A Course in Miracles teaches that What you see reflects your thinking, and your thinking but reflects the choice of what you want to see.
Our brains are these perfectly built machines with an elegant system for filtering information far better than any algorithm from a computer search engine or social media platform.
Through the reticular activating system in our brain, we focus and only see what we have decided we want to see.
As the Course in Miracles says, the world you see is a reflection of your thoughts. So, if it’s not a loving world you see, and that brings you pain, consider choosing to see something better. Consider the idea that you don’t have to believe the same thoughts you’ve been believing about a broken world.
That’s what the phrase change begins with you means. Every creation begins with a thought. So to change your world, begin by changing your thoughts.
