印讚所讚者，印讚須菩提之所讚也。即經云「善哉善哉」是讚也。「如汝所說」是印也。「如來善護念」等，是所讚也。

"Endorsing and praising what was praised": endorsing and praising what Subhūti praised. Namely, the sūtra saying "Excellent, excellent!" is the praise; "It is as you have said" is the endorsement; "The Tathāgata well protects and is mindful of..." and so forth is what was praised.
