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. We use common-sense terms such as blue mood , red with anger, green with envy, full of energy, or radiant beauty. Such terms are similar to how individuals with spiritual sight describe the aura. 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. Yoga psychology views the aura as an energy field surrounding the body, interacting through spiritual and psychological levels via structures called chakras. So we may conclude that the aura is an energy field that surrounds the physical body. It encircles each of us as the sun's rays encircle the sun or the halo that surrounds the moon. The appearance of the aura, whether attractive or repulsive, depends on one's physical health, mental attitudes, and spiritual development. The human aura is a dynamic matrix that includes the physical, emotional, and mental-spiritual aspects of self. The aura is the self as energy. All the contributing factors in our daily life register in our aura as colors, lines, dots, emanations, and vibrations. Every one of us is different, and our hidden selves are expressed through the aura. Those individuals who live on a strictly physical, mental, and material level have an entirely different emanation than those individuals who are intellectual and spiritual.
