金剛經纂要刊定記 7.12

7.12

以能下。明不失之由。謂真菩提必須具足二莊嚴故，智慧即真身，福德即應身。故論云：「法身者智相身，福相者異相身。以諸如來皆合具此二種相故。」故《法華》云：「如其所德法，定慧力莊嚴，以此度眾生，自證無上道。」

From "Because it can..." onward clarifies the reason for not being lost. That is to say, true bodhi must be fully endowed with the two adornments: wisdom is the true body, and merit is the response body. Therefore the treatise says: "The dharmakāya is the body with the mark of wisdom; that with the mark of merit is the body with distinct marks, for all Tathāgatas must be endowed with both kinds of marks." Hence the Lotus Sūtra says: "According to the Dharma they attain, / Adorned by the power of dhyāna and prajñā, / By this they deliver sentient beings / And themselves realize the unsurpassable path."
