The king had no notion at all what the medicine-guide might be, and asked again and again, until at last the Royal Father-in-Law said: "That monk dispatched from the Land of the East to fetch scriptures — I have looked at him, and his bearing is pure and his countenance well made. He is a true body of ten lifetimes' cultivation, a monk from childhood whose primal male essence has never been spent, and he is ten thousand times better than those small boys."
差 is chāi, dispatched. 為 is wéi, to be, in 自幼為僧. And here is the whole reason Tripitaka is hunted through eighty chapters of this novel: 十世修行的真體, a body carrying the merit of ten successive lifetimes of practice, with 元陽未泄 — the original yang never discharged. Every demon in the book wants to eat him for the same reason, and it is a reason drawn straight from inner alchemy: what has never been spent is worth the most.
This is the sentence the whole novel runs on, and the chapter has been walking toward it since the first goose coop. Tripitaka is not hunted because he is holy in the abstract; he is hunted because ten lifetimes of unspent merit are, in the logic of this world's alchemy, an ingredient.
The chapter has now placed the two valuations side by side. Eleven hundred and eleven children were worth a thousand years because they were young and unblemished. One monk is worth ten thousand times ten thousand for the same reason, raised to a higher power. The arithmetic is the horror, and nobody in the room objects to any part of it.
It also closes the circle on the debate. Tripitaka stood in this hall an hour ago and argued that what has shape must decay and that nothing done to a body reaches the true face. The man who answered him has now proposed to boil that body for soup, on the grounds that it is an unusually good one.
