大般涅槃經義記 4.210

4.210

The text has six parts: First, Mañjuśrī raises Cunda's doubt and requests the Buddha to explain and resolve it. Second, the Buddha allows the doubt to be stated and promises to eliminate it. Third, Mañjuśrī poses the actual question. Fourth, the Tathāgata explains and resolves it. Fifth, Mañjuśrī comprehends it. Sixth, where it is difficult to understand, Kāśyapa holds an extensive discussion in question-and-answer with the Buddha.
