I don't really know. I'm open to the idea, but I'm also a bit skeptical about it as well. I know it's something that originated from buddhism, so I can sort of follow the idea, since I like some of the other ideas about spiritualism that buddhism has mentioned.
I'd Liebe to be reincarnated as a cool bird, though. Or, otherwise, someone who changes the world for the better, like solving the environmental crisis, if it doesn't get solved during my lifetime.
