The Hau: Spirit of the Gift
No gift is free. Every one carries a debt that hunts you until you pay it back.
Grounded in the research on The Gift (essay) by Marcel Mauss
What the hau actually is
Hau is the Maori word for the spirit of the given thing. Marcel Mauss built his 1925 essay The Gift (Essai sur le don) on it: when someone gives you something, a piece of them comes with it. The object wants to return to its owner. So the gift is never inert and never free. It carries an obligation that physically pulls the receiver toward giving back. Mauss got this from the Maori scholar Tamati Ranapiri, who said the hau of a gift will pursue you and can even make you sick if you keep it.
The three obligations Mauss named
Mauss argued every gift economy runs on three hard rules, not optional manners: the obligation to GIVE (refusing to give is a declaration of war, it cuts the bond), the obligation to RECEIVE (refusing a gift insults the giver and says you fear the debt), and the obligation to REPAY (you must reciprocate, usually with interest). Break any one and you lose face, status, or the relationship. This is the engine, not the politeness layer on top of it.
