大方廣佛華嚴經疏 6.36

6.36

In the ninth approach, it means that the realm of sentient beings, the dharmadhātu, the realm of taming, and the realm of space are all boundless and inexhaustible. With the realm of skillful means, the bodhisattva's compassion and wisdom reveal the dharmadhātu, enact the realm of taming, and equal the realm of space; this is because liberation is attained from the obstacle of limitation. In the tenth, "contemplating sentient beings," and so on, means that out of compassion one pities, and out of wisdom one contemplates; contemplating defilements, knowing their afflictions and conduct, one transforms and delivers them. This attains liberation from the obstacle of lacking compassion and lacking skillful means.
