character and key characteristics of each Stem or Branch are shown, providing invaluable insights into their symbolic and numerological meanings. For calligraphers and those who want to draw the characters correctly, the stroke order is clearly illustrated on separate cards. This accessible learning tool, for practitioners at any level, will help deepen understanding of many of the Chinese classical texts, classical Chinese medicine, Fengshui, Chinese astrology, traditional Chinese cosmology, Qigong, Neigong, Taiji, and other inner cultivation practices.
