Because the book that descends is not the same book that was hovering so peacefully in the empyrean. The book that descends is never that same book. It’s rather like a parody or satire of that book, but it’s not funny. Or it’s not funny to you.
The book that you now have in front of you, worded onto the page, or onscreen, is just a beaten ugly incarnation of its original perfect being, and it’s your fault. You have only yourself to blame. Because you couldn’t control yourself. Because you just couldn’t have left it twinkling in the ether. You had to call it down, you were so afraid, so jealous, that someone else might possess it. But now it’s yours, it’s all yours, a justly perverse reward for your needy greed and hubris. Now, instead of perfection, you possess a monster.
