大般涅槃經疏 1.29

1.29

就同聞眾又二：初眾集、次威儀。初文者，私謂：準一家意，須以五十二眾以為同聞，是故同聞冠五十二。今比丘當初，故云同聞。同聞為五，謂與、歎、類、眾、數，今文少眾，義合有之。

Concerning the audience who heard together, there are also two parts: first, the gathering of the assembly; second, their deportment. As for the first passage, I personally suggest: according to our school's intention, one must take the fifty-two assemblies as those who heard together; therefore, 'hearing together' heads the fifty-two. Here, the monks stand at the beginning, hence it says 'heard together'. 'Hearing together' comprises five items: accompanying, praise, category, assembly, and number. The present text lacks the word 'assembly', but in principle it should be there.
