Perhaps nothing would be said at first, but eventually a sound, a poem, an artwork or an impression would spark an exchange, and there would be a clear flow of meditative, constructive thought. Periodic silences would follow, to which we both listened almost as if the quiet were a third party speaking to us. And in response to that stillness we would breathe deeply, come to a sort of relaxed attention, and in a humble, reverent manner lower our eyes, as though acknowledging the mystical presence of something greater.
