This book was a spiritual eye-opener. I now look at society, mushrooms, and the world from a completely different perspective. I read the book aloud to my wife, and Terence McKenna's prose filled the room with as much weight as the little voices in your head. A remarkable read from a remarkable man. We actually passed this book on to a friend who was interested, and are moving on to another of McKenna's books as well as a spoken-word/music CD. Highly recommended to anyone with an open mind and the ability to question ones own reality (just remember that you create your own reality).
