Since I am unable to reply to the other flagged/dead comments, I'll add here that the book itself (in the intro. materials and the last chapter) says how one can determine for oneself if it is, in fact, what it says it is, and receive an answer from God. Thus the question becomes not a matter to debate harshly (which has been done enough already), but one of individual knowledge and conscience. I can't prove it to someone else, but it has been satisfactorily proven to me, about which I have written elsewhere at some length.
