Title: Excellent, valuable Mega Resource
Review: This is THE book on Mind machines and technology aimed at helping people take control of their consciousness and mental states. It discusses sound and light machines, biofeedback and a wide range of other technologies. It was way ahead of its time when it originally appeared, and I don't know of any other book that has updated it, other than MegaBrain Zones, also by Mike Hutchison. This book is a great way to get a handle on the technologies available for exploring consciousness.
