入苦籠檻（檻胡黤反籠字正冝作櫳三蒼曰櫳所以宬禽獸闌檻也說文曰櫳牢也郭璞注山海經曰檻闌也謂穿地為坑上安櫺子以閉禽獸也今經意謂三界苦如彼櫳檻囚繫眾生或謂三途劇苦名苦櫳檻也）。

入苦籠檻 (Entering the cage and pen of suffering): 檻 (*jian*) is pronounced 胡 (*hu*) + 黤 (*yan*) [jiàn]. The character 籠 should properly be 櫳. The *Sancang* says: '櫳 (*long*) is an enclosure or pen used to hold birds and beasts.' The *Shuowen* says: '櫳 (*long*) means pen/cage.' Guo Pu's commentary on the *Shanhaijing* says: '檻 (*jian*) means railing; digging a pit in the ground and setting bars over it to confine birds and beasts.' Here the sūtra means that the suffering of the triple realm is like such a cage, imprisoning sentient beings; or it refers to the severe suffering of the three realms of woe as the "cage and pen of suffering".'
