金剛般若經依天親菩薩論贊略釋秦本義記卷上 1.16

1.16

經。佛言善哉善哉須菩提如汝所說如來善護念諸菩薩善付囑諸菩薩　自下第三明如來讚許也。於中有三。一讚述。二勅聽。三許說。此文初也。言善哉善哉者。讚之極也。所以重讚者。以須菩提讚問兩所契故。一契所化者心。二契能化者德。如汝所說等述也。

Sūtra: The Buddha said: 'Excellent, excellent, Subhūti! It is just as you have said: the Tathāgata well protects and is mindful of the bodhisattvas, and well entrusts and charges the bodhisattvas.' / Below, this thirdly clarifies the Tathāgata's praise and permission. In this, there are three parts: first, praise and endorsement; second, command to listen; third, permission to speak. This text is the first. 'Excellent, excellent' is the utmost praise. The reason for praising twice is that Subhūti's praise and question both accord: first, they accord with the minds of those who are transformed; second, they accord with the virtues of the one who transforms. 'It is just as you have said' and so forth is the endorsement.
