金剛般若經贊述 2.91

2.91

無著釋云，即此之中答前三問也。謂「當生如是心」者，答初問。「滅度一切眾生已，而無有一眾生實滅度」者，此答第二問，謂度眾生時，不生自取云我能然；要須外不作有眾生相，內不起我能執，契順真理而度有情，方名修行。「若菩薩有我相等」者，答第三問，要證人、法二空之理，二障乃能除，方名降伏，若云我能，便非契會也。

Asaṅga explains: Within this, the preceding three questions are answered. That is, 'should give rise to such a mind' answers the first question. 'Yet when all sentient beings have been brought to final nirvāṇa, not a single sentient being has in reality been brought to final nirvāṇa' answers the second question, meaning that when liberating sentient beings, one does not give rise to grasping onto oneself by saying 'I am able to do so'; it is essential that externally one does not construct the mark of having sentient beings, and internally one does not give rise to the attachment of 'I am able', liberating sentient beings while according with true reality—only then is it called 'practice'. 'If a bodhisattva has the mark of a self, and so on' answers the third question: one must realize the principle of the two emptinesses of persons and dharmas so that the two obstacles can be removed—only then is it called 'subduing'; if one says 'I am able', then one does not accord and unite with it.
