I think the most essential thing in one's life is silence. What is silence? We think if we are quiet, we are silent. But we must come to silence without desire and wanting, otherwise we are not silent.
Peace is love resting in order to be renewed. The renewal takes place in the inner silence. In the desert we see things as they are. We are face to face with reality. The silence we observe externally does then become also the inner silence when the miracles of grace take place. Here we are stripped of the outward garments hiding our true selves. Here we can embrace the awfulness of our human condition and the awesomeness of the offered gift of grace. We are in touch at last with our reality.
