大般涅槃經義記 3.296

3.296

第四句中，彼聞悟解尋說知性名為「見已」，怪妄有真故言「驚怪」，慶妄有真故「生奇想」。

In the fourth clause, his hearing, awakening, and understanding, and immediately knowing the nature upon the exposition, is called "having seen it"; marveling that the real exists within the false, it is therefore said that he was "astonished"; rejoicing that the real exists within the false, he therefore "conceived an idea of wonder."
