In search of a healing method that encompasses the complexity of human beings, Erika Isolde Schäfer discovered reincarnation therapy. Particularly with children, the best results can be achieved, as they still have an unreserved access to the topics of death and rebirth. In "Mama, believe me, I have lived before," one can experience the great wisdom of our soul. This is evident in the images that children paint in remembrance of their past lives. Our soul forgets nothing, and the memories leave traces in our bodies as well. With this approach, it is possible to find a path out of emotional and physical illnesses in conjunction with other forms of therapy and schools of thought. The author's aim is to inspire parents and professionals to collaborate across all disciplines and to open their eyes to this possibility.
