In total silence he perceived a distant melody. It could be coming from the stars, from the bottom of the sea or from the night itself... It was not like any other, not even like the purring of the sea on tranquil nights before the storms... Juan sang drawn by the music that reached him, and, like the night, his song made him brother to the trees, the seagull, the mollusks, the wild flowers that spring up in the sand. "This melody is the murmur of the sea that covers all humankind."
In any activity that requires concentrated effort, the breath quite naturally plays a role. If you have ever tried to thread a needle or repair a watch, you might have observed that without even thinking about it the breath quiets and deepens. Singers, swimmers, people who struggle with panic attacks, and a host of others learn the importance of proper breathing in order to negotiate the respective tasks at hand. Thus, that the art of contemplative practice can be facilitated by the breath should come as no surprise.
