I did write, Master Yoda.
1) Is there a you, at all, anywhere, in any way, shape or form?
No. There is just body, impulses, movements acting upon impulses, thoughts following impulses. There is sounds and sights and body perception, there are feelings of like and dislike. There are habitual patterns of behavior which I call "me". There is a face in the mirror I call "me". But no substantial, real self.
2) Explain in detail what the self is and how it works.
The self is a construct. A habit, a conditioned reflex.Or a label attached to habits, movements, decisions.
Some of the body movements are labeled "self - ("I did this"). But most movements just happen without being noticed.
Although there is no one "doing perception", a perceiver is being assumed. In reality there is not perceiver and percept. This is a learned story, maybe through language. Sights and sounds are just there. There is no perceiver.
3) How does it feel to be liberated?
actually kind of ....free. Although, everything is going on like always. Just without taking the I-label for real. Anger arises, stupid automatic reactions happen. Insecurity, impatience and and everything else is taking place. But it is not such a big deal because it is not I who is stupid, insecure, impatient. I can't take it personal anymore. It doesn't really make sense to be proud of achievements, or disappointed about lack thereof. It will take some time to explore these things
It feels like I have shed a filter, a bubble I have been living in.
I could for years not stand being alone with myself. Had most of the time a sensation that I should do something else than that I was doing. Since the first Ipod arrived in this house, I was listening to podcasts or music always. I couldn't STAND the chatter in my head. This has changed. the last few days I actually enjoyed being alone, observing I-thoughts attaching themselves to other thoughts, and there was - peace, somehow.
The instinct of self preservation is intact. I don't know yet is how it is going to feel facing death, if fx. a terminal illness is diagnosed.
4) how would you describe it to somebody who has never heard about no you?
The believe in a self, a soul, a personal essence is like animistic believes (that the sun is alive, that there are gods in the trees, that a falling stone
wants to fall down). A unnecessary hypothesis.
"I" am the product of my genes and my upbringing. There is no room, no necessity, no possibility for the existence of a personal essence.
