Years ago, I was at a workshop with mythologist Joseph Campbell, and he was showing us pictures of the sacred. He showed us this wonderful bronze statue of the god Shiva, dancing. Inside a ring of flame the god was dancing. He had one foot in the air, and the other foot resting on the back of a little man, who was crouched down in the dust, giving his full, absorbed attention to something he was holding between his hands. I asked Joseph Campbell, "What is that? What is that little guy doing down there?" Campbell said, "That's a little man who is so caught up in the study of the material world that he does not notice that the living god is dancing on his back."
