A classic in the matter

One must have read this book which described his time in completely new and amazing phenomena. Since many books have been published about this mysterious passage, the tunnel, the light, the presence of relatives or benevolent entities ... The preface of Elisabeth Kubler Ross complements the book. It's easy to read, a little repetitive at times, but this is the book that has had the courage and the merit of talk about "these things" in a time when parapsychology was not up to date. A classic of sorts.
