You have the power to change your emotions and your thoughts, just like sliding up a scale. This changes your vibration and view of the world, which changes your external reality as well. This is what the Law of Polarity gives you. Everything exists on a spectrum between 2 ends (like love-hate, dark-light), and you can learn to slide on this spectrum at your command. So life becomes a real treat where you are on the high side of the scale (happiness e.g.) most of the time. Epic, right?!
