All meditation aims to bring the person, mind and body to silence, stillness and simplicity of spirit by means of an inner "object of attention". The act of attention is the inner sacrifice, and the work of paying attention is the school of letting go. The utter simplicity of such a way to joy and peace makes one laugh. God seduces us by simplicity.
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.
