佛說佛名經 26.14

26.14

「弟子等！自從無始已來至于今日，所有報障然其重者，第一唯有阿鼻地獄，如經所明，今當略說其相。此獄周匝有七重鐵城，復有七重鐵網羅覆其上，下有七重刀林無量猛火，縱廣八萬四千由旬。罪人之身遍滿其中，罪業因緣不相妨礙，上火徹下下火徹上，東西南北通徹交過，如魚在熬脂膏皆盡，此中罪苦亦復如是。

"Disciples! From beginningless time (anādikāla) down to the present day, among all our retributive hindrances, the heaviest is exclusively the Avīci Hell. As illuminated in the sūtras, we shall now briefly describe its characteristics: this hell is surrounded by seven layers of iron walls, with seven layers of iron nets covering it from above, and below are seven layers of sword forests and measureless fierce fires, eighty-four thousand yojanas in length and breadth. The bodies of the sinners completely fill it, yet due to their karmic conditions they do not obstruct one another. The fire above penetrates below, and the fire below penetrates above, intersecting and passing through from east, west, south, and north, like fish in a frying pan whose fat and grease are completely burned away; the suffering of sinners therein is also like this.
