Why this discourse
The direct companion to SN 22.127, completing the pair: the identical originate/vanish/both criterion, now defining knowledge with "truly understands" replacing "doesn't truly understand" — the same precise inversion pattern already seen at SN 22.113-114.
Reading guide
Completing the pair
"A learned noble disciple truly understands form, which is liable to originate ... liable to vanish ... liable to originate and vanish, as form which is liable to originate and vanish" — the exact inversion of SN 22.127's own definition, with the same compressed, elided phrasing.
Three discourses, one criterion, fully explored
Together, SN 22.126, 127, and 128 exhaust every way this vagga's opening criterion can be presented: combined in one discourse (126), then split across two with ignorance first (127) and knowledge following (128) — establishing the full range of presentation this vagga will use for its remaining criteria as well.
Why this variation matters beyond mere repetition
Reading all three discourses together demonstrates that neither the combined format nor the split format changes the underlying content — the criterion and its inversion remain identical regardless of how many discourses the material is divided across, reinforcing that content and presentation are genuinely separable in this collection's method.
Moving to a new criterion
With the originate/vanish criterion now fully explored across three discourses, Avijjāvagga turns next to SN 22.129-130, applying the gratification/drawback/escape triad — already familiar from SN 22.26-28 and SN 22.107-108 earlier in this book — to the same basic ignorance/knowledge question.

The text
The complete discourse, mirroring SN 22.127's structure exactly with knowledge replacing ignorance. Translation: Bhikkhu Sujato (CC0, SuttaCentral).
§1At one time Venerable Sāriputta and Venerable Mahākoṭṭhita were staying near Varanasi, in the deer park at Isipatana. … Mahākoṭṭhita said to Sāriputta: “Reverend Sāriputta, they speak of this thing called ‘knowledge’. What is knowledge? And how is a knowing one defined?”
§2“Reverend, it’s when a learned noble disciple truly understands form, which is liable to originate … liable to vanish … liable to originate and vanish, as form which is liable to originate and vanish. They truly understand feeling … perception … choices … consciousness, which is liable to originate … liable to vanish … liable to originate and vanish, as consciousness which is liable to originate and vanish. This is called knowledge. And this is how a knowing one is defined.”
