In this astonishing work, Carlos Castaneda at last completes the long journey into the world of sorcery that began with his now-legendary meeting with don Juan. Drawn back by the knowledge that the sorcerer's task has not been completed, Castaneda returns to plumb the final, awesome secrets of the sorcerer's explanation of the world-to learn, in don Juan's world and his own, the last lesson of a unique and arduous apprenticeship. For until now don Juan has performed his acts of power in his world, the dry, barren deserts and mesas of his birth, a world in which he seems to exist as naturally as the chaparral and the rocks. Now, in an unexpected encounter, don Juan appears in Castaneda's modern urban world, at ease in a well-tailored suit, demonstrating his lessons of power in the crowded, busy streets, using the city scene, as he uses everything, to unfold the wings of Carlos Castaneda's perception.
