So here's what Waite says: "The rapture of the world when it understands itself in God." "The state of the soul in the consciousness of divine vision reflected from the self-knowing spirit." And some other spooky stuff, but it's how the Fool sees the world, in all his wisdom. As an obstacle it must mean a perceptual error, but I'd have to see the rest of the reading before I could say more than that. When looking at that circular reef remember: when you look at zero you see nothing, but when you look THROUGH zero, you see everything. Mic drop.
