Ob-Ugric cosmology pairs a sky god, Numi-Torum, with an earth goddess, Kaltash-Ekwa, as the two great powers from which order and law descend, a structure with obvious cousins across the Uralic and wider Siberian world. Numi-Torum is remembered as remote rather than constantly intervening, the source of law more than an actor in it, with the culture hero Mir-Susne-Khum named in the tradition as his son and as the figure who actually moves between the human and divine levels on his father's business. Alongside this sky-and-earth pairing sits a practice that has drawn more outside attention than any other feature of Ob-Ugric religion, the bear ceremonial.
The bear is not treated as ordinary game. When one is killed, a ceremony follows in which the animal is addressed as an honored guest rather than a corpse, asked forgiveness for its death, and sent home to the sky, from which it is understood to have consented to come in the first place; songs, mimed episodes and communal feasting accompany the rite, and its structure recurs, with local variation, among neighboring Siberian peoples who also hold the bear as a being owed particular respect. The ceremony is described here in outline only. Its details belong to the Khanty and Mansi who keep it, and the atlas records that the practice continues in some communities today rather than treating it as a closed chapter of the ethnographic record.
