Can a book by a spiritual leader become a bestseller, a textbook of life for all people, regardless of religion? Yes, perhaps, and the best proof of this is The Art of Being Happy by the 14th Dalai Lama. In this book, he answers the questions of psychotherapist Howard Cutler from the point of view of Buddhist philosophy. Since its first publication, the book has gone through 10 reprints, and the principles set forth by the Dalai Lama have received many scientific confirmations.
