大般涅槃經義記 6.408

6.408

第二門中，先舉五疑，次列，後斷。聞斷第一，彼疑應故；思斷後四，彼疑真故。

Within the second gate, it first brings forth the five doubts, next lists them, and then severs them: hearing severs the first, because that doubts the responsive [body]; reflection severs the latter four, because those doubt the true [body].
