Yes "I am never going to get it" is just a thought. There is no me that is thinking that.
When pointing to myself (body) with a finger I cant find any me. saying "I can't find any me" is wrong too cause there isnt any I that is looking for itself. Still, I dont feel like this is it.
That might be because I had 2 experiences in my life when I truly felt different. These experiences lasted for a few seconds, like 2-3, I felt there was no self and everything seemed more alive, the colors were brighter etc. I also 100% saw that everything "just happens", that there's no controller. I think Im trying to get back to these states.
Yes, trying to get back to experiences you had is probably whats holding you back. You think that that is how you should feel once you have seen no self, therefore if you dont feel that way, then you havent seen no self.
Realising that no self is true, is not about a specific experience, or mind state. Its about looking, and seeing , that there is no self in reality. Thats it. Its only a beginning, not an end.
There is no self, so there is no self to get back into the experience you had. It either happens, or it doesnt. Let go of those expectations, relax, look again at life and how it works, and really let it register that there is no you doing any of it.
