In the following part of the story Santiago meets an Englishman who is looking for a person, an alchemist, while travelling in a caravan to his treasure. During their journey, the Englishman introduces Santiago to the concept of an alchemist.
The young shepherd later meets and falls in love with a young woman, but abandons her to pursue his dream.
As Santiago travels farther, he meets an Alchemist who teaches him about the universe, explaining omens and how pursuing his dream will allow him to have a good life.
The alchemist aids in him taking the decision by telling the young boy that his heart is alive, talking to him, and it’s alright to have conflicts, because as long as you stay committed to your objective, what you left before will stay there for you when you come back.
This teaches us to follow our instincts and remain committed to our aims since doing so will enable us to go through any difficulties that may come our way.
