" One of my practices comes from an ancient Indian teacher. He taught that when you experience some tragic situation, think about it. If there’s no way to overcome the tragedy, then there is no use worrying too much. So I practice that. (The Dalai Lama was referring to the eighth-century Buddhist master Shantideva, who wrote, “If something can be done about the situation, what need is there for dejection? And if nothing can be done about it, what use is there for being dejected?”) "
