Query: Happiness by Matthieu Ricard

Happiness: A Guide to Developing Life's Most Important SkillThis is the best book I have ever read on the subject of happiness. A real treasure.Happiness is not a mystery but a possible goal for anyone who seriously wants to become a happier and better person. If you love science, literature and culture, Matthieu Ricard is the right guru for you.A must read for everyone who loved his book "The Monk and the Philosopher".A book you won't ever part with for you'll want to read in it again and again.Inge Hohndorf
