Final answer:
The concept of spiritual power shared by many Oceanic cultures is called mana, an impersonal supernatural force residing in people and objects, signifying sacredness and success.
Step-by-step explanation:
Among Oceanic cultures, the concept of spiritual power is best encapsulated by the term mana. Originally from Oceania, particularly the Maori of New Zealand, mana is an abstract, supernatural force believed to be present in both people and objects. It is an impersonal force that can confer sacredness, potency, and success. For example, natural landmarks like mountains or historic sites have a high concentration of mana, potentially making them places of great spiritual importance. Additionally, individual actions, such as acts of bravery or strength, could be seen as ways to accumulate mana for oneself.
Mana is deeply integrated into the practices and beliefs of many Oceanic cultures. It reflects the animist nature of these religions, which traditionally see spirits or supernatural powers residing in the natural world. The widespread appeal of such concepts is evidenced by their borrowed use in popular culture, such as video games and films, where mana is often depicted as a source of energy or power.
