涅槃經遊意 1.256

1.256

此涅槃有三本：雙卷大千本及六卷。說者不同，有雙卷是小乘經，二是大乘。或云同座異聞故，廣略差別也。有云翻有廣略，多應爾。法顯得大本上帙，翻為六卷故也。

For this Nirvāṇa [Sūtra] there are three versions: the two-fascicle version, the grand thousand-fascicle version, and the six-fascicle version. Commentators differ: some hold that the two-fascicle version is a Hīnayāna sūtra, while the [other] two are Mahāyāna. Some say that because different listeners heard it in the same assembly, there are differences of expansion and brevity. Some say that the translations have expansion and brevity, which is mostly likely the case. This is because Faxian obtained the upper case of the large text and translated it into six fascicles.
