Reincarnation is a belief that has caused controversy for a long time: rejected by the Christian religion and accepted by the Eastern religions, it has always aroused great interest. Today, even science is delving deeper into this subject. Sometimes, through fleeting impressions or dreams, one experiences the sensation of remembering a previous life. In this book, Roger Luc Mary, a specialist in paranormal phenomena, invites us to recognize our other history. To achieve this goal, he presents the theories of reincarnation in religious traditions, the psychological and emotional processes that are the basis of memories and propitious states of consciousness. In short, a book to better understand what Blaise Pascal meant when he said: "The whole succession of men must be considered as one and the same man".
