Lus- Mongolian SpiritSpirit"Water Spirits"

The Rules of Water

Every river, lake, and spring on the steppe had its Lus. Herders knew this the way they knew weather: not as belief but as fact. You did not spit into a stream. You did not wash blood from a knife in running water. You did not relieve yourself near a spring. Before fording a river, a traveler poured milk or cast food into the current and spoke aloud, asking permission to cross. Fishermen on Lake Khövsgöl left offerings on the shore before setting their nets and again when they hauled them in. The gifts were not charity. They were rent.

When someone drowned without explanation, the Lus had taken them. The body was not simply mourned. Shamans performed rites at the water's edge to seal the spirit's appetite, to keep it from reaching for the next person who waded in. Strange ripples on still water, an unexpected pull of current, a horse that refused to drink: these were warnings. The Lus could be serpentine, fish-shaped, or invisible altogether. What mattered was not their form but the fact that the water was not yours.

Shamans and the Serpent Spirits

Some shamans kept Lus among their helping spirits. Banzarov recorded that such shamans could call rain in drought or calm a flooding river. The relationship was particular: a shaman did not command all Lus but served one, bound to a specific river or lake the way a herder was bound to a valley. In return, the spirit lent its power over water.

When Tibetan Buddhism spread across Mongolia, the Lus did not vanish. They merged with the klu, the naga spirits of Buddhist cosmology who guarded underground treasures and controlled rainfall. Monks took over some of the offerings that shamans had once performed. The prayers changed. The milk poured into the river did not.
