In Proof of Heaven , a neurosurgeon has a near death experience which contradicts his lifetime of studying science and medicine. In dealing with his patients, Dr. Alexander has always gently explained away afterlife events as hallucinations, or any number of injured brain illusions. But then it happened to him. Now he is in the unique position of being a scientist/neurosurgeon and having an unbelievable experience in the great beyond to report, explain and understand. This fascinating book takes us on that afterlife journey with Dr. Alexander.
