Query: A solid work, worth the read.

John R. Violette elegantly portrays a vision of reality with simple yet powerful analogies. Using 2-dimensional "plane-beings" as examples, he explains how various paranormal phenonemon can occur, and how we can perceive ourselves existing in in a slice of higher-dimensional space.While encompassing a wide spectrum of concepts and issues, a sense of coherence is held throughout the book, carrying the reader on a convincing journey into the heart of the "extra-dimensional theory".The book is tied off in a satisfying, uplifting manner, providing a conceptual framework of the universe which incorporates many existing theories and beliefs.Highly recommended for anyone who is interested in furthering their understanding of the world they exist in.
