佛說佛名經 2.26

2.26

Baoda then entered the hells, went up to the top of a high tower, and looked around in all four directions. He saw sinful people wailing as they entered through each of the four gates before Baoda. Entering the iron carts, iron oxen, iron donkeys, and iron horses—these four small hells formed one hell ahead. Why is it named the Hell of Iron Carts, Iron Horses, Iron Oxen, and Iron Donkeys? This hell is fifteen yojanas in length and breadth. The iron city within it is one yojana high. A fierce fire blazes brightly, burning its iron carts so that they are incandescent and flaming. Inside there are iron oxen whose bodies are likewise; their heads, horns, hair, and tails are all like sharp points, and from their hair fire burns and smoke and flames burst forth together. As for the iron horses, the hair on their bodies, their manes, and tails are as sharp as knife-blades; from their hair and tails fire burns, and smoke and flames burst forth together. The iron donkeys are also like this. In that hell there are iron caltrops, sharp as blades; iron spikes are strewn in confusion all over the ground, and the spikes burn with fire more fierce than before.
