金剛經纂要刊定記 3.118

3.118

恒沙命施下。釋成對治。經苦校量意令改革，以見大利故不求小利，既不求利身則不疲，身既不疲心則不惱，心既不惱則起精進，既起精進則能受持獲無邊福。故知經意為治此障成其住也。

From "Giving lives like the Ganges sands..." down: explains the fulfillment of the remedy. The sūtra painstakingly compares measures with the intention of causing reform; seeing great gain, one does not seek small gain. Since one does not seek gain, the body is not weary; since the body is not weary, the mind is not afflicted; since the mind is not afflicted, one gives rise to vigor; having given rise to vigor, one is then able to uphold it and obtain boundless merit. Therefore one knows that the intention of the sūtra is to remedy this hindrance and accomplish its abiding.
