When was the last time you heard silence? Total and utter silence — not only in your surroundings — but also within. That stuff is hard to come by these days. And for the past 200 years, since the beginning of the industrial revolution, it has become harder and harder, every day. On my quest to find the world’s silent spaces, I was drawn to places of worship and to vast natural spaces—where people seek inward instead of outward, reconnecting with themselves and with greater forces— and to capture the ambiance radiating from these places, to discover what has been lost on the way to modernity.
