佛說觀佛三昧海經 2.19

2.19

"At that time, the three demon daughters saw upon their own backs an old mother they were carrying, with white hair, a wrinkled face, a twisted and crooked mouth, contorted hands and feet, and a dark, moist complexion like a stiffened corpse. In front of their chests, they were each clasping a dead infant, from whose six apertures flowed various purulent fluids, and within the pus were born worms resembling roundworms. Seeing this, the daughters screamed in horror and shrank backward. Lowering their heads to look at their navels, from their navels grew six dragons that spat water and fire, from their ears issued various winds, and their bodies became hard as iron. They saw that their female forms had turned into such wretched, base foulness. In their private parts were small worms, each having four heads—two facing up and two facing down—gnawing at the female bodies. From their mouths issued five poisons, and the poisons had five channels that ran upward to the heart and up to the throat. From the six sense faculties were born ninety-nine roots of channels, which flowed straight down to the heads of the worms, jointly irrigating and penetrating the worms' hearts. Because these women had committed various corrupt deeds over countless lifetimes, they had obtained such impure and wretched bodies through the conditions of their evil karma. Furthermore, there were worms like arm-bracelets, coiled together in rings and possessing multiple mouths, which produced the five poisons and gnawed at the female organs. Because these women had engaged in sexual misconduct in previous lifetimes, they obtained foul and loathsome bodies as their adornment.
