"A tale is told of a teacher and his disciples watching a tightrope walker who was so absorbed in what he was doing that they asked their teacher what it was that riveted the aerialist's gaze to this seemingly foolish performance. The teacher answered, 'I cannot say why this man is risking his life. I only know that while he is up there, he is not thinking of the gold coins he is earning by walking the rope--for if he did, he would fall."
