Imagine yourself sitting on the edge of a cliff looking out across an ocean. It is just before the dawn on a warm summer's morning. All around you is still and soundless. Just slivers of starlight sparkling off the waves below saves a pitch-blackness. A warm breeze drifts across the ocean and wafts up the face of the cliff and into your heart, and this breeze is not so much a movement of air but a feeling; a feeling of peace.
