Why this discourse

SN 6.7 and SN 6.8 warned, in compact verse, against measuring the immeasurable — without saying what the named monks had actually done. This discourse returns to Kokālika directly, now gravely ill, and supplies the missing context: the independent divinity Tudu visits him at night, urging him to trust Sāriputta and Moggallāna. Kokālika's dismissive reply — questioning why a declared non-returner would even be here to say so — refuses the warning outright. What follows is delivered as consequence rather than further persuasion: the image of an axe born in every person's mouth, the gambling metaphor of a losing hand, and a hell-duration measured in numbers so vast the verse itself seems to strain under them.

Reading guide

A bedside visit, not a philosophical debate

Unlike this vagga's earlier discourses, staged as visits to distant realms or exchanges before the Buddha, this one takes place at Kokālika's own sickbed, late at night, the setting itself signaling that something more urgent than doctrine is at stake.

A warning refused before it can even be explained

Tudu's message is simple and direct — have confidence in Sāriputta and Moggallāna — but Kokālika doesn't engage with it at all; he questions Tudu's own credibility instead, pointing out that a declared non-returner has no business being here, dismissing the messenger rather than considering the message.

An axe born in every mouth: unavoidable, not exceptional

The first verse's image doesn't describe Kokālika as uniquely dangerous; it describes every person as born with the capacity to injure themselves through speech — the fool is simply the one who uses what everyone carries.

A losing hand at dice, escalated past all proportion

The verses build a deliberate contrast: losing money and even oneself at dice is called only a trivial loss, against which corrupting one's mind toward the noble ones is named the truly terrible hand — measuring slander not against ordinary misfortune but against the worst outcome the metaphor can offer.

Numbers built to overwhelm rather than inform

The closing verse's hell-duration figures — nested units of hundred-thousands and ten-millions — are not meant to be calculated precisely; their function is to communicate a scale of consequence too large for ordinary comprehension, matching the gravity of what provoked it.

Key terms

anāgāmī — “non-returner” — the attainment the Buddha declared for Tudu, which Kokālika cites skeptically to dismiss his warning.
kuṭhārī jāyate mukhe — “an axe is born in the mouth” — the first verse's image of speech's inherent danger, present in every person.
kali — a losing throw at dice, ill fortune — the recurring metaphor structuring the verses' escalating comparison.
sugatesu manaṁ padosaye — “to corrupt the mind against the fortunate ones” — named as the one truly terrible losing hand, worse than any material loss.
sataṁ sahassānaṁ nirabbudānaṁ — “a hundred thousand times a hundred million” — the opening figure of the closing verse's deliberately overwhelming hell-duration count.

The text

The discourse in full. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1At Sāvatthī. Now at that time the mendicant Kokālika was sick, suffering, gravely ill. Then, late at night, the glorious independent divinity Tudu, lighting up the entire Jeta’s Grove, went up to the mendicant Kokālika, and standing in the air he said to him, “Kokālika, have confidence in Sāriputta and Moggallāna, they’re good monks.” “Who are you, reverend?” “I am Tudu the independent divinity.” “Didn’t the Buddha declare you a non-returner? So what then are you doing back here? See how far you have strayed!”

§2“A man is born with an axe in his mouth. A fool cuts themselves with it when they say bad words.

§3When you praise someone worthy of criticism, or criticize someone worthy of praise, you choose a losing hand with your own mouth: you’ll never find happiness that way.

§4A losing hand at dice is a trivial thing, if all you lose is your money and all you own, even yourself. What’s a really terrible hand is to hate the holy ones.

§5For a hundred thousand times a hundred million, times five hundred and thirty-six times a thousand times ten million years a slanderer of noble ones goes to hell, having aimed bad words and thoughts at them.”
