Mana (n.) is 'the extraordinarily potent': primitive man doesn't analyse why another is superior — he has mana, and can lose it if someone steps on his shadow.
Mana (n.) names not the supernatural or the awe-inspiring but the efficacious — a force terrible because it is vastly powerful, not because it defeats reasonable expectation.
Mana (n.) is the primitive ancestor of our idea of psychic energy — and very likely of energy in general.
Mana (n.) is no concept for the primitive but a perceived relationship stuck to the object — the essence of participation mystique.

Mana (n.) is astonishment located in the thing: before something extraordinary it is not he who is astonished, but the thing which is astonishing.
Mana (n.) is the unintended influence of someone who has found access to his own unconscious — an unconscious prestige that lasts only until disturbed by conscious intention.
Mana (n.) is simply whatever impresses — and on the primitive level anything impressive is therefore medicine.
Mana (n.) is what the psychology of the unconscious calls libido investment or feeling-tone; by emotional intensity the most different things, rain, fire, a bull's strength and a game of dice, can be identical.
