The one thing all humans have in common is that each of us wants to be happy, says Brother David Steindl-Rast, a monk and interfaith scholar. And happiness, he suggests, is born from gratitude. An inspiring lesson in slowing down, looking where you're going, and above all, being grateful. David Steindl-Rast is an American Catholic Benedictine monk, author, and lecturer who has spent time in various monastic communities. His experiences from around the world and with the world's various religions convinced him that the human response of gratitude is a part of a religious worldview and is essential to all human life.
