Rebirth sucks.
I never understood that part. Maybe the next life does suck, but so what? I’m not going to be there to experience it, and the next guy won’t have any memory of me, so who cares? Reincarnation as a concept never made sense to me. You get a new body, your memories get erased… what is even left of you?
Even if I did believe in that, I still wouldn’t care. Trying to destroy your soul by reaching nirvana so that it can’t be reborn seems to me akin to trying to destroy your carbon atoms so that they can’t be recycled into other organisms’ bodies. I mean… you could, I guess, but why on earth would you care about that?
