Mana is a word found in Austronesian languages meaning power, effectiveness, prestige, where in most cases the power is understood to be supernatural. The exact semantics depends on the language. The concept is a major one in Polynesian cultures.It is part of contemporary Pacific Islander culture.ince mana comes from the animae, and those are the topic of religion, the most logical place for the topic is under religion. Marett postulates an earlier pre-animistic phase, a rudimentary religion or magico-religious phase, in which the mana is believed without the animae.
The linguist Robert Blust has pointed out that mana means thunder, storm, or wind in some languages, and has hypothesized that the term originally meant powerful forces of nature such as thunder and storm winds that were conceived as the expression of an unseen supernatural agency.
