「九有情居」者，《俱舍》頌云「應知兼有頂，及無想有情，是九有情居，餘非不樂住。」前七識住及第一有，并無相天，名九有情居。餘惡趣等，非有情居，不樂住故。廣如彼說。

Regarding the "nine abodes of sentient beings", the verse of the Kośa says: "One should know that, together with the Peak of Existence / and non-percipient sentient beings, these are the nine abodes of sentient beings; / the others are not, as they do not dwell gladly." The previous seven stations of consciousness, together with the Highest Existence and the non-percipient heaven, are called the nine abodes of sentient beings. The other bad destinies and so forth are not abodes of sentient beings, because they do not dwell gladly. It is as explained extensively there.
