Discussion extremely fluid and pragmatic for a difficult subject to deal with and that lends itself to the most extremely remote philosophical and intellectual digressions from everyday reality. Matthieu Ricard proposes an approach more than a set of ready-made, which leaves each be the choice of its way to authentic happiness. It shows that it has nothing to do with the momentary satisfaction of pleasure and more or less pressing desires. The book is a splendid oriental philosophy alloy and a mode of analysis feature of the West in its greatest brilliance. Just great, I highly recommend it to anyone looking for change and personal growth.
