問曰九眾生居云何差別。答曰。如毘曇中說。謂於前七識住上。加無想天及與非想。即是九眾生居。若言惡趣及餘第四禪。何故不立眾生居者。此如論中前釋。若彼眾生愛樂住者。立眾生居。樂住非分者。是則不立。謂彼四惡趣中多苦惱。故眾生不樂住於彼。第四禪中五淨居天。疾樂涅槃故亦不樂住。自餘第四禪如前所說。是故不立眾生居矣。

Question: How are the abodes of the nine sentient beings differentiated? Answer: As stated in the Abhidharma, to the previous seven abodes of consciousness are added the Asamjñisattva heaven and neither-perception[-nor-non-perception]; these are the abodes of the nine sentient beings. If one asks why the bad destinies and the rest of the fourth dhyāna are not established as abodes of sentient beings, this is as explained previously in the treatise: If sentient beings love and delight in abiding there, an abode of sentient beings is established; where delighting in abiding is out of the question, none is established. That is to say, in those four bad destinies there is much suffering and affliction, so sentient beings do not delight in abiding in them. The five Śuddhāvāsa heavens of the fourth dhyāna swiftly delight in nirvāṇa, so they also do not delight in abiding there. The rest of the fourth dhyāna is as stated previously. Therefore, they are not established as abodes of sentient beings.
