Let us not go this way again. One can not think out the experience of Parinibbana prior to attaining it as a person can not think out the new color that he does not know as thinking process only revolves around what we know already.
The point is that self cannot be the basis of itself so it can not be no/not-self as anatta.
One will have a glimpse or understanding/experience of what Nibbana is when one follows 8 fold Path otherwise using any conventional ideas will only bring more corruption to Dhamma and wrong views especially by those people who did not even reach Sotapanna.
