仁王經疏 3.14

3.14

問曰：大眾與七眾有何別？有說：門別故說，未必有別。或可四大眾皆大乘眾。言七眾者，聲聞眾也。

Question: What is the difference between the 'great assemblies' and the 'seven assemblies'? Some say: they are spoken of because their categories are different, but there is not necessarily any difference. Alternatively, it may be that the four great assemblies are all Mahāyāna assemblies, while the 'seven assemblies' are the śrāvaka assemblies.
