To be honest it's not worth a 4 star review. Yes, it's quite insightful to learn and practice few of enlightening exercises taught in the book, but that wouldn't be enough to give ita 4 or 5 star rating. If you're religious and would like to seek motivation and inspiration from religious context then this is the book for you. Else read only to enjoy fee bits and pieces of it. Like imagining the way author describes Europe or narrates medical history to make a point.
