15.43

寶達頃前更入一身然地獄。云何名曰身然地獄？其地獄中縱廣五十由旬，鐵壁周匝猛火絕焰來燒罪人，罪人身中亦皆火然，罪人毛孔烟火俱出。

Baoda shortly afterward moved forward and entered a hell of burning bodies. Why is it named the Hell of Burning Bodies? In that hell, fifty yojanas in length and breadth, iron walls surround it on all sides, and fierce fire and soaring flames come to burn the sinners; within the sinners' bodies, fire also burns, and smoke and fire burst forth together from the sinners' pores.
