The Great Handbook of Reincarnation offers comprehensive insights into regression therapy, which is considered an effective method for healing physical and psychological issues. It explains how many illnesses and difficulties can have their roots in past lives. By uncovering these causes, spontaneous or gradual healings can often be achieved, even when traditional therapies fail. The guide addresses key questions about regression therapy, such as the necessity of believing in reincarnation, the execution of the therapy, and its combination with other healing methods. This handbook is aimed not only at medical professionals and therapists but also at anyone interested in holistic healing and wishing to deepen their own experiences with regression therapy.
