The spirit of the wilderness is solitude. We go alone to meet the divinity within us. The wisdom of the wilderness comes from God interacting through creation to touch our very soul. We emerge from our journey with a new identity grounded in God. Transformed, we discover we have been given back to ourselves.
God is the friend of silence. See how nature -- trees, flowers, grass -- grow in silence; see the stars, the moon, the sun, how they move in silence... The more we receive in silent prayer, the more we can give in our active life. We need silence to be able to touch souls. The essential thing is not what we say, but what God says to us and through us. All our words will be useless unless they come from within.
