If you only see with your eyes and hear with your ears, you'll miss out on a lot.
"Physically you can see with eyes and hear with ears and touch and feel and learn. Through your intellect, you learn most of what you know about the world in which we live. But if you learn by reason only, you will never understand the Spirit and how it works—regardless of how much you learn about other things."
-- Boyd K. Packer, "Personal Revelation: The Gift, the Test, and the Promise"
