金剛經纂要刊定記 5.240

5.240

問：「經文雖似前，問意全別。意云：若人發心則無有我，是誰降伏其心？」反覆如上所說，必無我。經意云：若人發菩提心已，當生度盡一切眾生之心，然不得起有眾生可度之念，亦不可起我能度之念。念既不起即無我，無我即名菩薩也。

Question: "Although the sūtra text resembles what came before, the intent of the question is completely different. Its intent is: 'If a person gives rise to the mind [set on bodhi], there is no self; who is it that subdues their mind?'" Reciprocating as stated above, there is definitely no self. The sūtra's intent is: if a person has already given rise to the mind of bodhi, they should give rise to the thought of completely delivering all sentient beings, yet must not give rise to the thought that there are sentient beings to be delivered, nor may they give rise to the thought that 'I am able to deliver them.' Once thoughts do not arise, there is no self; being without a self is precisely what is called a bodhisattva.
