It is said there is never a day in Bali without a ceremony of some kind. Balinese spiritual and religion have its root in Indian Hinduism, Buddhism, and the ancient animism belief. The theological basis of Hindu Bali comes from the Indian Philosophy, while the animism underlies most of the rituals. An important belief from Balinese Hindu is that the occurrence of natural incidents are affected by the spirits. Therefore the offerings, which are made from the harvests and crops, are offered to the spirits. During some ceremonies people are entering into trance. Trance is a culturally valuable trait in Bali. Trance behaviour has many manifestations and is an important shamanistic virtue.
