When you look at a human being, you see his hands working, his feet walking, his mouth talking. You don't see his heart, his brain, his lungs and kidneys. They work quietly, inside. But they are the essential organs of life.

The world, too, has hands and feet -- those who are making the news and effecting change. The heart, the inner organs, they are those who work quietly from the inside, those unnoticed. Those who do a simple act of kindness without knowing its reward.
