There is no self that is permanent. All this results from 5 aggregates, then who is experiencing the non self?
There are several questions on this site which are more-or-less about this topic.
One which I found helpful was, How is it wrong to believe that a self exists, or that it doesn't?
I also liked this little summary of Right View, which includes, "A thicket of wrong views".
You have this question a bit upside down and backwards. The point is that we mistakenly associate the 'self' with the five aggregates. What we think is the 'self,' isn't. It's like walking around wearing a name-tag that says 'me,' and pointing at it whenever anyone asks who we are. If someone rips off our name-tag and runs away, do we suddenly stop being 'me'? But we are so used to pointing at the name-tag, that we lose track of the distinction between it and us.
The idea of 'no self' is a way of ripping off the name-tags. It's not a question of who is there experiencing 'non self'; it's a question of who is there experiencing all the false labels of 'self'.
The mind experiences not-self.
Questions about "who" are irrelevant, per the Phagguna Sutta .
I can't give answer this question. But I will attempt this question. We aren't going "non self " First question " who am i " I am "name" so I can live without "name" so I am not "name". Who told you aren't name?. Answer =mind saying
You can understand....
I am "identity " identity means docter, engineer, monk, Hindu,Muslim. So without identity you can live so you aren't identity.. Who told you aren't identity? Answer =mind saying.
I am physical body. In physical body many parts so we are discussed. I am hair so without hair we can live so I amnot hair.
I am leg and hand But without leg we can live so I amnot leg.
I am eye, ear , but without eye and ear we can live so I amnot eye and ear..
I am mind but without mind can live so I amnot mind for example comma .
I am "breath" but without breath we can't live.. This is my last lever. I amnot going next level.
