Centering Prayer

In one of the books I read, Grandma's on the Camino: Reflections on a 48-Day Walking Pilgrimage to Santiago, by Mary O'Hara Wyman, I was impressed with the power the practice of Centering Prayer had on the author. Sometimes Mary would have very difficult, exhausting days, and be tempted to end her pilgrimage. She even fell a few times! But when she'd find a spot to sit and do Centering Prayer, that pause would not only refresh, but also give her the courage to continue the journey. If I remember correctly, Mary was in her 70's and making the pilgrimage to Santiago alone. What an example of the power of prayer!
