The Aghori
The documented contemporary order, traced to a named seventeenth-century founder, actually runs leprosy clinics and a children's home in Varanasi today — a real, ongoing service organisation with a named lineage, quite unlike its sensationalised media depiction.
Ron Barrett, Aghor Medicine (2008)
A Hindu ascetic order associated with cremation-ground practices, often sensationalised in television and travel writing as engaging in cannibalism.
