The Fool comes upon a Tower, fantastic, magnificent, and familiar. In fact, The Fool, himself, helped build this Tower back when the most important thing to him was making his mark on the world and proving himself better than other men. Inside the Tower, at the top, arrogant men still live, convinced of their rightness.
Seeing the Tower again, the Fool feels as if lightning has just flashed across his mind; he thought he'd left that old self behind when he started on this spiritual journey. But he realizes now that he hasn't. He's been seeing himself, like the Tower, like the men inside, as alone and singular and superior, when in fact, he is no such thing.So captured is he by the shock of this insight, that he opens his mouth and releases a SHOUT! And to his astonishment and terror, a bolt of actual lightning slashes down from the heavens striking the Tower and sending its residents leaping out into the waters below.
In a moment, it is over. The Tower is rubble, only rocks remaining. Stunned and shaken to the core, the Fool experiences profound fear and disbelief. But also, a strange clarity of vision, as if his inner eye has finally opened. He tore down his resistance to change and sacrifice (Hanged man), then came to terms with Death (Death); he learned about moderation and synthesis (Temperance) and about power (The Devil). But here and now, he has done what was hardest: he destroyed the lies of his life. What's left are the foundations of truth. On this he can rebuild himself.
