Unless we are rooted in God, and rooted in the only sure way of listening to God -- namely, silence -- then we are doomed to spend our lives standing at the window of life and watching the world go by... It strikes me that most of the first part of our lives is spent filling our heads with information. The last part -- and the most important part -- is spent emptying our heads of all the trivia so that our hearts may be free to learn wisdom -- in silence.
Many of us need the wilderness as a place to listen to the quiet, to feel at home with ancient rhythms that are absent in city life, to know the pulse of a river, the riffle of the wind, the rataplan of rain on the slickrock.
