This book is written by a wise old man with a youthful heart. If you accept the idea that transcendence is part of the fundamental nature of our universe, you are ready for this book. If you do not I recommend E.F. Schumacher's "Guide for the Perplexed", and Ken Wilber's "A Theory of Everything." Pearce makes extraordinary progress at integrating brain research, physics, the teachings of Jesus, mystical experiences, human developmental stages, and practical everyday living. Though the ultimate message--that we live best when we live from our hearts--has been repeated many many times; no one has ever said it with such intricate physical explanations. The contents of the book constantly push the boundaries of knowledge and understanding, and as a result it leaves more questions than it answers. The book is an extraordinary leap forward that begs for further research, evidence and practice.
