I bought this book after seeing an interview with Eric Pearl on Gaiam TV "Inspirations." I'm glad I paid only $5 because the book doesn't tell much more than the story he told during the interview.Above all, I bought it to see if this kind of healing is worth a try, but the book doesn't have any proof that it works, so why would I throw away $300.He mentions one study in which the participants could "feel" that energy work was being done on them, but that doesn't really mean that it works.I dont know what to make of this, part of me feels like it could be fake, but then why are his seminars so popular?
