The teaching in one sentence
Everything that makes up experience — the six senses, their objects, the six kinds of consciousness that arise from them, and the feelings that follow — is impermanent through and through, all the way down, with no permanent remainder hiding anywhere in the chain; and this is demonstrated to five hundred nuns not by assertion but by careful, repeated questioning until they see it for themselves.
A reluctant teacher
Mahāpajāpati Gotamī, the Buddha’s foster mother and the leader of the nuns’ order, asks the Buddha to have the nuns instructed. The senior monks are taking turns at this duty, and it happens to be Nandaka’s turn — but he doesn’t want to go. This small, human detail is unusual for the canon, which rarely shows a teacher's reluctance so plainly. The Buddha doesn’t let it drop: he asks Ānanda whose turn it is, learns that Nandaka is avoiding it, and directly instructs Nandaka to go and teach. Nandaka agrees, and after his alms round arrives at the Royal Monastery where the nuns have prepared a seat and washing water for him — the customary courtesies extended to a respected teacher.
A catechism, not a lecture
Before he says anything substantive, Nandaka sets the format: “Sisters, this talk shall be in the form of questions. When you understand, say so. When you don’t understand, say so. If anyone has a doubt or uncertainty, ask me about it.” The nuns respond warmly to being invited this way. What follows is not a monologue but a structured interrogation, repeated across three domains in turn: the six interior sense fields (eye, ear, nose, tongue, body, mind), the six exterior sense fields (sights, sounds, smells, tastes, touches, ideas), and the six kinds of consciousness that arise from their meeting. For each, the same three questions recur — is it permanent or impermanent? if impermanent, is it suffering or happiness? if impermanent and suffering, is it fit to be regarded as “mine,” as “I,” as “my self”? — and each time the nuns answer correctly and are praised: “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.”
Three similes, one target
Having established that the six senses and their objects are impermanent, Nandaka anticipates a specific wrong move: conceding that the sense fields are impermanent while quietly assuming the feeling they produce is somehow more stable. He closes that escape route with two similes. An oil lamp’s light depends on oil and wick that are visibly burning away — no one would claim the flame is permanent while its fuel is not. A shade tree’s shadow depends on roots, trunk, and branches that are themselves impermanent — no one would claim the shadow outlasts the tree. In the same way, the feeling that arises from contact with any sense field cannot be more permanent than the conditions it depends on; when the condition ceases, so does the feeling that depended on it.
A third simile then targets something subtler still: the assumption that the interior senses (the “flesh”) and exterior sense objects (the “hide”) remain somehow joined, bound together as if by nature. Nandaka describes a butcher expertly separating a cow’s hide from its flesh by cutting through the connecting tendons and ligaments — after which, no matter how carefully the hide is wrapped back around the carcass, hide and flesh are no longer joined. He then decodes his own simile: the flesh is the six interior fields, the hide the six exterior fields, the connecting tissue is greed and relishing, and the sharp cleaver is noble wisdom — which cuts through exactly that binding tissue, separating what habit had fused together.
The seven factors, and two visits
Nandaka closes with the seven factors of awakening — mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity — describing them as what a mendicant develops to realize “the undefiled freedom of heart and freedom by wisdom in this very life.” The nuns leave satisfied, and report to the Buddha as courtesy requires. But the Buddha, addressing the monks after the nuns have gone, offers a striking, unflattering-sounding assessment: like the moon on the fourteenth day of the lunar month — visibly not yet full — the nuns were genuinely uplifted, but “still haven’t got all they wished for.” He instructs Nandaka to give the identical teaching again the next day. When Nandaka does, and the same exchange unfolds a second time, the Buddha’s verdict changes completely: like the moon on the fifteenth day, now full, the nuns have gotten everything they wished for — “even the last of these five hundred nuns is a stream-enterer, not liable to be reborn in the underworld, assured, destined for awakening.” The discourse never states in so many words that Nandaka taught as well as the Buddha himself could have; it does something more concrete, letting the result — the full assembly, without a single exception, secured in the path — make that case on its own.
Key terms
The text
A request, and a reluctant teacher
§1–2So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. Then Mahāpajāpati Gotamī together with around five hundred nuns approached the Buddha, bowed, stood to one side, and said to him, “Sir, may the Buddha please advise and instruct the nuns. Please give the nuns a Dhamma talk.”
§3–4Now at that time the senior monks were taking turns to advise the nuns. But Venerable Nandaka didn’t want to take his turn. Then the Buddha said to Venerable Ānanda, “Ānanda, whose turn is it to advise the nuns today?” “It’s Nandaka’s turn, sir, but he doesn’t want to do it.” Then the Buddha said to Nandaka, “Nandaka, please advise and instruct the nuns. Please, brahmin, give the nuns a Dhamma talk.” “Yes, sir,” replied Nandaka. Then, in the morning, he robed up and, taking his bowl and robe, entered Sāvatthī for alms. He wandered for alms in Sāvatthī. After the meal, on his return from almsround, he went to the Royal Monastery with a companion.
The format of the talk
§4–5Those nuns saw him coming off in the distance, so they spread out a seat and placed water for washing the feet. Nandaka sat down on the seat spread out, and washed his feet. Those nuns bowed, and sat down to one side. Nandaka said to them, “Sisters, this talk shall be in the form of questions. When you understand, say so. When you don’t understand, say so. If anyone has a doubt or uncertainty, ask me about it: ‘Why, sir, does it say this? What does that mean?’” “We’re already delighted and satisfied with Master Nandaka, since he invites us like this.”
The six interior sense fields
§6“What do you think, sisters? Is the eye permanent or impermanent?” “Impermanent, sir.” “But if it’s impermanent, is it suffering or happiness?” “Suffering, sir.” “But if it’s impermanent, suffering, and perishable, is it fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir.” “What do you think, sisters? Is the ear … nose … tongue … body … mind permanent or impermanent?” “Impermanent, sir.” “But if it’s impermanent, is it suffering or happiness?” “Suffering, sir.” “But if it’s impermanent, suffering, and perishable, is it fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir. Why is that? Because we have already truly seen this with right wisdom: ‘So these six interior sense fields are impermanent.’” “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.
The six exterior sense fields
§7What do you think, sisters? Are sights permanent or impermanent?” “Impermanent, sir.” “But if they’re impermanent, are they suffering or happiness?” “Suffering, sir.” “But if they’re impermanent, suffering, and perishable, are they fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir.” “What do you think, sisters? Are sounds … smells … tastes … touches … ideas permanent or impermanent?” “Impermanent, sir.” “But if they’re impermanent, are they suffering or happiness?” “Suffering, sir.” “But if they’re impermanent, suffering, and perishable, are they fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir. Why is that? Because we have already truly seen this with right wisdom: ‘So these six exterior sense fields are impermanent.’” “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.
The six kinds of consciousness
§8What do you think, sisters? Is eye consciousness … ear consciousness … nose consciousness … tongue consciousness … body consciousness … mind consciousness permanent or impermanent?” “Impermanent, sir.” “But if it’s impermanent, is it suffering or happiness?” “Suffering, sir.” “But if it’s impermanent, suffering, and perishable, is it fit to be regarded thus: ‘This is mine, I am this, this is my self’?” “No, sir. Why is that? Because we have already truly seen this with right wisdom: ‘So these six classes of consciousness are impermanent.’” “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.
The oil lamp
§9Suppose there was an oil lamp burning. The oil, wick, flame, and light were all impermanent and perishable. Now, suppose someone was to say: ‘While this oil lamp is burning, the oil, the wick, and the flame are all impermanent and perishable. But the light is permanent, lasting, eternal, and imperishable.’ Would they be speaking rightly?” “No, sir. Why is that? Because that oil lamp’s oil, wick, and flame are all impermanent and perishable, let alone the light.” “In the same way, suppose someone was to say: ‘These six interior sense fields are impermanent. But the feeling—whether pleasant, painful, or neutral—that I experience due to these six interior sense fields is permanent, lasting, eternal, and imperishable.’ Would they be speaking rightly?” “No, sir. Why is that? Because each kind of feeling arises dependent on the corresponding condition. When the corresponding condition ceases, the appropriate feeling ceases.” “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.
The shade tree
§10Suppose there was a large tree standing with heartwood. The roots, trunk, branches and leaves, and shadow were all impermanent and perishable. Now, suppose someone was to say: ‘There’s a large tree standing with heartwood. The roots, trunk, and branches and leaves are all impermanent and perishable. But the shadow is permanent, lasting, eternal, and imperishable.’ Would they be speaking rightly?” “No, sir. Why is that? Because that large tree’s roots, trunk, and branches and leaves are all impermanent and perishable, let alone the shadow.” “In the same way, suppose someone was to say: ‘These six exterior sense fields are impermanent. But the feeling—whether pleasant, painful, or neutral—that I experience due to these six exterior sense fields is permanent, lasting, eternal, and imperishable.’ Would they be speaking rightly?” “No, sir. Why is that? Because each kind of feeling arises dependent on the corresponding condition. When the corresponding condition ceases, the appropriate feeling ceases.” “Good, good, sisters! That’s how it is for a noble disciple who truly sees with right wisdom.
The butchered cow
§11–12Suppose a deft butcher or their apprentice was to kill a cow and carve it with a sharp meat cleaver. Without damaging the flesh inside or the hide outside, they’d cut, carve, sever, and slice through the connecting tendons, sinews, and ligaments with a sharp meat cleaver, and then peel off the outer hide. Then they’d wrap that cow up in that very same hide and say: ‘This cow is joined to its hide just like before.’ Would they be speaking rightly?” “No, sir. Why is that? Because even if they wrap that cow up in that very same hide and say: ‘This cow is joined to its hide just like before,’ still that cow is not joined to that hide.” “I’ve made up this simile to make a point. And this is the point. ‘The inner flesh’ is a term for the six interior sense fields. ‘The outer hide’ is a term for the six exterior sense fields. ‘The connecting tendons, sinews, and ligaments’ is a term for greed and relishing. ‘A sharp meat cleaver’ is a term for noble wisdom. And it is that noble wisdom which cuts, carves, severs, and slices the connecting corruption, fetter, and bond.
The seven awakening factors
§13Sisters, by developing and cultivating these seven awakening factors, a mendicant realizes the undefiled freedom of heart and freedom by wisdom in this very life. And they live having realized it with their own insight due to the ending of defilements. What seven? It’s when a mendicant develops the awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity, which rely on seclusion, fading away, and cessation, and ripen as letting go. It is by developing and cultivating these seven awakening factors that a mendicant realizes the undefiled freedom of heart and freedom by wisdom in this very life. And they live having realized it with their own insight due to the ending of defilements.”
The moon not yet full
§14–15Then after giving this advice to the nuns, Nandaka sent them off, saying, “Go, sisters, it is time.” And then those nuns approved and agreed with what Nandaka had said. They rose from their seat, bowed, and respectfully circled him, keeping him on their right. Then they went up to the Buddha, bowed, and stood to one side. The Buddha said to them, “Go, nuns, it is time.” Then those nuns bowed to the Buddha respectfully circled him, keeping him on their right, before leaving.
Soon after those nuns had left, the Buddha addressed the mendicants: “Suppose, mendicants, it was the sabbath of the fourteenth day. You wouldn’t get lots of people wondering whether the moon is full or not, since it is obviously not full. In the same way, those nuns were uplifted by Nandaka’s Dhamma teaching, but they still haven’t got all they wished for.”
The same teaching, again
§16Then the Buddha said to Nandaka, “Well then, Nandaka, tomorrow you should give those nuns the same advice again.” “Yes, sir,” Nandaka replied. And the next day he went to those nuns, and all unfolded just like the previous day.
The moon full
§27Soon after those nuns had left, the Buddha addressed the mendicants: “Suppose, mendicants, it was the sabbath of the fifteenth day. You wouldn’t get lots of people wondering whether the moon is full or not, since it is obviously full. In the same way, those nuns were uplifted by Nandaka’s Dhamma teaching, and they got all they wished for. Even the last of these five hundred nuns is a stream-enterer, not liable to be reborn in the underworld, assured, destined for awakening.” That is what the Buddha said. Satisfied, the mendicants approved what the Buddha said.
