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.
This was my first conscious experience of listening to Gaia, even though I didn't call it that then or hear an actual voice... I have come to learn that there are many ways of listening. One may hear an internal or external voice, feel a body sensation, or simply just "know" with that intuitive understanding that is beyond words. However, I continue to describe this experience as "listening" because we have forgotten how to be silent and listen to ourselves, one another, and the earth.
