This book is the 4th in his school of life series. It uses quotes from the first three books, explains each quote in turn, followed by an interpretation of it and then an exercise meditation to practice that idea.

I found the quotes to be thought provoking and interesting. I agreed with all of them, if not all the details of the explanations. I feel the exercises would be useful and helpful for further self understanding and enlightenment. There is a bit of a focus on Christian religion, though many quotes seem more Buddhist in nature. I feel the book could be a useful tool in self development.
