And what's the structure of this? Well, there's some spiritual core here, but eventually you have the ritualistic side as it actually gets practiced. And you have a stratified society where you have a class that has a bit of a monopoly on the ritual, derives a lot of their power from that ritual. And then someone comes along and says, wait, this priesthood is more focused on power and on ritual than the true spiritual core, and they're not happy with the answers that that priesthood is delivering. Can you think of any other parallels to that? Well, a few come to my mind, and once again, these can all be debated, and that's the fun thing about history. I encourage you to debate all of these things.
