Just as a prism refracts many colors, our hearts refract many emotions. Realize that you are not these emotions. These emotions are a state of your existence. These emotions can flow through you without consuming you. Life is much easier when your concentration is focused on merely being. To obtain the observer state an individual must look past personal interjections and opinions without passing judgements.
All judgements are relative to outside forces and experiences that do no necessarily attribute merit to the current situation. The ability to find oneself in a born again innocent state.
Sometimes I like to think of god or life as a flowing energy pattern. We control the harmony of this current through our thoughts and our emotions. Taking a deep breath and releasing all other ideas but something simple like strips of electric bands surging in and out of symmetry.
