Balinese celebrates the victory of Dharma over Adharma during this 10-day-celebration. It is believed that our ancestors are visiting us during these holy days to help us defeating the bad and evil force. This event is often linked to the mythology of Barong and Rangda. Barong symbolizes the good force and Rangda symbolizes the curse or the evil one, although in Bali both of these forces are considered holy. Barong and Rangda symbolize the balance between constructive force and destructive force (Rwa Bhineda), same concept as Yin and Yang.
