The author of this book aims to correct the misinterpretations that have accumulated over the centuries and this using the older texts, in which he quite right (we would do well to do the same West thing!). Expose the doctrine of the Buddha, that's fine, but issued negative opinions about other religions without having studied the texts, that which seems generator of questions that this book does not answer. In reading, one is tempted to think that God does not exist, but Buddha had the art of not answering questions whose answers were deemed unnecessary in pursuit of liberation, then what should we think? Buddha himself as an instructor and as such, had to help his heart similar to nirvana in this life, putting aside everything that could divert the first goal; there is nothing in this book that does not imply that monotheists are wrong to have faith in their God (okay, reward and punishment, that's not very clever and I'm going in the direction of the author).
I think this book interesting and informative will embarrass readers who read little about religion and it's a shame there was much to remove this book an awkward nothing in my opinion.
