The Daishonin writes, “A Buddha is looked up to as the Hero of the World” (WND-1, 835). A hero of the world is a person who is courageously engaged in the realities of life and society. A Buddha is one who intrepidly battles devilish functions and, manifesting the life force of the world of Buddhahood, leads a life of right action in human society.
