金剛經纂要刊定記 5.102

5.102

正明。經意云：若人聞此能生信心，此信若生不信諸法，故云清淨。諸法既泯實相生焉，三身功德自此周備，豈不勝耶。

Directly clarifying. The intent of the sūtra is: if someone hears this and is able to produce faith, once this faith arises, they do not believe in phenomena, hence it is called "pure". Since all phenomena are eliminated, dharmatā arises, and the merits of the three bodies are from this point fully complete; is it not superior?
