The Alchemist conclusion
     This ending for the book shows us that Santiago had the treasure under his foot the whole time. One of the  refuges told him that in the exact spot that Santiago's dream told him to go he had a dream that said the treasure is under a tree in Spain where Santiago came from. Its a return home for Santiago to someplace technically he never had to leave in the first place, but then he never would have had this trip. He doesn't get mad when he hears this news he gets over joyed because he too knows the trip was worth it. He found something to believe in, He found his personal legend, and he found love in the deserts of Egypt a love that does not make him content with his life but instead actually chase after his personal legend. So this ending bring the point home that its not the destination that you got to but the journey to get there.
