We are not any of the thoughts we might have about ourselves. They are just ideas that we form an image and identity around and that we attach to for a time.
We are the quiet space in which a thought can come into. We are there before any thought comes. We are there after an idea changes or has gone.
No thought is original to your essential being.
Feel your own presence. You are there whether you are thinking or not. This is learning to know the truth of who/what you are.
