This book investigates the phenomenon of out-of-body experiences and the possibility of consciousness functioning independently of the physical form. Scott D. Rogo, a researcher in the field of parapsychology, compiles historical accounts, anecdotal evidence, and experimental data to examine whether the human mind can project itself beyond the physical body. He presents a framework that challenges traditional materialist views of consciousness by analyzing reports of astral projection and remote viewing.

Readers often note that the text serves as a comprehensive survey of historical parapsychological literature rather than a modern scientific treatise. Experts in the field of consciousness studies categorize this work as a foundational, albeit speculative, exploration of anomalous human experiences.
