Petey Silveira was trained in past-life regression therapy by Dr. Brian Weiss, author of Many Lives, Many Masters. This work takes place in hypnotherapy, where the client goes back to a past life and speaks about their experiences in that lifetime. The theory of reincarnation is that the soul, upon the death of the body, comes back to earth in another body. Essentially, it is the belief that there is a rebirth of the soul in a new body. If negative events happened in a previous lifetime and left a harmful imprint on cell memories carried over into this lifetime, the event may have created symptoms that have clients seeking therapy today. Petey has written a book, Stepping Into My Happiest Lifetime, about a former client who found healing using this method. Clients do not have to believe in past lives to achieve healing from this experience. Dr. Carl Jung teaches us about the collective unconscious. He believes that each person can tap into their unconscious to access their stories as metaphors, and the metaphors will create healing for that person. Petey can guide clients through the dysfunction that took place and got stuck in their cell memories. Past-life regression work is a viable option even for clients who do not believe in past lives. The power of the process is you deciding whether or not this is an avenue of healing you want to explore.
