Answer: Santiago discovers that the Soul of the World is within everyone and everything.
Explanation: Santiago, a young man from the "Alchemist" novel, embarked on the way to the Egyptian Pyramids to follow his dream. He stayed in some places for some time, learning things that would help him to realize his Personal Legend. He met many people who helped him in this learning. One of these encounters was with the ancient alchemist who sent him to the secrets of the world and the Personal Legends. The most important lesson he learned from him, as he turns into the wind, is that there is a universal soul in the cosmos, which is the driver of all events, and which is found in all people and things, which is pure love.
