大方廣佛華嚴經隨疏演義鈔 79.111

79.111

疏「是以涅槃恐不修行」下，以《涅槃經》結成上義。執著過輕乍可言有，妄語過重不可言無。況無著而知，決須有矣。

Regarding the commentary's words, "Therefore, in the Nirvāṇa [Sūtra], fearing that one will not cultivate practice..." downward: it concludes and establishes the above meaning by means of the Nirvāṇa Sūtra. The fault of grasping is comparatively light, so for the time being one may say it exists; the fault of false speech is extremely heavy, so one must not say it does not exist. How much more so when Asanga knew it, it definitely must exist.
