大方廣佛華嚴經隨疏演義鈔 2.29

2.29

疏「廣則稱體而周」者，此即用大。用如體故，無不周遍。然亦二義，由體有二義故，一者能包、二者能遍。猶如虛空包含萬象遍至一切處，今用稱體之包，則一塵受世界之無邊。二稱體之遍，則剎那彌法界而無盡。上之三字，即體相用無有障礙，為所證之法界也。

In the Commentary, "'Broad' (guǎng) matches the essence and is all-pervading": this is greatness of function. Because function is like essence, there is nowhere it does not pervade. Yet it also has two meanings, because the essence has two meanings: first, being able to encompass; second, being able to pervade. Just as empty space encompasses myriad phenomena and pervades all places, now function matches the essence's encompassing, so that a single dust mote receives boundless worlds. Second, matching the essence's pervasion, a single instant extends throughout the dharmadhātu without end. The three characters above are the unimpeded essence, characteristic, and function, serving as the dharmadhātu that is realized.
