@richard mcnair,
I have found that the idea that 'I' came into existence once for all at the time of birth and will cease to exist at time of death is actually not comprehensible.
I don't claim to have lived before in the sense that the popular imagination would understand it. But I am obviously part of a process which started....well, when, exactly. And will end...well, when, exactly? A lot of what 'I am' like language, pre-dispositions, cultural attitudes, and many other characteristics, predate me. As does the matter from which this body is formed.
I think the ordinary picture of being an individual in the world is conventionally OK and true on a certain level, but it is not a final or only truth about human beings.
But I wouldn't want to force that view on anyone.
Incidentally, in the Western context, I think Stocism is highly admirable, except they are, as I understand it, materialist. But they understand the relationship between pleasure and suffering, which is profound.
