In the book “The Alchemist” by Paulo Coelho, Santiagogoes on a journey after he has a dream to find a treasure of gold. On his journey he meets different people who help him along the way. One of the people that Santiago meets is a Crystal Merchant. He works for the merchant in his shop as he tries to earn money for his trip.
Working for the merchant is not very pleasant. The man is grouchy and always complains, but he is fair to Santiago. For every piece Santiago sells he gets a part of the sale. Santiago wants to build a cabinet to display crystal for customers who pass by to see. The merchant is insecure about change. Santiago learns that change is necessary for success and if one never changes, one never moves forward.
The second thing that he learns is not to put off something one intends to do. The merchant tells how he is a devout Muslim but he has never made the pilgrimage to Mecca, because he was always afraid to trust his shop with anyone. Yet, it is something he has always wanted to do.
He also learns that not everyone can see his dreams come true in the same way.
He has learned how to deal in crystal and how to understand language without words.
Santiago also comes to realize that he has to listen to and identify the clues and omens around him.
One of the most important things that he is starting to realize is that he was stagnant in his life as a Shepard. The sheep had already taught him. They could not teach him anything new, but by making his journey and meeting new people, he was learning new things.
