The teaching in one sentence
Overcome by three things that oppose the true teaching — corrupt wishes, bad friendship, and stopping half-way after achieving some trifling distinction — Devadatta is said to be going to hell for an eon, “irredeemable,” and the discourse uses his case as a named, cautionary example rather than telling his story.
What this discourse actually says — and doesn't
It is worth being precise about scope here, because Devadatta's name carries a great deal of narrative weight from elsewhere in the tradition — the Vinaya's account of his ambition to lead the Saṅgha himself, his effort to draw away a faction of monks into a separate schismatic order, and stories of attempts against the Buddha's life. None of that appears in this discourse. Devadatta is not shown speaking, scheming, or acting on stage at all. He is named as a case study for a general teaching about three factors that oppose the true teaching, and the verse that follows is compressed to the point of being genuinely ambiguous about what actually happened. Readers who already know the wider story will naturally supply it; readers who don't will find only fragments.
Three named causes
The prose section lists exactly three things, “overcome and overwhelmed” by which Devadatta “is going to a place of loss, to hell, there to remain for an eon, irredeemable”: “corrupt wishes,” “bad friendship,” and “stopping half-way after achieving some trifling distinction” when “there is still more to be done.” None of the three is elaborated. “Corrupt wishes” is left undefined — the text doesn't specify wishing for what. “Bad friendship” names a relationship without identifying who. “Stopping half-way after some trifling distinction” describes a shape familiar from many spiritual paths — gaining a real but minor attainment and mistaking it for the finish line — but again without saying what distinction Devadatta actually reached. The word translated “irredeemable” marks an unusually severe verdict; the canon elsewhere treats kammic results as changeable and contingent, which makes this discourse's flat, unqualified sentence — an eon in hell, without remedy — a genuinely striking outlier worth noting rather than passing over.
The verse: a fall from real renown
The verse's opening two stanzas add a detail the prose lacks: Devadatta was not always disreputable. “He once was considered astute, deemed to be evolved, his glory stood forth like a flame, the renowned Devadatta.” Whatever the “trifling distinction” mentioned in the prose was, it seems to have earned him genuine standing before his fall. The next line is the discourse's most consequential and most compressed: “Seduced by heedlessness, he attacked the Realized One. He has fallen to Avīci hell, four-doored and terrifying.” The verb “attacked” is left unspecified as to means — physical, verbal, or otherwise — and the text does not describe any specific incident.
The poison-and-ocean simile
The verse's final image is the clearest guide to how the text itself frames the “attack”: “One might think to pollute the ocean with a pot of poison, but it wouldn’t work, for the sea is terribly large. So too when someone attacks with words the Realized One—rightly comported, of peaceful mind—the words don’t take.” This simile specifically concerns an attack with words, which suggests the discourse's own working understanding of Devadatta's “attack” leans toward slander or hostile speech rather than physical violence — though the text does not rule out other readings, and a reader relying only on this discourse should be cautious about assuming more than it actually states. What is unambiguous is the point being made: an awakened mind offers no purchase for hostile intent to land on, whatever form that hostility takes, the way an ocean is too vast for a single pot of poison to taint.
The astute befriend, and the path still ends suffering
The closing lines pivot from warning to instruction: “The astute would befriend one like this, and follow them around” — that is, befriend someone of Devadatta's original description, rightly comported and peaceful, rather than someone corrupted by wishes and bad company — before closing with the Itivuttaka's frequent reassurance that “a mendicant who walks the path attains the ending of suffering.” Devadatta's case, whatever its outside narrative, functions here as a contrast: a path available and effective for anyone who stays on it, set against someone who, on this discourse's own telling, stopped partway and let three specific failings take over from there.
Key terms
The text
§1This was said by the Buddha, the Perfected One: that is what I heard.
§2“Mendicants, overcome and overwhelmed by three things that oppose the true teaching, Devadatta is going to a place of loss, to hell, there to remain for an eon, irredeemable. What three? Corrupt wishes … Bad friendship … When there is still more to be done, stopping half-way after achieving some trifling distinction. Overcome and overwhelmed by these three things that oppose the true teaching, Devadatta is going to a place of loss, to hell, there to remain for an eon, irredeemable.”
The Buddha spoke this matter. On this it is said:
§3“Let none of wicked desire
ever be reborn into this world.
And by this too you should know
the place where those of corrupt wishes go.
§4He once was considered astute,
deemed to be evolved,
his glory stood forth like a flame,
the renowned Devadatta.
§5Seduced by heedlessness,
he attacked the Realized One.
He has fallen to Avīci hell,
four-doored and terrifying.
§6When someone betrays the innocent,
who have done no wrong,
their bad deeds impact the one
with corrupt heart, lacking regard for others.
§7One might think to pollute
the ocean with a pot of poison,
but it wouldn’t work,
for the sea is terribly large.
§8So too when someone attacks
with words the Realized One—
rightly comported, of peaceful mind—
the words don’t take.
§9The astute would befriend one like this,
and follow them around.
A mendicant who walks the path
attains the ending of suffering.”
§10This too is a matter that was spoken by the Blessed One: that is what I heard.
