I found Madaus's recounting of his experiences at TMI (The Monroe Institute) the most engaging part of the book. He never discusses how to reach different states, only his experiences with them. It's a fascinating read (although it's hard not to be jealous at how much of a natural he was and how quickly he progressed).
I finished reading this a couple of weeks ago. It was an enjoyable read and as mactombs says, I liked the TMI experiences the most.
I would happily recommend this to anyone on these boards.
