The book is written by a Western MD and focuses heavily on results. It leans on the classical maps of the path of meditation from Burmese Theravada, a tradition that is about as stripped down and non-theistic as it gets. That said, the maps and some of the terms used may appear somewhat archaic to a modern reader.
