Aura is a traditional term for the protective psychic and spiritual energy fields that surround and penetrate the physical body. Historically, artists depict halos around the heads of individuals to denote their spirituality. Biblically, writers refer to the raiment or countenance of light in an attempt to describe the field of spiritual energy around angels, men, and women. It is from this invisible atmosphere that we receive our first impression of people. From this intuitive nature, we form impressions and experience emotions and feelings regarding them and ourselves. Quantum physics describes the universe as energy. Psychology, Eastern therapy, and complementary medicine have terms for life as energy.
