佛說佛名經 11.15

11.15

"Disciples! Regarding all the retributive hindrances from anādikāla until today, the heaviest is foremost none other than the Avīci Hell. As clarified in the sūtras, we shall now briefly describe its characteristics: Around this hell there are seven layers of iron walls, and there are further seven layers of iron nets covering it from above; below there are seven layers of blade forests and boundless fierce fires, extending eighty-four thousand yojanas in length and breadth. The bodies of the sinners completely fill its interior, yet due to the causes and conditions of sinful karma, they do not obstruct one another; the upper fire penetrates below and the lower fire penetrates above, running through and crossing from east, west, south, and north, like fish in a pan with their fat and oil completely melted away; the sinful suffering within it is also like this.
