As you no doubt know, I'm a pretty rational guy. I don't go in much for the spiritual stuff. I'll buy into the notion of a soul and an afterlife just as soon as a physicist wins the Nobel Prize for proving their existence. Until then, it would be generous to call me a skeptic.
However, IF I were spiritually inclined, the idea of a reincarnation powered karmic-wheel-of-life type of model holds a certain appeal to me. Sort of fits in with the whole closed-loop, First Law of Thermodynamics model where nothing is created or lost, it just changes states.
Makes MUCH more sense than some bearded, all-powerfull Sky-Daddy tuned in to a Universal Prayer CB, 24/7, deciding whether to grant or deny someone's request for Divine Intervention on the selection of lottery ticket numbers or the outcome of a football game.
Having said that, I must point out a phenomena I've noticed among reincarnation advocates. They all seem to be "reincarnates" of famous or notable people.
An "Indian Princess".
I have yet to meet a self proclaimed "reincarnate" who claimed to have been a gas master at Auschwitz.
Instead of hearing "In a previous life I was Queen Elizabeth's handmaiden", I would like to hear someone fess up to the fact that
"In a previous life, I was an itinerate shit-shoveler who traveled by foot, with my only possession (a shit encrusted shovel) from town to town where I mucked stables for an apple and a piece of moldy bread. I died, unloved and without a friend in the world or a penny to my name, at the age of 17 from a huge infected boil on my ass. If I had a name, neither I nor anyone else remebers what it was. I barely existed at all."
That would lend a bit of credence to the idea, wouldn't it?
