三彌勒經疏 1.146

1.146

第二釋名者，有三對：一能說所說對，謂佛說者為能說，彌勒下生經者為所說。二能受所受對，謂彌勒為能受，下生為所受。三所詮能詮對，謂彌勒下生為所詮，經為能詮也。都言雖有八相，而復後七相皆在人間，對天故皆言下生。廣談下生聖化之事故，名下生經，則依主釋也。

Second, regarding the explanation of the title, there are three pairs: first, the pair of the expounder and the expounded, where the Buddha's exposition is the expounder, and the Descent Sūtra of Maitreya is the expounded. Second, the pair of the recipient and the received, where Maitreya is the recipient, and descending to be born is the received. Third, the pair of the signified and the signifier, where Maitreya's descending to be born is the signified, and sūtra is the signifier. Overall, although there are eight aspects, the latter seven aspects are all in the human realm; in contrast to heaven, they are all called 'descending to be born'. Because it extensively discusses the holy transformative deeds of descending to be born, it is called the Descent Sūtra, which is a tatpuruṣa compound.
