Each player must accept the cards life deals him or her: but once they are in hand, he or she alone must decide how to play the cards in order to win the game.
Each of us in our own way can try to spread compassion into people's hearts. Western civilizations these days place great importance on filling the human brain with knowledge, but no one seems to care about filling the human heart with compassion. This is what the real role of religion is.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
