18.32

又立世阿毘曇論云。世尊說。有大地獄。名曰黑闇。各各世界外邊悉有。皆無覆蓋。此中眾生。自舉手眼不能見。雖復日月具大威神所有光明。不照彼色。諸佛出世大光遍照。因此光明互得相見。住在兩兩世界鐵輪外邊。名曰界外。是寒氷地獄。於兩山間。有十名。一名頞浮陀。乃至第十名波頭摩。彼中眾生。傍行作向上想。猶如守宮。鐵輪外邊恒作傍行。是其身量如頞多大。因冷風觸其身坼破。譬如熟瓜。如竹𥯤林。致大火燒。爆聲吒吒。如是眾生被寒風觸。骨破爆聲吒吒遠徹。因是聲故互得相知。或往來相觸故。互得相知。有諸眾生此中受生。若有眾生。於此間死多往生此。寒氷地獄在鐵輪外。若餘世界有眾生死。應生寒氷地獄。多彼世界鐵輪外生。兩界中間。其最狹處八萬由旬。在下無底。向上無覆其最廣處十六萬由旬。

Also, the *Lokasthiti-abhidharma-śāstra* says: The Bhagavat explained that there is a great hell named Darkness. It exists entirely on the outer perimeter of each world, without any covering above. Sentient beings in it cannot see their own raised hands before their eyes. Even though the sun and moon possess great majestic supernormal power, their radiance does not illuminate those forms. When Buddhas appear in the world, their great light shines everywhere, and only because of this light can they see one another. It is situated outside the iron circles of adjacent worlds, called 'outside the realms.' These are the cold ice hells. Situated between two mountains, they have ten names: the first is named Arbuda, and so on up to the tenth named Padma. Sentient beings in them crawl horizontally while imagining they are facing upward, just like geckos. Outside the iron circle, they constantly crawl horizontally. Their body size is as large as an *eda*. When the cold wind strikes their bodies, they split open, just like ripe melons. Just as when a bamboo grove is burned by a great fire and makes popping sounds of 'cha cha', so too when these sentient beings are struck by the cold wind, their cracking bones make popping sounds of 'cha cha' that resound far away. Because of this sound, they become aware of each other; or because they bump into each other in their movement, they become aware of each other. There are sentient beings who take birth in this place. If there are sentient beings who die in this [world], many are reborn here. The cold ice hells lie outside the iron circle. If sentient beings in other worlds die who should be born in the cold ice hells, they are mostly born outside the iron circle of that world. The narrowest part between two realms is eighty thousand yojanas, bottomless below and uncovered above; its widest part is one hundred and sixty thousand yojanas.
