大方廣佛華嚴經隨疏演義鈔 33.36

33.36

疏「起法必滅」下，釋下半。然躡上半起，上既心境相藉，即皆從緣生，生法必滅，一向絕故。剎那不住，故云「安得暫停」。

Regarding the commentary's "produced dharmas must perish" onward: this explains the second half of the stanza. However, it takes up the first half to proceed: since mind and object depend on each other, they are both born from conditions; produced dharmas must perish, entirely terminating. Because they do not abide for an instant, it says: "How could they pause for a moment?"
