Sanskrit sati (“good woman” or “chaste wife”), a Hindu custom of a wife immolating herself on the funeral pyre of her dead husband

Moths fly high

this cold delight

of a summer's night

their wings sing,

but my mind's not right;

see the showers spark high

like flaming air

sizzling on the water

blowing in her hair

and the women heap wood

on the fragrant pyre

and the moths and the flames

shoot higher and higher.
