In Hawaiian and Tahitian culture, mana is a spiritual energy and healing power which can exist in places, objects and persons. Hawaiians believe that mana may be gained or lost by actions, and Hawaiians and Tahitians believe that mana is both external and internal. Sites on the Hawaiian Islands and in French Polynesia are believed to possess mana—for example, the top rim of the Haleakalā volcano on the island of Maui and the Taputapuatea marae on the island of Raiatea in the Society Islands.
