To speak of the luminous body is to speak of a living intelligence that glows from within the ordinary. It is not an abstract ideal, not a fantasy of perfect health, not a polished image of vitality. It is the felt presence of being inhabited by life. It is the subtle radiance that appears when breath meets attention, when movement meets permission, when sensation is welcomed instead of overridden. The luminous body is what remains when we stop treating ourselves as machines and begin recognizing ourselves as ecosystems.
