The foundation of health lies not in supplementation, but in bodily warmth. When warmth is present, blood flows and meridians open; when warmth is lost, stagnation, dampness, and phlegm arise. True beneficial warmth is not fiery heat, but gentle vitality rooted in Yang Qi. Yang is not raised through forceful exercise, but through nourishing movement—slow, integrated, and non-depleting—exemplified by Taichi practice.
