" He said that war had destroyed the country and that men believe the cure for war is war as the curandero prescribes the serpent's flesh for its bite. He spoke of his campaigns in the deserts of Mexico and he told them of horses killed under him and he said that the souls of horses mirror the souls of men more closely than men suppose and that horses also love war. Men say they only learn this but he said that no creature can learn that which his heart has no shape to hold. His own father said that no man who has not gone to war horseback can ever truly understand the horse and he said that he supposed he wished that this were not so but that it was so. "
