The tourist sees what they came to see; the traveler sees what is actually there; the sage sees what the place is trying to say. Nasreddin traveled constantly and seemed to carry his village with him everywhere, which is both the advantage and the limitation of traveling with a mind already full. The best journey is the one that changes the traveler; the second-best is the one that reveals which parts of them could not be changed.
Each step builds on the last.
