A quick warning to all, for obvious reasons this question will be very explicit. But to the point, when Carl Jung was a small boy he had the following thoughts on being overwhelmed by the beauty of a cathedral ...
"The world is beautiful and the church is beautiful, and God made all this and sits above it far away in the blue sky on a golden throne and..." Here came a great hole in my thoughts, and a choking sensation. I felt numbed, and knew only: "Don't go on thinking now! Something terrible is coming, something I do not want to think [...] The most terrible sin is the sin against the Holy Ghost, which cannot be forgiven." [...] I gathered all my courage, as though I were about to leap forthwith into hell-fire, and let the thought come. I saw before me the cathedral, the blue sky. God sits on His golden throne, high above the world-and from under the throne an enormous turd falls upon the sparkling new roof, shatters it, and breaks the walls of the cathedral asunder." - Carl Jung, Memories Dreams Reflections
Jung is far from alone in observing that the scatological may go hand in hand with the sacred. In mythology, Horus tricking Set into eating his semen, or Odin shitting out the mead of poetry both leap immediately to mind.
What are examples of myths or religious stories that combine the sacred and the scatological? And, secondarily, if I wanted to read more about the connection between them from a theoretical standpoint is there an clear place to start?
To avoid being too broad, I'd like to narrowly define "scatological" as involving excreta (that is, excluding mere sex acts, sexual icons and sacred phalli, obscene language, etc.), in particular: piss, shit, semen, vomit, and sometimes blood - contaminating bodily fluids working for at least apparently profane and transgressive purposes, whether these are humorous, serious, or mystical. The grosser the better, naturally, and also the greater the contrast between sacred and profane.
