An aura is the energy field that is believed to surround every living being (including plants and animals). Most of the time, the aura is seen as layers of color around the subject.
In parapsychology and many forms of 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. Sometimes, however, it is said that all living things (including humans) and all objects 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.
