The universe simply is. However, your subjective reality is controlled by how you feel about the universe and these feelings are controlled by your thoughts. So if this world is dark and fearful then so is your thinking, if the world is bright and joyful then so again is your thinking. Since the only true reality as far as you, that is your “self” is concerned, is this perception then you have an amazing power to change it. You are the very sun of your existence.
