Balinese Hinduism
The religious belief of "Tabuh Rah", a form of animal sacrifice of Balinese Hinduism includes a religious cockfight where a rooster is used in religious custom by allowing him to fight against another rooster in a religious and spiritual cockfight, a spiritual appeasement exercise of "Tabuh Rah". The spilling of blood is necessary as purification to appease the evil spirits, and ritual fights follow an ancient and complex ritual as set out in the sacred "lontar" manuscripts.
