Query: Good book

I will agree with some of the others; this is a great book if you're vaguely familiar with some of the concepts. If you've never heard anything about buddhism except the name, this may not be the best place to start. What it did for me was to clarify some of the concepts I had read about in other books that those authors did not elaborate on, either for lack of room or their belief you already understood the concepts. I did find this to be a fascinating read. Some of it in other ways gets repeated in other books on the subject to varying degrees, but this is a bit more simplified. Well worth the read.
