大方廣佛華嚴經疏 6.64

6.64

第三知足天長行十法中，第一天得總相法門，諸佛將興皆生彼天，下生之時普應法界，頓闡華嚴為圓滿法。二盡虛空等者，光明色身皆遍空界，了不可取，故云清淨。三以淨願力滅惑業苦。四五可知。六普化等者，普即無偏、常即無間，示其真樂即如來藏。七自覺智境佛已入之，故示物同悟。八以淨福堅菩提心。九謂仰觀下化。十即照現迅疾也。

Among the ten dharmas in the prose of the third [group], the Tuṣita [Devas]:
The first deva attains the dharma-gate of the general mark: when all Buddhas are about to arise, they are all born in that heaven; at the time of descending to be born, they universally respond to the dharmadhātu, suddenly expounding the Avataṃsaka as the complete and perfect teaching.
Second, regarding 'exhausting empty space' and so on: the light and physical body both pervade the realms of space, and being completely ungraspable, it is called 'pure.'
Third: by the power of pure vows, destroying the suffering of afflictions and karma.
Fourth and fifth can be known.
Sixth, regarding 'universally transforming' and so on: 'universal' means without partiality; 'constant' means uninterrupted. Showing their true bliss is the tathāgatagarbha.
Seventh: the realm of self-awakened wisdom is what the Buddha has already entered; therefore, he shows beings that they may awaken together.
Eighth: using pure merit to consolidate the bodhicitta.
Ninth means looking up in contemplation and transforming those below.
Tenth is illuminating and manifesting with rapid speed.
