“ And then it struck him what lay buried far down under the earth on which his feet were so firmly planted: the ominous rumbling of the deepest darkness, secret rivers that transported desire, slimy creatures writhing, the lair of earthquakes ready to transform whole cities into mounds of rubble. These, too, were helping to create the rhythm of the earth. He stopped dancing and, catching his breath, stared at the ground beneath his feet as though peering into a bottomless hole. ”
