佛說佛名經 2.31

2.31

At that time, the iron horse raised its legs and kicked continuously, shattering their bodies like dust; in a moment they revived again. They were then made to ride an iron donkey, and the donkey leaped about; the sinners fell to the ground, and the donkey became enraged, raising its legs and trampling them repeatedly, so that in a moment they died, and in a moment they revived again. Throughout one day and one night they suffered boundless punishment.
