Chax thought of the sky and what might lie outside of it. He could picture nothing save the ever ascending spire of Botaram, and remembered a time when he and some sharp-sighted comrades tried their best to trace that shining point up as far as they could, to try to see its end. All did their best, straining and gazing until their eyes grew blurry with tears and exhaustion, but all eventually admitted defeat.
He tried another line of thought. Botaram had no end... So if the world itself did have an end, if it didn't go on forever, Botaram must extend outside the world, outside the sky. And what could there be outside the sky, outside the world, in which Botaram could be? He could form no picture. His mind felt surrounded by black impenetrable walls, walls that had no other side and went on forever, and no flash of inspiration came to his aid however he struggled. Soon, with reluctance and relief, he let go of the curious idea. He opened his eyes and saw Aun gazing at him with compassion, and the hint of a smile.
"It's not easy to think about, is it?" said Aun. "It's strange that I'm so uncertain of most things, but somehow this is something I know is right."
