Psychiatrist Dr. Brian Weiss returned for a discussion about past & future lives, and the validity of past life therapy. Such therapy has been helpful in healing people from phobias and even medical illnesses. In one case, a woman's cancer went into spontaneous remission, after she did intensive past life work, he reported. In the sessions, he explained, hypnosis is used to deeply relax the clients, who are told to visualize a metaphor such as an elevator or time machine, and to go back to where their symptoms first began. Such methodologies are also employed to take people into the future.
