Cryptic enough to start the homework

"It's the story of the development of the soul," Miss Portinari was saying at that moment, spreading out the twenty-two trumps or "keys" of that very ancient deck. "We call it a book—the Book of Thoth—and it's the most important book in the world."

George and Joe Malik, each wondering if this was the final explanation or a new put-on leading to a new cycle of deceptions, listened with mingled curiosity and skepticism.

"The order was deliberately reversed," Miss Portinari went on. "Not by the true sages. By the false Illuminati, and by all the other White Brotherhoods and Rosicrucians and Freemasons and whatnot who didn't really understand the truth and therefore wanted to hide the part of it they did understand. They felt themselves threatened; the real sage is never threatened.

"They spoke in symbols and paradoxes, like real sages, but for a different reason. They didn't know what the symbols and paradoxes meant. Instead of following the finger that points to the moon, they sat down and worshipped the finger itself. Instead of following the map, they thought it was the territory and tried to live in it. Instead of reading the menu, they tried to eat it. Dig?

"They had the levels confused. And they tried to confuse any independent searcher by drawing more veils and paradoxes across the path. Finally, in the 1920s, some real left-handed monkey wrenches in one of these mystic lodges recruited Adolph Hitler, and he not only read the book backward, like all of them, but insisted on believing it was the story of the exterior, physical universe."
