Emotion is energy. Emotion is the language of the universe. According to the law of attraction the human body is like a universal magnet that draws things to it by having strong emotion about it. Like attracts like, so it is something like tuning a radio into the frequency of a certain station so you can listen to the music you like. If you change to another frequency you will "pull in" another kind of music. Your emotions are the frequency that you have to tune in order to change to a better "channel."
Ancient and present day cultures around the world have always known that emotion is the language that creates our reality. Science can prove this fact, but it can't prove how or why. Science and spirituality must be "married" in order to fully understand and utilize the power within us. It is the power of emotion that makes things happen in our lives and in our world.
