Beauty.
“Beauty is a key to the mystery and a call to transcendence. It is an invitation to savour life and to dream of the future. That is why the beauty of created things can never fully satisfy. It stirs that hidden nostalgia for God which a love of beauty like Saint Augustine could express in incomparable terms: “Late have I loved you, beauty to old and so new: late have I loved you!” (Letter to Artists, 16)”
