Qigong and TCM (Traditional Chinese Medicine) are interwoven. TCM theory gives a more detailed practical view of what can go wrong (and, somewhat less so, what can go right), what not to do, and how to intelligently assess a situation and come up with a sensible remedy. To instruct qi gong to others, who will present a wide range of energetic patterns, its just responsible to have some knowledge of TCM. imho.
Lonny Jarrett is not from the TCM tradition, invented 50 years ago by Maoists, but from the Worsley Five Elements School of oriental medicine. Worsley is an Englishman.
Worsley took an aspect of Classical Chinese Medicine (CCM) and amplified the importance of the five phases, including the shen aspect – which had been effectively removed from TCM. Shen was too vague, too unscientific, too spiritual for the New Scientific Man the Maoists were re-inventing.
