三彌勒經疏 1.13

1.13

言「我聞」者，傳法菩薩自指己身言：「如是法，親從佛聞。」故名我聞也。我謂諸蘊世俗假者，聞謂耳根發識理受，攝別就總，故說我聞。

As for stating 'have I heard' (mayā śrutam): the bodhisattva transmitting the Dharma points to his own person and says: 'Such Dharma, I personally heard from the Buddha.' Therefore it is called 'I heard'. 'I' refers to the conventional designation of the aggregates in worldly terms; 'heard' refers to the ear faculty giving rise to consciousness and rationally receiving it. Subsuming the particular into the general, one therefore says 'I heard'.
