大毘盧遮那經供養次第法疏 2.19

2.19

此中行者，謂由此行能招諸佛大功德也。如世間鉤則有處所分劑，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，乃至能召大菩提果也。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。

Here, "practice" means that through this practice one can summon the great virtues of all Buddhas. Just as a worldly hook has a specific location and limit, and cannot pervade all places to perform summoning, now the Tathāgata's hook is not like that: it extends universally to everything, with nowhere it does not empower, even able to summon the fruit of great bodhi. In short, it completely fulfills all Tathāgata virtues and universally summons all sentient beings, also causing them to attain this path. Therefore the next line says "pervades all harm": "harm" means hooking and subduing what remains. Pervading and harming all those who are untamed, it causes them all to advance toward the sublime fruit in the practice of bodhi and attain fulfillment.
