Every person has an aura. The aura is an energy field surrounding the body and which serves three purposes. First, it provides life force for your the physical body. Without the aura, the body dies. Second, the aura filters inbound energy. The bad stuff is kept out and clean energy is drawn in for processing by the chakras. Finally the aura bridges the body and soul together. Auric energy is not spiritual, neither is it purely physical. It lies in between and keeps the diametrical aspects of the human being in homeostasis.
