What is the snake dance in the book Brave New World?

Bernard and Lenina watch a ritual dance of sacrifice to the gods Pookong and Jesus, where a young man slowly proceeds around a pile of snakes in the center of the Pueblo square. While walking, the young man receives a whipping until he falls and dies. The other Indians worship a statue of a man on a cross and an eagle. The scene is in stark contrast to the sanitized ordered world they are used to. It is wild, it is forbidden and it is everything that Bernard's world isn't. This is what makes it appealing to him.
