X-6o expresses in the divine world predestination: in the intellectual world Mystery: in the physical world the Unforeseen, Fatality.
Arcanum XV is represented by Typhon, the spirit of catastrophes, who rises out of a flaming abyss and brandishes a torch above the heads of two men chained at his feet. It is the image of Fatality which bursts into certain lives like the eruption of a volcano, and overwhelms great as well as small, strong and weak, the cleverest and the least perceptive, in its equal disaster.
Whoever you may be, son of Earth, contemplate the ancient oaks that defy the lightning, but which the lightning strikes after having avoided them for more than a century. Cease to believe in your wisdom and your strength, if God has not granted that you may receive the key to the mysteries that make a prisoner of Fate.
