This book is unexpected. Don Miguel write a clear and accessible book. The goal is probably to get the message. There I liked the book of P. Ras which made the connection with the monotheistic religions, philosophy, psychology, etc. it gives back. So, I better hit on certain aspects of Don Miguel Rivs agreements. And the author does not stop there. It provides a summary: "consider every problem as an experiment" ... With exos practice! Concrete and effective! The icing on the cake was the interview with the nagual Don Manuel Aquilo.
