So does an "I" exist outside thought?
Is the sense of self just a series of "I" thoughts creating a narrative?
No, 'I' does not exist outside of thought. It is really just a series of thoughts creating a story.
But this narrative is so strong and so well created that even though I realize that it's only thoughts, I still only see it in a few moments rather than a continuum. Is it just a matter of practicing and trying to notice it all the time?
Yes, well created indeed!
Yes, please do what you suggested. Notice thought as clearly as you can. Notice how "I" thoughts come after expeience and claim or judge or do whatever they do in order to maintain the story of Kan.
Let me know in a few days how it is going.
Have a lovely weekend,
