Why this discourse

Set at Kammāsadamma among the Kurus — the same distinctive setting as SN 12.60's exchange with Ānanda — this discourse opens with the Buddha asking whether the mendicants "probe within," and a mendicant's confident but unsatisfying answer, which Ānanda has to step in to rescue by asking the Buddha to teach the matter himself. What follows traces suffering back not through the full twelve-link chain but through a shorter, distinct sequence — old age and death traced to attachment (upadhi), attachment traced to craving, craving located precisely at whatever in the world seems nice and pleasant, starting at the six senses. A threefold analysis across past, future, and present ascetics and brahmins shows how seeing pleasant things as permanent, pleasurable, self, healthy, and safe grows craving into suffering, while seeing them as impermanent, painful, not-self, diseased, and dangerous lets craving go — illustrated by a beautiful, poisoned drink offered to someone dying of thirst, drunk recklessly by one traveler and refused, after reflection, by another.

Reading guide

An answer that doesn't satisfy, corrected by intervention

The discourse doesn't simply present a teaching; it opens with a mendicant's confident but unsatisfying attempt, which the Buddha's silence implicitly rejects, and which only Ānanda's direct request — "now is the time!" — manages to redirect toward a proper answer.

A distinct chain, not the familiar twelve links

"Probing" here traces old age and death directly to attachment (upadhi), and attachment directly to craving — a shorter, more targeted sequence than the full twelve-link chain, built for locating exactly where craving takes hold rather than for tracing every intervening condition.

Craving located precisely, not left vague

Rather than describing craving abstractly, the discourse names exactly where it arises and settles: whatever in the world seems nice and pleasant, run through each of the six senses in turn, giving craving a concrete address rather than treating it as free-floating.

Three tenses, one identical mechanism

Past, future, and present ascetics and brahmins are each run through the same sequence — seeing pleasant things as permanent, pleasurable, self, healthy, safe, and growing craving, attachment, and suffering as a result — making explicit that this isn't a historical curiosity but a mechanism operating identically at every point in time.

A drink that looks and tastes wonderful, and kills anyway

The poisoned goblet isn't disguised as poison; it has a genuinely nice color, aroma, and flavor, making the point that what destroys through craving typically presents itself as entirely appealing, and that the difference between the traveler who drinks recklessly and the one who reflects and refuses is exactly the difference this discourse is teaching.

The text

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

§1So I have heard. At one time the Buddha was staying in the land of the Kurus, near the Kuru town named Kammāsadamma. There the Buddha addressed the mendicants, “Mendicants!” “Venerable sir,” they replied. The Buddha said this: “Mendicants, do you probe within?” When he said this, one of the mendicants said to the Buddha, “Sir, I probe within.” “But mendicant, how do you probe within?” Then that mendicant answered, but the Buddha was not happy with the answer.

§2When he had spoken, Venerable Ānanda said to the Buddha, “Now is the time, Blessed One! Now is the time, Holy One! Let the Buddha speak of probing within. The mendicants will listen and remember it.” “Well then, Ānanda, listen and apply your mind well, I will speak.” “Yes, sir,” they replied. The Buddha said this:

§3“Take a mendicant who probes within: ‘The suffering that arises in the world starting with old age and death takes many and diverse forms. But what is the source of this suffering? When what exists do old age and death come to be? And when what does not exist do old age and death not come to be?’ While probing they know: ‘The suffering that arises in the world starting with old age and death takes many and diverse forms. The source of this suffering is attachment. When attachments exist old age and death come to be. And when attachments do not exist old age and death don’t come to be.’ They understand old age and death, their origin, their cessation, and the fitting practice for their cessation. And they practice in line with that path. This is called a mendicant who is practicing for the complete ending of suffering, for the cessation of old age and death.

§4They probe further within: ‘But what is the source of this attachment? When what exists does attachment come to be? And when what does not exist does attachment not come to be?’ While probing they know: ‘The source of this attachment is craving. When craving exists attachments come to be. And when craving doesn’t exist attachments don’t come to be.’ They understand attachments, their origin, their cessation, and the fitting practice for their cessation. And they practice in line with that path. This is called a mendicant who is practicing for the complete ending of suffering, for the cessation of attachments.

§5They probe further within: ‘But where does that craving arise and where does it settle?’ While probing they know: ‘That craving arises and settles on whatever in the world seems nice and pleasant. And what in the world seems nice and pleasant? The eye in the world seems nice and pleasant, and it is there that craving arises and settles. The ear … nose … tongue … body … mind in the world seems nice and pleasant, and it is there that craving arises and settles.’

§6There were ascetics and brahmins of the past who saw the things that seem nice and pleasant in the world as permanent, as pleasurable, as self, as healthy, and as safe. Their craving grew. As their craving grew, their attachments grew. As their attachments grew, their suffering grew. And as their suffering grew, they were not freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They were not freed from suffering, I say. There will be ascetics and brahmins in the future who will see the things that seem nice and pleasant in the world as permanent, as pleasurable, as self, as healthy, and as safe. Their craving will grow. As their craving grows, their attachments will grow. As their attachments grow, their suffering will grow. And as their suffering grows, they will not be freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They will not be freed from suffering, I say. There are ascetics and brahmins in the present who see the things that seem nice and pleasant in the world as permanent, as pleasurable, as self, as healthy, and as safe. Their craving grows. As their craving grows, their attachments grow. As their attachments grow, their suffering grows. And as their suffering grows, they are not freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They are not freed from suffering, I say.

§7Suppose there was a bronze goblet of beverage that had a nice color, aroma, and flavor. But it was mixed with poison. Then along comes a man struggling in the oppressive heat, weary, thirsty, and parched. They’d say to him: ‘Here, my friend, this bronze goblet of beverage has a nice color, aroma, and flavor. But it’s mixed with poison. Drink it if you like. If you drink it, the color, aroma, and flavor will be appetizing, but it will result in death or deadly pain.’ He wouldn’t put that beverage down. Hastily, without reflection, he’d drink it, resulting in death or deadly pain. In the same way, there are ascetics and brahmins of the past … future … There are ascetics and brahmins in the present who see the things that seem nice and pleasant in the world as permanent, as pleasurable, as self, as healthy, and as safe. Their craving grows. As their craving grows, their attachments grow. As their attachments grow, their suffering grows. And as their suffering grows, they are not freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They are not freed from suffering, I say.

§8There were ascetics and brahmins of the past who saw the things that seem nice and pleasant in the world as impermanent, as suffering, as not-self, as diseased, and as dangerous. They gave up craving. Giving up craving, they gave up attachments. Giving up attachments, they gave up suffering. Giving up suffering, they were freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They were freed from suffering, I say. There will be ascetics and brahmins in the future who will see the things that seem nice and pleasant in the world as impermanent, as suffering, as not-self, as diseased, and as dangerous. They will give up craving. Giving up craving … they will be freed from suffering, I say. There are ascetics and brahmins in the present who see the things that seem nice and pleasant in the world as impermanent, as suffering, as not-self, as diseased, and as dangerous. They give up craving. Giving up craving, they give up attachments. Giving up attachments, they give up suffering. Giving up suffering, they are freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They are freed from suffering, I say.

§9Suppose there was a bronze goblet of beverage that had a nice color, aroma, and flavor. But it was mixed with poison. Then along comes a man struggling in the oppressive heat, weary, thirsty, and parched. They’d say to him: ‘Here, my friend, this bronze goblet of beverage has a nice color, aroma, and flavor. But it’s mixed with poison. Drink it if you like. If you drink it, its nice color, aroma, and flavor will refresh you. But drinking it will result in death or deadly pain.’ Then that man might think: ‘I can allay my thirst with a fermented drink of beer, buttermilk, salt lassi, or salted infusion. But in any case, I shouldn’t drink that beverage, for it would be for my lasting harm and suffering.’ He’d put that beverage down. After appraisal, he wouldn’t drink it, and it wouldn’t result in death or deadly pain. In the same way, there were ascetics and brahmins of the past who saw the things that seem nice and pleasant in the world as impermanent, as suffering, as not-self, as diseased, and as dangerous. They gave up craving. Giving up craving, they gave up attachments. Giving up attachments, they gave up suffering. Giving up suffering, they were freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They were freed from suffering, I say.

§10There will be ascetics and brahmins in the future … There are ascetics and brahmins in the present who see the things that seem nice and pleasant in the world as impermanent, as suffering, as not-self, as diseased, and as dangerous. They give up craving. Giving up craving, they give up attachments. Giving up attachments, they give up suffering. Giving up suffering, they are freed from rebirth, old age, and death, from sorrow, lamentation, pain, sadness, and distress. They are freed from suffering, I say.”
