A stuck mind is the only death.

> A stuck mind is the only death—death by torture. The unquestioned mind, believing what it thinks, lives in dead ends—frustrated, hopeless, forever trying to find a way out, only to experience another dead end. And each time the problem is solved, another problem pops up. That’s how the unquestioned mind has to live. It’s stuck in the oldest stories, like a dinosaur still chewing on the same old grass.

–Byron Katie, A Thousand Names For Joy

Here she's offering a clear description of what happens when we don't stop to see if a thought is true. This is the questioning she talks about. It's called The Work.

For each troubling idea you ask four questions and then turn the idea around to its opposite. For example, the idea that "I'll never make it."

1. Is it true?

2. Can I absolutely know that it's true?

3. What happens, how do I react, when I believe this thought?

4. Who would I be without the thought?

★ Turn around: I'll always make it

This shifts core troubling beliefs from the root. Then the turnaround idea can become an affirmation–one that you experience as a realization because you did The Work to discover it.

It's worth it to do this process for any troubling thought with a physical journal. An app is fine but putting the thought down physically helps to drag it out of your head, whereas with a screen it's too easy to keep it locked inside.
