TCM has an about 3000-year-old history, and its theory is based on very ancient and systematic Chinese philosophy. It holds that everything in the universe is formed from Qi (subtle energy) and follows Dao (natural regulation or universal law).
According to this philosophy, the invisible energy of human internal organs connects to and communicates with the outside environment and the universe. TCM has continuously applied this theory, and says, “If you keep your mind in a quiet, calm and void state, and guide your real Qi with deep consciousness, how could you get an illness?” . Yangshengshu’s fundamental principle and technique utilizes mind–body training meditation or exercise to prevent illness, and attain health and longevity. Yangshengshu is a guide to a tranquil, balanced lifestyle and spiritual sublimation state — the healthy lifestyle.
TCM’s discovery and systematic theoretical development probably was not mainly accumulated through earlier practice experiences, but was based on the knowledge of extraordinary capabilities and special functions of sages in a special meditation state. As prominent doctor Li Shizhen (1518–1593) said, “The meridian channels in the body would be observed only by visualization of the inside of the body during special meditation.” How else, in ancient times, without advanced scientific technology and equipment, could they accurately picture complicated meridian charts? Yangshengshu or Qigong meditation (“Qi” — bio-energy; “gong” — practice and accumulation of Qi) is the traditional Chinese philosophy and methodology for material, energy, and information exchange between the universe and humanity, which teaches how to achieve health, longevity, and intelligence.
All well-recognized Chinese medical experts from different generations appreciated the wonder of Yangshengshu and used it as the fundamental theory of their medical practice. In this way Chinese medicine maintained and improved ancient knowledge. Many practitioners may not realize the relationship between Yangshengshu and TCM, though they follow general principles suggested by The Inner Canon of the Yellow Emperor for Chinese medical practice. Ordinary practitioners have no means to significantly develop TCM. It should be noted that training for TCM significantly differs from that of Conventional Western Medicine (CWM). The continually updated medical information taught to Western doctors does not die with the individual doctor. However, Chinese medical doctors, educated in traditional university systems, must also be trained with masters, and practice Yangshengshu meditation to cultivate their wisdom, to visualize and affect the intangible Qi system.
