"I see a light," he said to his wife, "and I hear a sound. I fear that I am possessed." This idea was most distressing to a pious man. He became pale, haggard; he wandered about on the hill near Mecca crying for help to God. More than once he drew near the edge of the cliff and was tempted to hurl himself down, and so put an end to his misery at once. He lived much in the open air, gazing on the stars, watching the dry ground grow green beneath the gentle rain. He pondered also on the religious legends of the Jews, which he had heard related on his journeys; and as he looked and thought, the darkness was dispelled, the clouds disappeared, and the vision of God in solitary grandeur rose within his mind, and there came upon him an impulse to speak of God. There came upon him a belief that he was a messenger of God sent on earth to restore the religion of Abraham, which the pagan Arabs had polluted with idolatry, the Jews in corrupting their holy books. At the same time he heard a Voice, and sometimes he felt a noise in his ears like the tinkling of bells or a low deep hum, as if bees were swarming round his head. At this period of his life the chapters of the Koran were delivered in throes of pain. The paroxysms were preceded by depression of spirit, his face became clouded, his extremities turned cold, he shook like a man in an ague, and he called for coverings. His face assumed an expression horrible to see, the vein between his eyebrows became distended, his eyes were fixed, his head moved to and fro, as if he was conversing, and then he gave forth the oracle or Sura. The hitherto mentally and emotionally normal trader, husband, and father was thus suddenly swept off his feet and carried irresistibly away on a mighty tide. His perturbed spirit now soared to the heights of Heaven, now plunged into the chasms of hell. Moments of ethereal bliss would be followed by periods of profoundest melancholy.
