... a great book ... it makes a substantial contribution to our understanding of consciousness ... The strength of the book lies in the rich descriptions and analyses of the ayahuasca experience ... deserves to be widely read by those who are seriously interested in understanding the nature of consciousness and reality. Journal of Scientific Exploration The experiences described in this book are quite literally mind-blowing and the cosmic vision it describes will be of great interest to TC readers. Highly recommended. The Cauldron It deserves to be read by anyone interested in religion, mysticism, and conciousness - and who is not? it should be required reading for psychologists, psychiatrists, and neuroscientists, because it shows how absurdly simplistic are the biochemical, darwinianm and genetic models now dominating mind-science.
