Why do you think coelho chose crystal?

Paulo Coelho chose crystals in his works, particularly in "The Alchemist," to symbolize clarity, transformation, and the pursuit of one’s dreams. Crystals, with their unique structures and natural beauty, reflect the idea of personal growth and the journey of self-discovery. They also serve as a metaphor for the inner light and potential that each individual possesses, emphasizing the importance of recognizing and harnessing one's true self. Through this imagery, Coelho encourages readers to embrace their individuality and seek their own paths.
