Yijing (I-Ching) theory is the foundation of Daoism and Chinese medicine, and this book explores the deep roots that they both share. Daoism and Chinese medicine both view the human body as a microcosm of the universe around us; what is happening outside affects us inside. Medical qigong is based on the premise that we can energetically affect something outside based on our intention inside. Much of medical qigong, one of the main branches of Chinese medicine, originates from the practices of Daoist shamanic healers. This book introduces a Chinese medicine healing system based on the principles of the Yijing that serve as the foundation of medical qigong and Daoist spiritual practices. The Yijing Medical Qigong System is a compilation of self-healing exercises and qi emission therapeutic treatment techniques based on Daoist medical qigong and Yijing theories. This system's approach is unique in that it focuses on the meanings of the trigrams rather than the hexagrams of the Yijing. The eight trigrams are used in innovative ways for healing the body, mind, and spirit. The Yijing Medical Qigong System is based on the premise that the Yijing theory that infuses Chinese medicine and Daoism is just as relevant today for healing and spiritual guidance it was three thousand years ago.
