大方廣佛華嚴經隨疏演義鈔 18.100

18.100

疏「先明廣容」者，然法界如空有二義：一廣容、二普遍。今一塵如法界之包含故，即是廣容。

Regarding the commentary's phrase "First clarifies vast accommodation": the dharmadhātu is like space in possessing two meanings: first, vast accommodation; second, universal pervasion. Here, because a single dust mote encompasses like the dharmadhātu, it is vast accommodation.
