French monk (and former scientist in cell genetics) Matthieu Ricard speaks about science, meditation, and his title as 'the happiest man in the world.'
"By activating some areas of the brain, you could possibly generate a sensation of intense pleasure for a while, but that’s not going to last forever. That’s definitely not happiness. It is just a temporary gimmick. Genuine happiness is a state related to wisdom, to being attuned to reality, and to freedom from mental toxins (hatred, craving, and the like). Pleasure by itself has no reason to engender freedom from ignorance, dualistic clinging, and distortion of reality (true causes of suffering). There is nothing wrong with pleasure in itself, but it does not have much to do with happiness."
