Mmm. I didn't mean there is some self inside that must be perished to see that there is none -)
I said that we have a feeling that this self do exist. Like you know, you see a rope in darkness and you are sure that this is a snake.
Same here. So what you do? You turn on light and see - ah... no snake here at all. So same with nama-rupa. We have a feeling (not an intellectual understanding) that there is a self "in" this mind-body. This is just like a rope in darkness. So to see the truth, you either use jhana and vipassana to look through and examine carefully all this namarupa - or - you can reach nirodha, where all layers of what is namarupa disappear. In both cases this feeling of self will perish. Just two different methods with the same result to see the emptiness.
Imagine a basket filled with sand. And imagine that you have a feeling that there is some.. lets say.. iron ball inside this sand in the basket. So you can either carefully stir up all this sand and see for yourself that there is no iron ball inside, or you can start scooping out all this sand from the basket. When all sand will be taken out, you will also see that there is no iron ball inside. Two methods, result is the same.
