"In order to find the treasure, you will have to follow the omens God has prepared a path for everyone to follow" (31-32)
An omen is an event regarded as a portent of good or evil. Meeting with the old man at noon, Santiago was surprised that his friend bought all the other sheep and that his friend wanted to become a shepherd. The old man talks about the principle of favor ability and how if you play your cards right the first time, you are almost sure to win. The universe wants you to accomplish anything you set your mind to, and omens are one way of knowing just how to complete your goal. I believe that the universe guides you to be successful because the more you have experienced the more you can positively contribute to the world. You need to trust yourself and the path will be laid out in front of your very eyes.
"...When you want something, all the universe conspires in helping you achieve it." (24)
I believe that illustrates the theme of "Trust your intuition and the Universe will guide you" because it says the universe conspires in helping you to achieve any goal you have. If you really want something and pursuing this goal brings you joy than the Universe will help you if it is really what you want. If you are selfish or aren't fully committed to this goal then the Universe won't help you.
"People need not to fear the unknown if they are capable of achieving what they need and want." (79)
Fear is defined as an unpleasant emotion caused by the belief that someone or something is dangerous, likely to cause pain, or a threat. The driver of the caravan was talking about one day from his past. The earth had began to tremble and the Nile River overflowed. He and his wife were afraid of losing their children and their possessions. This was the backstory as to how he became a camel driver and how to understand the word of Allah. Allah is the god in Arabic religions. The word Allah (which was the quote above) connects to the theme of "Beware the destructive danger of fear" because if you fear the unknown, how will you be able to experience anything in life? Becoming a camel driver was this mans personal legend and the storm helped him realize it.
