大般涅槃經義記 1.221

1.221

上來明佛心患已盡，自下第四文殊述讚。何故須然？文殊高人，言設非理，人多從受，故讚純陀令人歸信。「如是如是」，印可其言。「我於此」下迴解歸己，彰己先解，成其說是。「直欲試」下拂會上言。自己久知，專為試彼，是故云直。試汝純陀同諸菩薩所解之事，故云試汝諸菩薩事。由前純陀自言己解，己與諸大菩薩齊等，故須試之。

The preceding [text] explained that the Buddha's mental afflictions have already been exhausted; from here down, the fourth [section], Mañjuśrī gives his praise and affirmation. Why is this necessary? Mañjuśrī is a person of exalted status; even if his words were contrary to principle, many people would follow and accept them. Therefore, he praises Cunda to cause people to place their trust [in him]. "So it is, so it is" confirms his words. From "I in this..." downward, he traces the understanding back to himself, revealing that he himself had previously understood it and establishing the correctness of what [Cunda] said. From "[I] merely wished to test..." downward, he brushes away and brings together his previous words. Having known it long himself, it was solely to test the other, and therefore he says 'merely'. To test that the matters understood by you, Cunda, are identical with those of the bodhisattvas, he therefore says 'to test you regarding the matters of the bodhisattvas'. Because Cunda previously stated his own understanding and that he was equal with the great bodhisattvas, it was therefore necessary to test him.
