Within the Taoist concept, the body has 3 basic layers: Physical Body, Soul/Subtle Body, and the Spirit Body. Each “body” has it’s own energy system, with a different “type” of Qi. For example, one may have an extremely strong physical body, however, due to some psychological trauma the Subtle Body is extremely weak and the person has very low will to survive. Martial Qi Gong, for the most part, focuses on the physical body. Yuan Shen Men practice focuses primarily on the Subtle Body, the bridge for the Physical to the Spirit. Of course, there usually may be some mental and physical health benefits as an added bonus to any cultivation system. However, if your primary goal is to improve your fighting ability, it would be time much better to train strength, conditioning, and learn some Chinese San Da “Free Fighting.”
