Santiago wanted to know what a mysterious force was and so the King of Salem explained,
“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, or whatever it is that you do, when you really want something, its because that desire originated in the soul of the universe. It’s your mission on earth.”
