God is not a topic common to Buddhism so when a well known Zen Buddhist monk writes a book about the subject, it'll probably have interesting insights. That's the case with Brad Warner's new book "There is No God, and He is Always With You". Even atheists are very interested in God and I think many of us can and do enjoy the discourse about this topic.
It is a fascinating book that comes from the Zen and Buddhist way of looking at life and the cosmos. I think you'll enjoy the unique discussion of this point of view.
