大方廣佛華嚴經隨疏演義鈔 24.5

24.5

疏「次偈空有雙觀」等者，空有雙觀即是前半，空無分量、有無邊際。入法門而常寂、即是後半。由前觀有入一切法門，由前觀空而恒寂滅。

Regarding the commentary's phrase “In the next verse, dual contemplation of emptiness and existence”, and so on: the dual contemplation of emptiness and existence is the first half [of the verse]—emptiness is without measure, and existence is boundless. Entering the Dharma doors while being constantly quiescent is the second half: through the previous contemplation of existence, one enters all Dharma doors; through the previous contemplation of emptiness, one is eternally quiescent.
