大方廣佛華嚴經疏 28.18

28.18

十一房舍中，攝取一切諸佛所住，謂聖、天、梵等。後言不捨佛最上住者，住大寂室。餘取事類例，可以虛求。

Eleventh, in houses: subsuming the abodes of all Buddhas, namely the noble, heavenly, and brahma [abodes], and so forth. Later saying 'not relinquishing the supreme abode of the Buddhas' means abiding in the room of great quiescence. The rest is inferred by analogy with phenomenal categories, which can be sought in the immaterial.
