Imagining the Unimaginable is an inventor’s journey to answer age-old questions from a modern-day perspective using only first-hand human experiences. When a system engineer and inventor of over one-hundred and twenty US patents analyzes and models the afterlife from only first-hand evidence culled from thousands of Near-death experiences (NDEs) and past-life regression hypnosis sessions, a divine system emerges. After nearly dying from a blood clot in 2004, author and inventor Richard Rowe began a spiritual journey to answer age-old questions: What happens after we die? Is there an afterlife? Why is there so much suffering in the world? Why do bad things happen to good people? To answer these questions and many others, Richard uses over thirty years of inventing and system engineering experience to examine insights from first-hand NDEs. When his questions get deeper, Richard must search beyond NDEs for answers. He expands his reference material to the first-hand reports of people under past-life regression hypnosis, then goes one step further and includes insights from personal experimentation with past-life regression hypnosis. Unlike existing books covering the topics of NDEs and past-life regression, Richard synthesizes a vast amount of first-hand information and develops an overarching model to account for the data using easy-to-understand diagrams and explanations to infer and describe an inventor's perspective of heavenly realms orchestrating the afterlife.
