>>307131I think it is the first option. I've had thought about it long and hard during my acid fueled ruminations and realized you can only be what you are. You play a particular part in existence. Had you had another role - you would play it already, since there is no time. Everything happens at once, at this very moment. There are no past lives and no future lives, time itself is but an illusion.
Reincarnation as afterlife seems very dumb.
