I liked this book! Mostly because I'm in sort of the same situation as Weiner. To tell you the truth, I was curious about what he would say about Kabbalah, so I finished reading his experience of Toaism and skipped to the last chapter of Kabbalah. I was impressed, and it renewed my devotion to Kabbalah! I studied it at The Kabbalah Centre in New York (I grew up in a Christian family, and much of it didn't make any sense to me), and then after hearing from a few friends who are also a part of the mega-association that I wasn't spiritual anymore (not being spiritual translates into not paying for classes and not talking in some Kabbalah dialect makes you non-spiritual. WTF?). I was impressed and happy with Kabbalah after reading his experience. I was also able to reach a conclusion about my own opinions of it. It's not the teachers or the teachings, but the students who become more self righteous about it!
I also enjoyed reading about the Realian thing, which I never knew existed (I thought Scientology was the only spirituality with Aliens, as I found out later, there are more that I just didn't know about). I love his honesty, and his search on the source of different spiritualities, and asking the BIG question with all of them "Why?"
