Please, do not ignore the fact that there is a sense of me which is constant over time. I think the Buddha refered to it as Asmi mana, one of the deepest rooted defilements. But please do not ignore this sense of me and do not suggest i am the only deluded person who has this sense of an unaltered and unchanging Me.
