This image conects to the Alchemists because, Santiago and the Englishman traveled to thier journey through the desert in a caravan. And the Englishman learned an important thing about the caravan. He learned that the caravan is a symbol of persevierence, because it has a place where it goes, kind of like a destiny, or a goal, which I bet everybody has a goal to reach, even though it goes through some obsticles it doesnt stop or go somewhere else. And thats what everyone should do, which is to follow your goal, dream or destinations even if you come to an obsticle you go around it like the caravan did with the big rock but it still returned to going straight yo its destiny.
