In parapsychology and spiritual practice, an aura is a field of subtle, luminous radiation surrounding a person or object like the halo or aureola in religious art. The depiction of such an aura often connotes a person of particular power or holiness. It is said that all objects and all living things manifest such an aura. Often it is held to be perceptible, whether spontaneously or with practice: such perception is at times linked with the third eye of Indian spirituality.[1][2] Various writers associate various personality traits with the colors of different layers of the aura.[3][4][5] It has also been described as a map of the thoughts and feelings surrounding a person.[6][7]

Skeptics such as Robert Todd Carroll contend that people may perceive auras because of effects within the brain: synesthesia,[8] epilepsy, migraines, or the influence of psychedelic drugs such as LSD.[9][10] Other causes may include disorders within the visual system provoking optical effects. Eye fatigue can also produce an aura, sometimes referred to as eye burn.

In the temporary use of language there is the word "Aura", but the meaning can be quite different. For many people, the Aura is only the radiance of human beings. For scientists, it is a concrete, existing energy field that surround living creatures. The Aura is formed by subtle color radiances which surround the body of a human being. These radiances can be perceived by a psychic. Each color signifies a certain vibration which has different meanings.

The Aura, which is connected with the activity of the chakra (Sanskrit for "energy wheel"), reflects the individual state of consciousness. In that case, the colors of the Aura give us information about the quality of consciousness, as well as one's emotions, thoughts, abilities and the vital energies of a person.

The history of Auras goes far back into the past. Natural tribes, the Christian Mystics of the Middle Ages, painters, and artists of all ages have shown the Aura in a radiant, shining ray of lights around human being, animal or plant. This information, which can be perceived by sensitive and psychic people, has been researched and proved scientifically in the last decades. Modern scientists measure the Aura as a electromagnetic field around living creatures.
