aura

Some people believe that there is a visible energy field, called an aura, that can be seen or otherwise sensed around living beings—especially around humans. In Hindu cosmology, there are multiple fields and these are interpreted as kosa of pranic energy. Auras reflect the spiritual and physical nature of a person.For example, a dark bluish to black area supposedly seen by psychics surrounding the chest is indicative of lung cancer. Auras may be attributed to biologically based electromagnetic fields.These energy fields are sometimes claimed to be documented by a rare form of photography called Kirlian photography. However, these claims are vigorously denied by skeptics about paranormal activity. James Randi, for example, has for many years (as of 2004) offered one million US dollars to any person capable of repeatedly detecting auras, and no person has ever stepped forward to claim the prize. The test involves a simple task.
