Dihanin (also Dehanin or Diqanin) is the central figure of Bunun religion: the word means 'sky' or 'heaven' and at the same time names the supreme spiritual power that pervades it. The Bunun draw a threefold distinction between bunun (human beings), hanitu (the spirits inhabiting all things), and dihanin (the sky-power or deity). Dihanin is understood abstractly rather than as an anthropomorphic god; its will is read in wind, rain, thunder, lightning, the sun, the moon, and the stars, and it governs the weather, the growth of the millet on which Bunun life depended, and the fate and moral conduct of people. Because dihanin witnesses and sanctions human behaviour, it underwrote the Bunun sense of taboo and moral community. After the spread of Christianity among the Bunun from the 1940s onward, dihanin was not abandoned but reinterpreted as the Christian God, layering the older sky-power onto the new framework.
