The body of light, sometimes called the 'astral body' or the 'subtle body,' is a "quasi material" aspect of the human body, being neither solely physical nor solely spiritual, posited by a number of philosophers, and elaborated on according to various esoteric, occult, and mystical teachings. Other terms used for this body include body of glory, spirit-body, radiant body, luciform body, augoeides ('radiant'), astroeides ('starry or sidereal body'), and celestial body.
