The secret of life? Love God with all your heart. What does this actually mean? It's really very simple. Follow the heart's natural desire to look upward in worship. This should be the dominant fact of life, gravity being the dominant fact of existence. It doesn't mean that you're always gazing upward or thrusting your chest up and out, but it does mean that there is always a tendency – a desire – behind the quotidian, to lift, to lightness. A quiet moment should always bring you back to this feeling.
