Fear's two causes

Fear has only two causes: the thought of losing what you have or the thought of not getting what you want. In either case, the worst thing that can ever happen is a story. Nothing you need can be taken from you. And no one can ever have anything you need. Need is a story you tell yourself. It’s a lie that causes you pain and separates you from yourself. It’s wanting what is not that separates you from what is.
