Visual Auras – Parapsychological Definition:
Auras are fields of subtle, multicolored, luminous radiations said to surround living bodies as a halo or cocoon; the term is occasionally used to refer to the normal electromagnetic field forces surrounding the body.
[Latin, from the Greek, “breath of air”]
A type of high-voltage, high-frequency photography, developed in the Soviet Union by Semyon Davidovich Kirlian, which records on photographic film the so-called “corona discharge” of an object caused by ionization of the field surrounding that object; it is claimed by some that this process indicates the existence of hitherto unknown radiations or energy fields such as “bioplasma” or the “psychic aura.”
