I love books on this type of subject.....except this one. It held my interest for the first few chapters, then it seemed to be just rambling episodes of psychedelic "flashbacks" that are passed off as communications with other beings from other dimensions. The author even admits that some of these episodes may be his own beliefs played out through the hallucinogen. I don't think one "enlightened" person mentioned in the book had "higher" experiences without the aid of some kind of hallucinogenic drug. I'm opened minded about the existence of UFO's, crop circles and aliens, other dimensions, etc., but this book in no way furthers my belief in any of those things. The author has obviously done way to much experimenting with psychedelics for this book to be taken as anything even close to credible.
