From the time I heard about this book, I was quite interested in reading it. It is, however, not that easy to find. I got this one through inter-library loan. Apparently, (I got this from Wikipedia) the titular Guru, John-Roger, was given the copyright to this book as part of a settlement in a libel trial and McWilliams tried to have all copies taken out of circulation.
McWilliams, who wrote the feel good Life 101 books, uses his distinctive bouncy narrative with tons of pull quotes. The topic he says he will explore is how an intelligent, rational person can get taken in by religious programming by a spiritual con artist. That could make for a fascinating and enlightening read.
Unfortunately, McWilliams did not wait long enough to gain the proper perspective on the situation. He was actively fighting with this ex-guru as he wrote the book, so rather than using his specific situation to highlight the more general topic, he focuses far too much on John-Roger and his ministry and shortcomings. McWilliams was free from the notion that his guru was a god, but he was every bit as much in his thoughts as his adversary.
Having been through a lawsuit myself, I understand the emotional need, especially of a writer, to try to "set the record straight" and "have the last word," and those impulses are very much on display here.
There is some interesting gossip about Arianna Huffington, who was according to McWilliams, a John-Roger devotee.
The book has its good lines and observations, and is fairly entertaining, but I didn't leave feeling as though I had a much greater understanding of how a person becomes "programmed." Instead I knew a great deal about John-Roger as told by someone who felt hurt and betrayed by him. Kind of an interesting character, but not that interesting. That kind of spiritual trickster is a familiar character.
Maybe the reason the story felt a bit flat, and lacking in depth, is because McWilliams hadn't put enough distance between himself to be quite able to express the love that he had felt before he felt betrayed. He didn't describe his experience of joining the movement with the fresh eyes of someone who did not already know he was being programmed. This is understandable given where he must have been when he wrote it, but I think there might have been a more emotionally compelling story there had he taken it on when it was not so fresh.
