freedom is the path, vision and finish line...
... all in one, that's how I see it. It's not important for the Fool where he ends up, the important thing is his freedom to do as he pleases. I think he has a vision, and that is his "inner path", that's what he's following. And we've all (?) been there haven't we - you have that vision about where you want to go, not the faintest _practical_ idea of how to get there, but if you just close your eyes, it's right there in front of you, so real you can see it, feel it, touch it and smell it...!
But sometimes that vision in our heart blinds our eyes a bit, so we actually don't see whatever cliffs and other obstacles turn up in our way before we tumble down the mountain and finds ourselves on a whole different track. But the _vision_ is still the same, right? So we keep on moving towards what we want, keep following our inner path - even if the rules of the game have changed a bit...
The main thing about the Fool (as I see him) is that it doesn't really matter.
I work with the World Spirit deck, where the Fool is dancing off a roof top - you can't really make out how in the world she (it's a woman in this case) ended up up there, but she is so full of harmony you can almost feel the freedom of her heart, and sense the vision that forms her "map"...
She says: "Roof tops, cliffs... who cares - I'll get there, that's what's important!"
