起信論疏筆削記 20.42

20.42

所以中，論　何以故者，果人無量，劫數無邊。於爾所時，經爾所佛歎所不及，有何所以耶？謂法性下，釋也，謂性無邊故，功德如性亦復無邊。以修習斯論者，即是深入法性之所獲故。

In the reason, the treatise states: 'Why is this so?' The fruitional persons are immeasurable, and the number of kalpas is boundless. During such a time, through so many Buddhas, it is beyond praise; what is the reason? Below, 'because dharmatā' explains this: that is, because the nature is boundless, the merit and virtue are also boundless like the nature. This is because one who cultivates and practices this treatise attains it by deeply entering dharmatā.
