A single declarative image, followed by the standard disillusionment and freedom formula
Length
Very short — one image, one closing sequence
Northern parallel
The "burning chaff" (kukkuḷa) image is distinctive to this discourse, giving the vagga its own name
Difficulty
Approachable — a stark, self-explanatory image
Why this discourse
Opens Kukkuḷavagga ("Burning Chaff") with the single image that names the whole vagga: all five aggregates declared, without any preceding simile or explanation, to simply be burning chaff — one of the starkest, most compressed images in this entire book.
Reading guide
A declaration, not a simile spelled out
"Form, feeling, perception, choices, and consciousness are burning chaff" — unlike many of this book's images (the river, the lump of foam, the leash), this discourse offers no narrative setup or extended comparison, simply stating the aggregates ARE kukkuḷa, smoldering chaff or embers, directly and without elaboration.
Kukkuḷa specifically names the hot ash and glowing husks left after grain has been threshed and burned — something that looks spent and harmless from a distance but remains dangerously hot to the touch, an image of latent, easily-overlooked danger rather than active violence.
Why this image gives the vagga its name
As with several vaggas earlier in this book (Pupphavagga from a single lotus image, Khajjanīyavagga from a single etymology discourse), Kukkuḷavagga takes its name from this one especially memorable image among its fourteen discourses, most of which develop entirely different material.
The standard closing sequence
"Seeing this, a learned noble disciple grows disillusioned ... desire fades away ... they're freed ... they know they're freed" — Khandhavagga's most familiar closing formula, here following directly from the single burning-chaff declaration with no intervening argument or elaboration.
A stark opening for a vagga of increasingly fine-grained repetition
This discourse's own brevity and directness sets the tone for what follows: Kukkuḷavagga's remaining thirteen discourses will develop a series of closely related, increasingly compressed variations on giving up desire and greed for the impermanent, the suffering, and the not-self — a vagga built more on systematic repetition than on narrative or argument.
Key terms
kukkuḷa — burning chaff, hot ash and embers — the image giving this vagga its name
nibbindati — grows disillusioned — the first step in the standard closing formula
virajjati — desire fades away — the second step
vimuccati — is freed — the third step
vimuttasmiṁ vimuttamiti ñāṇaṁ hoti — "when they're freed, they know they're freed" — the formula's final, self-verifying step
The text
The complete discourse: the burning-chaff declaration, and the standard disillusionment and freedom formula. Translation: Bhikkhu Sujato (CC0, SuttaCentral).
§1At Sāvatthī. “Mendicants, form, feeling, perception, choices, and consciousness are burning chaff.
§2Seeing this, a learned noble disciple grows disillusioned with form, feeling, perception, choices, and consciousness. Being disillusioned, desire fades away. When desire fades away they’re freed. When they’re freed, they know they’re freed. They understand: ‘Rebirth is ended, the spiritual journey has been completed, what had to be done has been done, there is nothing further for this place.’”
