仁王經疏 3.14

3.14

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.
