佛說佛名經 9.22

9.22

寶達頃前入燒脚地獄。云何名曰燒脚地獄？其地獄縱廣七十由旬，周匝鐵城鐵壁鐵網羅覆其中，猛火炎熾來燒罪人，或有鐵鏘銐如鋒釯來鏘罪人，地上火然間無空處。

Baoda shortly afterward entered the Foot-Burning Hell. Why is it called the Foot-Burning Hell? That hell is seventy yojanas in length and breadth, enclosed on all sides by iron walls, iron battlements, and iron nets spread over it; raging flames blaze to burn the sinners, and there are iron spikes sharp as pointed blades to thrust at the sinners; fire blazes upon the ground without any empty space.
