The Mandaeans are the last surviving Gnostic religion on earth, and their cosmology is bleakly awesome. According to the Ginza Rabba, our material universe was accidentally created by a monstrous entity named Ptahil, and the planets are literal demons trying to trap human souls in flesh suits. To combat this cosmic quarantine, Mandaeans perform weekly, repetitive full-body submersions in flowing rivers, which they believe acts as a direct physical portal to the Great Life.
