大乘百法明門論解 1.12

1.12

又論乃體，則取聲、名、句、文四法；大乘為用，此論體上有揀小運載二義，故云大乘。以體就用，攝用歸體，云大乘即論，持業釋也。

Furthermore, the treatise is the essence, taking the four dharmas of sounds, names, sentences, and phonemes; the Mahāyāna is the function, for upon this treatise's essence there are the two meanings of setting aside the lesser and conveying [beings], hence it is called Mahāyāna. Subordinating the essence to the function and subsuming the function into the essence, saying "the Mahāyāna that is the treatise," is a karmadhāraya compound.
