Silence brings us back to basics, to our senses, to our selves. It locates us. Without that return we can go so far away from our true natures that we end up, quite literally, beside ourselves. We live blindly and act thoughtlessly. We endanger the delicate balance which sustains our lives, our communities, and our planet.
Call the world if you please, "The Vale of Soul Making." Then you will find out the use of the world.
