I have been listening to both sides and I have read most of the book and listened to most of the podcasts of the class. I believe that is the only way you can give your opinion about the book. Most critics are only regurgitating what others have said (who have also probably not read it). The "classes" and book clubs are places for discussion from all sides (not put downs or calling for the end of the world). When I think that I want to criticize someone, the first place I go is to find out what they are all about. If you see that person as an enemy then you must know your enemy (and I believe Jesus said to love your enemies). And if you have REALLY read the book then you will know that the techniques to deal with your personal problems have absolutely nothing to do with religion. So far the information in this book has helped me tremendously with my marriage and helped me focus on what is really important.
