Psychiatrist Dr Brian Weiss had been working with Catherine, a young patient, for eighteen months. Catherine was suffering from recurring nightmares and chronic anxiety attacks. When his traditional methods of therapy failed, Dr Weiss turned to hypnosis and was astonished and sceptical when Catherine began recalling past-life traumas which seemed to hold the key to her problems. Dr Weiss's scepticism was eroded when Catherine began to channel messages from 'the space between lives', which contained remarkable revelations about his own life. Acting as a channel for information from highly evolved spirit entities called the Masters, Catherine revealed many secrets of life and death. This fascinating case dramatically altered the lives of Catherine and Dr Weiss, and provides important information on the mysteries of the mind, the continuation of life after death and the influence of our past-life experiences on our present behaviour.
