This popular science publication contains almost all studies on the possibility of the existence of the soul after death, both already known and new. What happens to the soul on the 3rd, 9th and 40th days after the death of the body from the point of view of physics, medicine and metaphysics, how the soul itself feels what is happening - you will find the answers to these questions here. The author creates a complete and reliable picture of the wanderings of the human spirit from the moment of death to the subsequent incarnation. The book analyzes already known research in the field of medicine, research based on the system of regressive hypnosis and sensory deprivation, provides the author’s own psychological and physiological research on this issue, as well as the views of the Orthodox Church and the “Tibetan Book of the Dead”. The book is based in part on the research of Raymond Moody (Life After Life) and Michael Newton (Journeys of the Soul), significantly expanding and continuing them. Does not contain references to astrology and unverified esoteric writings.
