When you observe a human being, you can see their hands working, their feet walking, their mouth speaking. You cannot see their heart, their brain, their lungs, and kidneys. These work silently, in a hidden way. Yet they are the essential organs of life.
The world, too, has feet and hands—those that make the news and generate change. The heart, the internal organs, are those that work silently from within, those that go unnoticed. Those that perform a simple act of kindness without knowing the reward.
