俱舍論頌疏論本 22.46

22.46

釋曰：修不淨觀正為治貪，貪有四種：一顯色貪、二形色貪、三妙觸貪、四供奉貪。緣青瘀等修不淨觀治顯色貪，緣虫食等治形色貪，緣虫蛆等治妙觸貪，緣屍不動治供奉貪。

The commentary says: Cultivating the contemplation of the repulsive is precisely to cure desire. There are four kinds of desire: first, desire for visible color; second, desire for shape; third, desire for fine touch; fourth, desire for adoration and service. Contemplating the repulsive by taking the blue-bruised corpse and so forth as objective support cures desire for visible color. Taking what is eaten by worms and so forth as objective support cures desire for shape. Taking worms and maggots and so forth as objective support cures desire for fine touch. Taking the motionless corpse as objective support cures desire for adoration and service.
