仁王經疏 2.245

2.245

釋曰：自下第三讚佛三業。文別有五：一初二句總讚三業、二有一偈別讚三業、三有半偈讚說無畏、四有半偈讚能動地、五有半偈讚佛快說。就總讚中，初之一句總讚三業、後有一句顯己歸禮。言三業德無極者，如前所說，身業堅固、意業寂靜、口業能說，皆無窮盡，故言無極。由斯我今敬禮三寶。

The commentary states: From here on, third, praising the Buddha's three karmas. There are five distinct parts in the text: first, two lines generally praising the three karmas; second, one verse separately praising the three karmas; third, half a verse praising the fearlessness of his preaching; fourth, half a verse praising his ability to shake the earth; fifth, half a verse praising the Buddha's delightful preaching. In the general praise, the first line generally praises the three karmas, and the subsequent line demonstrates one's own taking of refuge and paying of homage. Regarding 'the virtues of the three karmas are boundless': as explained before, physical karma is firm, mental karma is tranquil, and vocal karma is capable of preaching—all are inexhaustible, and thus are called 'boundless.' For this reason, 'I now pay homage to the Three Jewels.'
