An aura, according to New Age metaphysics, is a colored outline , or set of contiguous outlines, allegedly emanating from the surface of an object. Auras are not to be confused with the aureoles or halos of saints, which are devices of Christian iconography used to depict the radiance of light associated with divine infusion. In the New Age, even the lowly amoeba has an aura, as does the mosquito and every lump of goat dung. The aura supposedly reflects a supernatural energy field or life force that permeates all things. Human auras allegedly emerge from the Human Energy Field.
