The rituals described also share another trait: they all seem to go horrendously wrong. Grant calls this a "tangential tantrum," but I can think a stronger words to describe one's students dying or going insane. Alleged instances include a trapeze artist falling off a giant Tree of Life framework into an open well, aquarium monsters emerge to have sex with a Priestess, and an Indian temple baboon dissapears into a column of purple smoke never to be seen again. To be sure, some people derived benefits from these rites: one woman supposedly became a great dancer after she sucked off a giant Mayan squid-bat in an abandoned chapel in Wales (pp. 243-6)!
