The VERITAS Research Program of the Laboratory for Advances in Consciousness and Health in the Department of Psychology at the University of Arizona, run by the parapsychologist Gary Schwartz, was created primarily to test the hypothesis that the consciousness (or identity) of a person survives physical death.[189] Schwartz claimed his experiments were indicative of survival, but do not yet provide conclusive proof.[190][191] The experiments described by Schwartz have received criticism from the scientific community for being inadequately designed and using poor controls.[192][193]
A clairvoyant medium is a psychic who goes into trance, a sleep like state in which he allows his body and senses to be possessed by the spirit which may be his own guiding spirit or that of the seeker. The spirit has an overview of all the happenings on the earth. A clairvoyant medium can speak while lying down. He can also sit down or even walk and make gestures by moving his hands. He can even write or type his messages.
