In Paulo Coelho's The Alchemist, Melchizedek, the King of Salem, is speaking with the boy about how to obtain one's Personal Legend. One's Personal Legend is fulfilling one's full potential in life. For Santiago, he must find his treasure at the Egyptian pyramids as told to him in a dream. He must go on a journey, though, and this journey is where he discovers more about himself than just searching for treasure. Melchizedek explains that one's Personal Legend is different for everyone and we all know what it is when we are children. However, the following eventually occurs:
"But as time passes, a mysterious force begins to convince them that it will be impossible for them to realize their Personal Legend. . . It's a force that appears to be negative, but actually shows you how to realize your Personal Legend. It prepares your spirit and your will, because there is one great truth on this planet: whoever you are. . . when you really want something, it's because that desire originated in the soul of the universe. It's your mission on earth" (21-22).
The above passage helps to complete the "mysterious force" thought by connecting it to the soul of the universe. The mysterious force seems negative, which can be construed as something evil to some, but it's really the person facing his or her challenge--and that can feel like fear, superstitions, negativity, doubt, or any other repressive feeling if it is translated incorrectly. The soul of the universe originates in a person's deepest desires, and when a person actually connects with the language of the universe, they feel that mysterious force. People who face this "force" or "energy" are really being challenged to pursue their full potential. Some people hide from it; some people say they will go after it later in life; some disregard it and submit to living a "safe" life; and others accept the challenge and proceed on their journey to discover their Personal Legends.
