Why this discourse, one-hundred-and-twelfth

A monk announces that he is fully awakened: “Rebirth is ended.” What should the others do — believe him, or doubt him? Neither, says the Buddha. Question him. And the discourse hands over the exact questions to ask — and the answers a genuine claim will give — so that real awakening shows itself not by the declaration but by how the one who makes it relates to the whole of experience.

Where MN 105 warned of those who declare awakening “out of overestimation,” this discourse gives the community a practical instrument to tell the true from the mistaken — without either credulous acceptance or cynical dismissal. The principle is precise: “you should neither approve nor reject that mendicant’s statement. Rather, you should question them.” A claim of liberation is neither rubber-stamped nor waved away; it is examined, on its merits, through a structured cross-examination.

The examination runs through the great analytical frameworks of the teaching — the four kinds of expression (the seen, heard, thought, known), the five aggregates, the six elements, the six sense fields, and finally the uprooting of “I-making, mine-making, and conceit” through the whole gradual path. At each, the truly liberated answer in the same voice: a mind “independent, untied, liberated, detached,” freed “through the ending… of attraction, grasping, fixation, insistence, and underlying tendency.” This is the “sixfold purification” (chabbisodhana) — the cleansing test by which a declaration of awakening is verified against the marks of genuine non-grasping. Real freedom, the discourse shows, is legible: it answers consistently, from every angle, in the language of letting go.

Reading guide

The teaching in one sentence

When a monk declares full awakening, neither accept nor dismiss it but question him — through the four kinds of expression, the five aggregates, the six elements, the six sense fields, and the whole path that uproots I-making — for a genuine claim answers from every angle in one consistent voice: a mind “independent, untied, liberated, detached,” freed by letting go of all grasping.

Neither approve nor reject — question

The discourse’s governing principle is a model of intellectual and spiritual honesty. Faced with “I am awakened,” the natural reactions are devotion (accept it) or suspicion (reject it) — and the Buddha sets both aside. “You should neither approve nor reject that mendicant’s statement. Rather, you should question them.” A claim this serious deserves neither blind trust nor reflexive doubt, but careful examination. And crucially, the examination is not of the person’s reputation or manner but of their understanding — can they speak, from each of the teaching’s frameworks, in a way that reveals genuine release?

The lines of inquiry

The questioner takes the claimant through the classic analytical schemes, one after another — the same frameworks by which the teaching takes apart the whole of experience:

The questionWhat is examined
The four expressionsthe seen, the heard, the thought, the known — the whole of what can be experienced and reported
The five aggregatesform, feeling, perception, choices, consciousness — what a person is
The six elementsearth, water, fire, air, space, consciousness — what the body-mind is made of
The six sense fieldseye and sights, ear and sounds… mind and ideas — where experience meets the world
I-making & conceithow the very sense of “I am” has been uprooted — answered by the whole path

The breadth is deliberate. A mistaken claimant might sound liberated on one topic by chance or by rote; but genuine awakening shows the same freedom consistently, however the question is angled — through perception, through the body’s elements, through the senses, through the structure of selfhood. Verification means seeing whether the release is total, not local.

The one voice of the freed

What is striking is how alike the true answers sound, topic to topic. To the four expressions, the arahant says: “Regarding what is seen, heard, thought, and known, I live without getting involved or shying away — independent, untied, liberated, detached, with mind free of boundaries.” (The very phrase that described Sāriputta’s insight in MN 111.) To the five aggregates: knowing each as “powerless, faded, and unreliable,” the mind is freed “through the ending, fading away, cessation, giving away, and letting go of attraction, grasping, mental fixation, insistence, and underlying tendency” for it. To the six elements: “I have not taken the earth element as self, nor is there a self based on it” — and so on. To the six sense fields: the mind freed through the ending of “desire and greed and relishing and craving” for each.

Freedom has one taste. However the question turns — expression, aggregate, element, sense — the genuine answer is the same movement of release: not grasping, not identifying, letting go at the root. The verification works precisely because true liberation is not a fact about one corner of experience but a single quality pervading all of it.

The final question: how was “I am” uprooted?

The last and deepest inquiry asks how the claimant has “eradicated I-making, mine-making, and the underlying tendency to conceit for this conscious body and externally for all signs.” And here the true answer is not a formula but a history — the whole gradual path retold in the first person: I was an ignorant layperson; I gained faith and went forth; I fulfilled the ethics, guarded the senses, was mindful, abandoned the five hindrances, entered the four absorptions, and turned the mind to the ending of the defilements through the Four Noble Truths — and my mind was freed. The eradication of conceit is shown not by a clever phrase but by a life actually walked to its end. One does not argue away the sense of self; one travels beyond it, and can recount the journey.

Why “purification”

The title — the sixfold cleansing or purification — frames the whole as a process of sifting the genuine from the false, washing a claim until what remains is either true awakening clearly shown or its absence clearly exposed. The procedure protects the community in both directions: it guards against honouring a mistaken claim (the danger of MN 105’s overestimator), and equally against dishonouring a true one through suspicion. And it ends generously. When the answers ring true through every framework, the questioner is to say “Good!”, applaud, and welcome the awakened one warmly: “We are fortunate, so very fortunate, to see a venerable such as yourself as one of our spiritual companions.” Rigorous examination and warm fellowship are not opposed; the testing exists precisely so that genuine attainment can be recognised and rejoiced in.

Key terms

chabbisodhana — the “sixfold purification” or cleansing: the structured examination by which a declaration of awakening is sifted, washing a claim until true freedom is clearly shown or clearly absent.
“neither approve nor reject — question” — the governing principle: a claim of liberation deserves neither blind trust nor reflexive doubt, but careful examination of the claimant’s understanding.
the four expressions — the seen, the heard, the thought, the known: the whole of what can be experienced and reported, the first framework of the inquiry.
the lines of inquiry — the four expressions, the five aggregates, the six elements, and the six sense fields: the great analytical schemes through which release is tested from every angle.
“independent, untied, liberated, detached” — the one voice of the freed: however the question turns, the genuine answer is the same movement of non-grasping. Freedom has one taste.
“powerless, faded, and unreliable” — how the arahant knows each aggregate, freeing the mind by “letting go of attraction, grasping, mental fixation, insistence, and underlying tendency” for it.
uprooting I-making, answered by a history — the deepest question (how conceit was eradicated) is answered not by a phrase but by the whole gradual path retold in the first person: a life actually walked to its end.

The text

The full discourse, abridged where the source repeats each framework item by item and spells out the gradual path (given fully in MN 27 and MN 107). The governing principle, the lines of inquiry, the freed answers, and the welcome are given closely. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

Neither approve nor reject

§1–3So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, and addressed the mendicants. “Take a mendicant who declares enlightenment: ‘I understand: rebirth is ended…’ You should neither approve nor reject that statement. Rather, question them: ‘Reverend, the Buddha has rightly explained four kinds of expression — speaking of the seen as seen, the heard as heard, the thought as thought, the known as known. How does the venerable know and see regarding these four so that your mind is freed by not grasping?’”

The four expressions

§4“For a mendicant whose defilements have ended, it is in line with the teaching to answer: ‘Regarding what is seen, heard, thought, or known, I live without getting involved or shying away — independent, untied, liberated, detached, with mind free of boundaries. That is how my mind is freed by not grasping.’”

The five aggregates, the six elements, the six sense fields

§5–10“Saying ‘Good!’, question them further on the five grasping aggregates. The true answer: ‘Knowing that form — and feeling, perception, choices, consciousness — is powerless, faded, and unreliable, my mind is freed through the letting go of all attraction, grasping, fixation, insistence, and underlying tendency for it.’ Then on the six elements — earth, water, fire, air, space, consciousness: ‘I have not taken any element as self, nor is there a self based on it; my mind is freed through letting go of grasping based on it.’ Then on the six sense fields — eye and sights, ear and sounds… mind and ideas: ‘My mind is freed through the ending of desire, greed, relishing, and craving for each.’”

How I-making was uprooted

§11–20“Saying ‘Good!’, question them: ‘How does the venerable know and see so that I-making, mine-making, and conceit are eradicated for this conscious body and all external signs?’ The true answer is the whole path retold: ‘Formerly I was an ignorant layperson. The Realized One taught me; I gained faith and went forth. I fulfilled the noble ethics, was content like a bird with only its wings, guarded my senses, was mindful and aware in every act. I frequented a secluded place, abandoned the five hindrances, and entered the first, second, third, and fourth absorptions. Then I turned the mind to the ending of defilements, truly understanding suffering, its origin, its cessation, and the path — and my mind was freed. Rebirth is ended. That is how I-making and conceit are eradicated.’”

The welcome

§21“Saying ‘Good!’, applaud and cheer that mendicant’s statement, and say to them: ‘We are fortunate, reverend, so very fortunate, to see a venerable such as yourself as one of our spiritual companions!’” That is what the Buddha said. Satisfied, the mendicants approved what the Buddha said.
