大般涅槃經義記 3.27

3.27

自下第三結前第二，「以是因緣我說種種喻真解脫」結成有喻。遶𧂐遍斫名「說種種」，「雖以無量阿僧祇下」結成無喻。下結第一，「或有因緣亦可為喻」結成有喻、「或有因緣不可喻」者結成無喻。

From here down, the third concludes the previous second: "Due to these causes and conditions, I speak of various analogies for true liberation" concludes the existence of analogy. Chopping all around the thicket is called "speaking of various [analogies]"; from "Although using immeasurable asaṃkhyeyas..." downward concludes the nonexistence of analogy. Below, concluding the first: "Or there are causes and conditions under which it can also serve as an analogy" concludes the existence of analogy; "Or there are causes and conditions under which it cannot be an analogy" concludes the nonexistence of analogy.
