1) Is there a you, at all, anywhere, in any way, shape or form?
No. There is a physical body, and a mind with a lot of conditioning. There are sensations that interplay with the thought networks of the mind. But there is no separate agent controlling or deciding anything, or to which anything is happening. Body, mind, awareness, that's all.
2) Explain in detail what the self is and how it works.
The self is interplay between the body, mind, and awareness. A sensation arises in awareness, it sets off a network of thought in the mind, and the chain reaction plays out, or thought gets caught in a feedback loop. The story of me is part of the network of thought, and while it can be treated as real, like a superstitious belief it is not based in reality -- it is a story, a belief. Try to find it, and it is not there. Test it, and it does not exist.
3) How does it feel to be liberated?
If this is liberation, it feels like a big letdown. I was expecting it to be a huge relief, and instead things feel basically the same. Awareness of how the self is fabricated seems to short-circuit the feedback loop, but it is embedded in so many ways that it is continually starting up. It is often quite subtle and escapes the attention for a while.
4) how would you describe it to somebody who has never heard about no you.
The way I have explained it is that I used to wonder why the stories of Santa Claus and the Tooth Fairy are taught to small children. It didn't make sense, because the maturing mind will eventually see through these stories. During this time, most children are being taught religion as well. Didn't it logically follow that, having been fooled before, these stories would ultimately cause children to question the story of their religion as well? It didn't make sense to me, because the cultures wanted children to believe in their religion. So why trick children with stories, and then want them to believe an even bigger story?
However, I had it all wrong. The stories of Santa Claus and the Tooth Fairy aren't about the existence of God, they are about the existence of self. It is our stories of ourselves, the me, that we should come to question. Does the me really exist? Santa seemed real. In the morning there were presents. The self seems real. I have my own name, I own a car, and everyone treats me as a separate entity with free will. There is collusion to make it seem real. It is exactly like Santa Claus and the Tooth Fairy. There is no Santa, and there is no you.
