大毘盧遮那成佛經疏 13.55

13.55

此中行者，謂由此行能招諸佛大功德海也。如世間鉤則有處所分位，不能遍一切處而作鉤召。今如來鉤則不如是，普及一切無所不加，乃至能招大菩提果。以要言之，悉滿一切如來功德，普召一切眾生亦令得此道也。故次句云遍一切害（害即是鉤取殘之也），遍害一切不調伏者，皆令於菩提之行而趣妙果、而得滿足也。

The 'action' here means that by means of this action one can summon the great sea of merit of all buddhas. A worldly hook has a specific location and division, unable to pervade all places to perform summoning. The Tathāgata's hook now is not like this: it universally extends to all with nothing it does not affect, even being able to summon the fruit of great bodhi. In brief, it completely fulfills all merits of the Tathāgata and universally summons all sentient beings, also causing them to attain this path. Therefore, the next phrase says 'destroying all everywhere' ('destroying' means hooking, seizing, and eliminating). Universally destroying all those who are untamed, it causes them all to advance toward the wondrous fruit through the practice of bodhi and attain fulfillment.
