EB joked that she wanted to see a blog post on the subject. ;-) In a comments section, i said i'd become a potatoista the day i reincarnate as a young male gym rat. Well, never say never, because the gods WILL make you eat it. Or more precisely, the Lords of Karma.
I share the belief that we keep coming back till we get it right. It isn't a random come-back-as-a-cockroach-next-time thing -- one progresses through human lives which are circumstanced in such a way as to cause us to evolve, to improve our characters, to perfect ourselves. At the end of each incarnation we go to "the Judgement Hall of Osiris" (only one of the names it's been given), and our progress is assessed. We are made to "realize" any harm we've done, then get a rest period before returning to that classroom we call life.
A hateful abusive bigot is very likely to come back as the sort of person he used to victimize, just so he'll learn how wrong that is. The gentle vegetarian gets points for "doing no harm" but the PETA hypocrite doesn't, and as for cold, heartless doctors ... they probably come back with a nasty illness that LOOKS psychosomatic. ;-)
My philosophy gives me a degree of comfort when i see the massive, unconquerable misery in the world. No doubt many people will want to tell me that they hope i'm happy in my little fairy-tale (even if what they REALLY want is to make me unhappy with their scorn and "superiority") -- but yes, it IS my "illusion" and YES i'm pleased to keep it. I have my reasons for thinking it valid, which will convince no one but myself.
So i could come back as a male next time ... but i hope i'll be evolved enough to have better things to do than waste much time in a gym. I hope i'll have more health and vitality than i've had in this one, so that i can get more GOOD accomplished.
