There’s nothing to fear from thought itself, once we understand that it’s just thought.
Perhaps the greatest misinterpretation of this principle is to believe that the goal is to control what you think about. It isn’t. The goal is to understand thought for what it is: an ability you have that shapes your reality from the inside out. Nothing more, nothing less. What you think about is not ultimately going to determine the quality of your life, but rather the relationship you have to your own thinking — the way you manufacture your thoughts and respond to them. Do you hear your thinking as reality, or as thought?
