維摩經略疏 1.75

二、明聞者，《大經》有四種：一聞聞、二不聞聞、三聞不聞、四不聞不聞。今恐此是四教辨聞，藏教即聞聞，以小生生大生故名生生，今亦得云少聞成大聞故名聞聞。

Second, explaining "heard": in the Mahāparinirvāṇa Sūtra, there are four kinds: (1) hearing what is heard, (2) hearing what is not heard, (3) not hearing what is heard, and (4) not hearing what is not heard. Now it is plausible that these distinguish hearing in terms of the four teachings. The Tripiṭaka Teaching is "hearing what is heard." Just as "rebirth and rebirth" (saṃsāra) is named so because small rebirth produces great rebirth, here too one may say that slight hearing becomes great hearing, hence it is called "hearing what is heard."
