華嚴經探玄記 13.57

13.57

三順大悲分別者，謂諸外道求異解脫，以非想等為涅槃。菩薩觀之，但是有支，非離染縛，失於涅槃真淨之德，故生大悲，故云如是復染生縛也。

Third, regarding differentiation in accordance with great compassion: it means that the various non-Buddhists seek a divergent liberation, taking [the heaven of] neither-perception and so forth as nirvāṇa. The bodhisattva contemplates them and sees they are merely branches of existence, not free from the bondage of defilement, lacking the true purity and virtue of nirvāṇa; therefore he gives rise to great compassion, hence stating 'thus defilement again produces bondage'.
