In Tibetan Buddhism and Bon, a torma is a sculpture made from butter and barley dough that is usually dyed. Tormas are used for a variety of purposes in rituals, and can be offerings to the gods, or consecrated as receptacles of divine power. In exorcistic rituals, evil forces are invited into the tormas, which are then brought outside of the settlement and destroyed. These tormas can be understood as ransom in exchange for victims plagued by spirits, or as a substitute for animal sacrifice. Some monasteries have traditions of making huge, beautifully decorated tormas, which are viewed by pilgrims at festivals like the Monlam Chenmo. Tormas can be figurative (images that depict the gods or other scenes), or they can be aniconic (symbolic shapes).
