Step-by-step explanation:
In Polynesia, the impersonal supernatural force is called mana. This concept, first identified among the Maori of New Zealand, represents an unnamed and unidentified force that can adhere to people or objects, rendering them sacred. Anthropologists have noted the concept of mana or a similar sacred energy field in various religious traditions, signifying a belief in an omnipresent and powerful force. The ability to accumulate mana, whether it's in certain locations with a strong presence of mana like mountains or ancient sites, or within oneself through certain behaviors, was traditionally seen as a way to become potent or successful in Polynesian culture.
