Why this discourse

Where AN 10.84 investigated a false claim to full enlightenment, Mahācunda turns to a related but distinct failure: a mendicant who boasts of meditative attainments — the four absorptions, the four formless states, and cessation itself — and is exposed by an unforgettable simile about a friend who never actually buries any treasure.

Reading guide

The teaching in one sentence

A mendicant who boasts of entering and emerging from all nine progressive meditative attainments, when grilled by a skilled investigator, turns out to be unethical, unfaithful, unlearned, hard to admonish, of bad friends, lazy, unmindful, deceptive, burdensome, and witless — a different ten qualities from AN 10.84's, but diagnosed by the identical process.

A different failure, a different diagnosis

Though this discourse reuses AN 10.84's exact investigative structure, the ten qualities uncovered are almost entirely different: rather than anger and its relatives, this diagnosis centers on basic ethical and practical failures — broken conduct, lack of faith, lack of learning, laziness — the specific profile of someone who boasts about attainments they never did the groundwork for.

The buried treasure that was never there

The discourse's central simile is one of the most vivid and specific narrative images in this project: a friend repeatedly promises buried money, sends their friend to dig in one spot after another, and each time nothing is found — until, cornered, the friend finally admits, “I had gone mad, I was out of my mind,” rather than continuing to insist the treasure exists.

A pattern of escalating, then abandoned, excuse

The simile's structure — three separate failed digs, three separate accusations of lying, and a final confession of madness rather than a fourth false promise — mirrors exactly how the discourse frames the boaster's own claims: repeated, specific, and ultimately indefensible once actually tested.

Key terms

katthī, vikatthī — “one who boasts and brags” — this discourse's own title and the failure it diagnoses.
saññāvedayitanirodha — “the cessation of perception and feeling” — the ninth and most advanced attainment among those boasted of.
khataṁ khaṇḍaṁ vilikhitaṁ kammantaṁ — “broken, tainted, spotty, and marred” — the vivid description of the boaster's actual conduct, opening the ten-item diagnosis.
ummattako ahosiṁ khittacitto — “I had gone mad, I was out of my mind” — the friend's final confession in the buried-treasure simile, abandoning the pretense rather than repeating it.
garubhāro — “burdensome” — one of the ten qualities unique to this discourse's diagnosis, not shared with AN 10.84's list.

The text

The discourse in full: the boaster investigated, the ten unabandoned qualities diagnosed, and the buried-treasure simile told twice. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

A boaster, investigated

§1“Take a mendicant who boasts and brags about their achievements: ‘I enter and emerge from the first absorption, the second absorption, the third absorption, and the fourth absorption. And I enter and emerge from the dimensions of infinite space, infinite consciousness, nothingness, and neither perception nor non-perception. And I enter and emerge from the cessation of perception and feeling.’ They’re pursued, pressed, and grilled by the Realized One, or by one of his disciples who has the absorptions, and is skilled in attainments, in the minds of others, and in encompassing another’s mind. Grilled in this way they get stuck or lose their way. They fall to ruin and disaster. The Realized One or one of his disciples encompasses their mind and investigates: ‘Why does this venerable boast and brag about their achievements, saying, “I enter and emerge from the first absorption … and the cessation of perception and feeling.”’

Ten unabandoned qualities, diagnosed

§2They understand, ‘For a long time this venerable’s deeds have been broken, tainted, spotty, and marred. Their deeds and behavior are inconsistent. This venerable is unethical, and unethical conduct means decline in the teaching and training proclaimed by the Realized One. This venerable is unfaithful, and lack of faith means decline … This venerable is unlearned and unpracticed, and lack of learning means decline … This venerable is hard to admonish, and being hard to admonish means decline … This venerable has bad friends, and bad friends mean decline … This venerable is lazy, and laziness means decline … This venerable is unmindful, and unmindfulness means decline … This venerable is deceptive, and deceitfulness means decline … This venerable is burdensome, and being burdensome means decline … This venerable is witless, and lack of wisdom means decline in the teaching and training proclaimed by the Realized One.’

The buried treasure that was never there

§3Suppose one friend was to say to another: ‘My dear, when you need money for some payment, just ask me and I’ll give it.’ Then when some payment falls due, that friend says to their friend: ‘I need some money, my dear. Give me some.’ They’d say: ‘Well then, my dear, dig here.’ So they dig there, but don’t find anything. They’d say: ‘You lied to me, my dear, you spoke hollow words when you told me to dig here.’ They’d say: ‘My dear, I didn’t lie or speak hollow words. Well then, dig here.’ So they dig there as well, but don’t find anything. They’d say: ‘You lied to me, my dear, you spoke hollow words when you said dig here.’ They’d say: ‘My dear, I didn’t lie or speak hollow words. Well then, dig here.’ So they dig there as well, but don’t find anything. They’d say: ‘You lied to me, my dear, you spoke hollow words when you said dig here.’ They’d say: ‘My dear, I didn’t lie or speak hollow words. But I had gone mad, I was out of my mind.’

The same diagnosis, restated

§4In the same way, take a mendicant who boasts and brags about their achievements: ‘I enter and emerge from the first absorption … and the cessation of perception and feeling.’ They’re pursued, pressed, and grilled by the Realized One, or by one of his disciples … Grilled in this way they get stuck or lose their way. They fall to ruin and disaster. The Realized One or one of his disciples encompasses their mind and investigates: ‘Why does this venerable boast and brag about their achievements, saying, “I enter and emerge from the first absorption … and the cessation of perception and feeling.”’ They understand, ‘For a long time this venerable’s deeds have been broken, tainted, spotty, and marred. Their deeds and behavior are inconsistent. This venerable is unethical, and unethical conduct means decline in the teaching and training proclaimed by the Realized One. This venerable is unfaithful … unlearned and unpracticed … hard to admonish … with bad friends … lazy … unmindful … deceptive … burdensome … This venerable is witless, and lack of wisdom means decline in the teaching and training proclaimed by the Realized One.’ It is quite impossible for a mendicant to achieve growth, improvement, or maturity in this teaching and training without giving up these ten qualities. It is quite possible for a mendicant to achieve growth, improvement, or maturity in this teaching and training after giving up these ten qualities.”
