What does it mean to bring peace to the world and virtue to people's hearts?

"Law stabilizes the world, morality nourishes people's hearts" means that law can stabilize things in the world, and morality can nourish people's hearts. Law is a code of conduct formulated and enforced by the state, while morality is a code of conduct adjusted by people's inner beliefs, traditional habits and ideological education. It shows that national and social governance require law and morality to play a simultaneous role.
