Because Buddhism is one of the world’s great thought-systems, full of profound philosophical and psychological as well as "spiritual" insights which influence people to this day, whether they call themselves Buddhists or not. Because Buddhism is relevant to everyone. At its core it is about how to live a wise, compassionate and fulfilled life. How to make the world a more harmonious place. How to become enlightened. In short, how to be happy.
