The Paiwan tribe believes that their ancestral spirits, dwelling in Mountain Beidawu, descend every five years with god of genesis Dagaraws to pay a visit to their descendents. A ceremony, which is held every five years for the Paiwan to invite the deities to accept offerings in the human world, is the tribe’s most important ritual. The five-year ceremony lasts 7 to 15 days and is divided into three stages, among which, the “spearing of the bliss balls,” or djemuljat, is considered the highlight of the festival. Women and men whose wives are pregnant are not allowed to take part. Men who succeed in spearing the balls with their bamboo poles win applause from tribespeople. This particular ritual is to wish for good harvest and blessing for the tribe.
