The Aghori are known for their extreme and outlandish violations of typical Indian and other social mores, as well as their unorthodox, taboo rituals which have caused many mainstream Hindus to condemn them as non-Hindu. They are, for instance, known to engage in post-mortem ritual cannibalism, urophagia and coprophagy; they also often dwell in charnel grounds, have been witnessed smearing cremation ashes on their bodies, and have been known to use bones from human corpses for crafting skull bowls (which Shiva and other Hindu deities are often iconically depicted holding or using) and jewellery.
