維摩經略疏垂裕記 1.197

二、「復次」下，明律論稱我聞。佛在波羅奈，最初為五人說契經藏，滅後阿難結集。佛在羅閱耆，最初為須那提說毘尼藏，滅後波離結集。佛在毘舍離獼猴池，最初為跋耆子說阿毘曇藏，滅後五百羅漢結集為《相續解脫經》，是佛自說故且名經，後廣集法相乃名為論。故知論藏不獨滅後也。若爾，三藏既俱佛說，故知論藏亦有稱我聞義。

Second, from "Furthermore" below, clarifying that the vinaya and śāstra also state "thus I heard". When the Buddha was in Vārāṇasī, he first spoke the sūtra piṭaka for the five people, which Ānanda compiled after [the Buddha's] demise. When the Buddha was in Rājagṛha, he first spoke the vinaya piṭaka for Sunītha, which Upāli compiled after his demise. When the Buddha was at the Monkey Pond in Vaiśālī, he first spoke the abhidharma piṭaka for the Vṛjiputra, which the five hundred arhats compiled after his demise as the Sūtra of Continuous Liberation. Because the Buddha himself spoke it, it was provisionally named a sūtra; later, when dharmalakṣaṇas were extensively collected, it was named a śāstra. Thus we know that the śāstra piṭaka did not originate only after his demise. If so, since the three piṭakas were all spoken by the Buddha, we know that the śāstra piṭaka also bears the meaning of "thus I heard".
