疏「起世婆沙等說」者，《起世》即經、《婆沙》即論，皆同《俱舍》。《俱舍》云「此下過二萬，無間深廣同，上七捺落迦，八增皆十六」等是也。

Regarding the commentary's "Stated in the Qishi, the Vibhāṣā, and so on": the Qishi is a sūtra, and the Vibhāṣā is a treatise; both are identical to the Kośa. The Kośa says: "Twenty thousand [yojanas] below this, the Avīci is equal in depth and breadth; above are seven naraka hells, the eight additions each having sixteen," and so forth.
