Why this discourse, one-hundred-and-thirty-seventh

This is one of the Majjhima Nikāya’s most purely architectural discourses — a map of experience built from the six senses outward, with no narrative frame, no questioner, no crisis to resolve. It is worth the effort of reading closely because the map is more interesting than it first looks: it distinguishes ordinary happiness, sadness, and equanimity from renunciate versions of each, defines a precise ladder for climbing from one to the next, and then does something unexpected — it insists that even the most refined meditative equanimity is still a rung to climb past, not a place to stop. Few discourses state so plainly that letting go does not end with achieving the best possible state; it ends with letting go of that too.

Reading guide

The teaching in one sentence

Every moment of experience runs through six sense doors, and for each door the mind can be pulled by ordinary, worldly happiness, sadness, or equanimity, or by a deeper “renunciate” version of each — and there is a precise order for climbing from the worldly kind toward the renunciate kind, then from happiness toward equanimity, and finally beyond even the subtlest meditative equanimity itself.

The summary recital

The Buddha opens by announcing the topic — “the analysis of the six sense fields” — and then gives a single, dense “summary recital” (uddesa) that names nine things that should be understood: the six interior sense fields, the six exterior sense fields, the six classes of consciousness, the six classes of contact, the eighteen mental preoccupations, the thirty-six positions of sentient beings, the principle “relying on this, give up that,” the Teacher’s threefold equanimity, and the image of the supreme trainer. Having recited the whole list, he then works through it clause by clause, each time repeating the clause, asking “why did I say it?”, and answering in full — a teaching method built for memorization first and comprehension second.

Six of everything

The base layer is pure enumeration, and it is worth having in view before the more interesting material builds on top of it:

CategoryThe six
Interior sense fieldseye, ear, nose, tongue, body, mind
Exterior sense fieldssights, sounds, smells, tastes, touches, ideas
Classes of consciousnesseye-, ear-, nose-, tongue-, body-, and mind-consciousness
Classes of contactcontact through eye, ear, nose, tongue, body, mind

From there the discourse adds the eighteen mental preoccupations: for each of the six sense doors, meeting an object can become the basis for happiness, for sadness, or for equanimity — six doors times three responses is eighteen. This is the hinge the rest of the discourse turns on.

Domestic and renunciate happiness

The discourse now distinguishes, for happiness, sadness, and equanimity in turn, an ordinary “domestic” version from a “renunciate” one. Domestic happiness is simple and familiar: joy at gaining a pleasing sight, sound, smell, taste, touch, or idea, or at recollecting one you once had. Renunciate happiness is different in kind, not just in object: it arises specifically from clearly seeing the impermanence of those very same sense objects — understanding, through direct insight, that everything met at any sense door is “impermanent, suffering, and perishable.” The joy here is the joy of insight itself, not of acquisition.

Domestic and renunciate sadness

The treatment of sadness contains the discourse’s most surprising move. Domestic sadness is exactly what it sounds like — grief at losing something pleasing, or at recalling a loss. But “renunciate sadness” is not an oxymoron here: it is the sadness of spiritual longing, arising precisely because one has understood impermanence and, seeing it, yearns for the “supreme liberations” not yet attained — “Oh, when will I enter and remain in the same dimension that the noble ones enter and remain in today?” This is a wholesome discontent: the ache of not yet being free, which the discourse treats as a legitimate and even necessary stage, not a flaw to eliminate immediately.

Domestic and renunciate equanimity

Equanimity gets the same treatment, and here the contrast is sharpest. Domestic equanimity is what “the unlearned ordinary person—a foolish ordinary person” feels at any of the six sense doors: a flat non-reaction that “does not transcend” its object, arising from never having examined limitations or the results of deeds. Renunciate equanimity looks similar from the outside — calm, unmoved — but is built on having genuinely seen impermanence, and so it does “transcend” its object rather than merely ignoring it. The discourse is careful to distinguish indifference born of not looking from equanimity born of having looked all the way through.

Relying on this, give up that: the ladder

With all three pairs defined, the Buddha states a precise sequence for practice, each step relying on a more refined state to release a coarser one: rely on renunciate happiness to give up domestic happiness; rely on renunciate sadness to give up domestic sadness; rely on renunciate equanimity to give up domestic equanimity; then rely on renunciate happiness to give up renunciate sadness; and finally rely on renunciate equanimity to give up renunciate happiness. The ladder’s top rung, notably, is equanimity — not happiness, and certainly not the wholesome sadness of spiritual longing, both of which are themselves eventually left behind.

Equanimity based on diversity, equanimity based on unity

Just when equanimity looks like the destination, the discourse subdivides it once more. “Equanimity based on diversity” is equanimity toward the five physical senses — sights, sounds, smells, tastes, touches. “Equanimity based on unity” is the equanimity of the four formless meditative attainments: the dimensions of infinite space, infinite consciousness, nothingness, and neither-perception-nor-non-perception. The instruction is to rely on unified equanimity to give up diversified equanimity — and then, remarkably, to rely on not being determined by that to give up equanimity based on unity as well. Even the most refined formless attainment is not the finish line; the finish line is not being fixed on any state at all, however exalted.

The Teacher’s equanimity

The discourse then turns, briefly, to the Buddha himself, describing three cases in which he teaches Dhamma out of kindness and sympathy: when disciples refuse to listen, he feels no unhappiness; when some listen and some don’t, he is neither unhappy nor happy but genuinely equanimous; when all listen well, he does feel happiness, without this disturbing his composure. In each case he “remains unfestering, mindful and aware.” This is not abstract doctrine — it is the renunciate equanimity just described, embodied in the person delivering the teaching, whose own peace never depends on how the teaching lands.

Eight directions of training

The discourse closes with a simile: an elephant, horse, or ox in training, however skilled, can only be driven in one direction at a time — north, south, east, or west. A person trained by the Buddha, by contrast, can be guided in eight directions: perceiving form while having form; not perceiving form internally but seeing it externally; being focused only on beauty; and then the four formless attainments in sequence, culminating in the cessation of perception and feeling. The same sequence of eight appears elsewhere in the canon under the heading of the “eight liberations” — here it functions as a portrait of a training so complete and so flexible that it is not limited to any single track, unlike an animal driven only ever the one way its trainer has taught it.

Key terms

uddesa & vibhaṅga — “summary recital” and “analysis”: the compressed nine-part list given whole at the start, then unpacked clause by clause across the rest of the discourse.
gehasita / nekkhammasita — “domestic” (worldly, household-based) versus “renunciate” (based on letting go): the discourse’s core distinction, applied in turn to happiness, sadness, and equanimity.
renunciate sadness — the discourse’s most distinctive category: a wholesome longing for liberation not yet attained, treated as a necessary stage rather than a fault.
diversified / unified equanimity — equanimity toward the five physical senses versus the equanimity of the four formless attainments; the discourse insists on releasing even the latter.
the eight directions — the closing simile’s list, matching the “eight liberations” found elsewhere in the canon, contrasted with an animal trainable in only one direction.

The text

The discourse in full: the summary recital, and its complete clause-by-clause analysis — the six sense fields, the eighteen preoccupations, the thirty-six positions, the give-up ladder, the two kinds of equanimity, the Teacher’s threefold composure, and the closing simile of the eight directions. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

The summary recital

§1–2So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. There the Buddha addressed the mendicants, “Mendicants!” “Venerable sir,” they replied. The Buddha said this:

“Mendicants, I shall teach you the analysis of the six sense fields. Listen and apply your mind well, I will speak.” “Yes, sir,” they replied. The Buddha said this:

§3“‘The six interior sense fields should be understood. The six exterior sense fields should be understood. The six classes of consciousness should be understood. The six classes of contact should be understood. The eighteen mental preoccupations should be understood. The thirty-six positions of sentient beings should be understood. Therein, relying on this, give up that. The Noble One cultivates the establishment of mindfulness in three cases, by virtue of which they are a Teacher worthy to instruct a group. Of all meditation tutors, it is he that is called the supreme guide for those fit for training.’ This is the summary recital for the analysis of the six sense fields.

The basic enumeration

§4–9‘The six interior sense fields should be understood.’ That’s what I said, but why did I say it? There are the sense fields of the eye, ear, nose, tongue, body, and mind. ‘The six interior sense fields should be understood.’ That’s what I said, and this is why I said it.

‘The six exterior sense fields should be understood.’ That’s what I said, but why did I say it? There are the sense fields of sights, sounds, smells, tastes, touches, and ideas. ‘The six exterior sense fields should be understood.’ That’s what I said, and this is why I said it.

‘The six classes of consciousness should be understood.’ That’s what I said, but why did I say it? There are eye, ear, nose, tongue, body, and mind consciousness. ‘The six classes of consciousness should be understood.’ That’s what I said, and this is why I said it.

‘The six classes of contact should be understood.’ That’s what I said, but why did I say it? There is contact through the eye, ear, nose, tongue, body, and mind. ‘The six classes of contact should be understood.’ That’s what I said, and this is why I said it.

‘The eighteen mental preoccupations should be understood.’ That’s what I said, but why did I say it? Seeing a sight with the eye, one is preoccupied with a sight that’s a basis for happiness or sadness or equanimity. Hearing a sound with the ear … Smelling an odor with the nose … Tasting a flavor with the tongue … Encountering a touch with the body … Becoming conscious of an idea with the mind, one is preoccupied with an idea that’s a basis for happiness or sadness or equanimity. So there are six preoccupations with happiness, six preoccupations with sadness, and six preoccupations with equanimity. ‘The eighteen mental preoccupations should be understood.’ That’s what I said, and this is why I said it.

‘The thirty-six positions of sentient beings should be understood.’ That’s what I said, but why did I say it? There are six kinds of domestic happiness and six kinds of renunciate happiness. There are six kinds of domestic sadness and six kinds of renunciate sadness. There are six kinds of domestic equanimity and six kinds of renunciate equanimity.

Domestic and renunciate happiness

§10–11And in this context what are the six kinds of domestic happiness? There are sights known by the eye, which are likable, desirable, agreeable, pleasing, connected with the worldly pleasures of the flesh. Happiness arises when you regard it as a gain to obtain such sights, or when you recollect sights you formerly obtained that have passed, ceased, and perished. Such happiness is called domestic happiness. There are sounds known by the ear … Smells known by the nose … Tastes known by the tongue … Touches known by the body … Ideas known by the mind, which are likable, desirable, agreeable, pleasing, connected with the worldly pleasures of the flesh. Happiness arises when you regard it as a gain to obtain such ideas, or when you recollect ideas you formerly obtained that have passed, ceased, and perished. Such happiness is called domestic happiness. These are the six kinds of domestic happiness.

And in this context what are the six kinds of renunciate happiness? When you’ve understood the impermanence of sights—their perishing, fading away, and cessation—happiness arises as you truly understand through right understanding that both formerly and now all those sights are impermanent, suffering, and perishable. Such happiness is called renunciate happiness. When you’ve understood the impermanence of sounds … smells … tastes … touches … ideas—their perishing, fading away, and cessation—happiness arises as you truly understand through right understanding that both formerly and now all those ideas are impermanent, suffering, and perishable. Such happiness is called renunciate happiness. These are the six kinds of renunciate happiness.

Domestic and renunciate sadness

§12–13And in this context what are the six kinds of domestic sadness? There are sights known by the eye, which are likable, desirable, agreeable, pleasing, connected with the worldly pleasures of the flesh. Sadness arises when you regard it as a loss to lose such sights, or when you recollect sights you formerly lost that have passed, ceased, and perished. Such sadness is called domestic sadness. There are sounds known by the ear … There are smells known by the nose … There are tastes known by the tongue … There are touches known by the body … There are ideas known by the mind, which are likable, desirable, agreeable, pleasing, connected with the worldly pleasures of the flesh. Sadness arises when you regard it as a loss to lose such ideas, or when you recollect ideas you formerly lost that have passed, ceased, and perished. Such sadness is called domestic sadness. These are the six kinds of domestic sadness.

And in this context what are the six kinds of renunciate sadness? When you’ve understood the impermanence of sights—their perishing, fading away, and cessation—you truly understand through right understanding that both formerly and now all those sights are impermanent, suffering, and perishable. Upon seeing this, you give rise to longing for the supreme liberations: ‘Oh, when will I enter and remain in the same dimension that the noble ones enter and remain in today?’ When you give rise to longing for the supreme liberations like this, sadness arises because of the longing. Such sadness is called renunciate sadness. When you’ve understood the impermanence of sounds … smells … tastes … touches … ideas—their perishing, fading away, and cessation—you truly understand through right understanding that both formerly and now all those ideas are impermanent, suffering, and perishable. Upon seeing this, you give rise to longing for the supreme liberations: ‘Oh, when will I enter and remain in the same dimension that the noble ones enter and remain in today?’ When you give rise to longing for the supreme liberations like this, sadness arises because of the longing. Such sadness is called renunciate sadness. These are the six kinds of renunciate sadness.

Domestic and renunciate equanimity

§14–15And in this context what are the six kinds of domestic equanimity? When seeing a sight with the eye, equanimity arises for the unlearned ordinary person—a foolish ordinary person who has not overcome their limitations and the results of deeds, and is blind to the drawbacks. Such equanimity does not transcend the sight. That’s why it’s called domestic equanimity. When hearing a sound with the ear … When smelling an odor with the nose … When tasting a flavor with the tongue … When encountering a touch with the body … When knowing an idea with the mind, equanimity arises for the unlearned ordinary person—a foolish ordinary person who has not overcome their limitations and the results of deeds, and is blind to the drawbacks. Such equanimity does not transcend the idea. That’s why it’s called domestic equanimity. These are the six kinds of domestic equanimity.

And in this context what are the six kinds of renunciate equanimity? When you’ve understood the impermanence of sights—their perishing, fading away, and cessation—equanimity arises as you truly understand through right understanding that both formerly and now all those sights are impermanent, suffering, and perishable. Such equanimity transcends the sight. That’s why it’s called renunciate equanimity. When you’ve understood the impermanence of sounds … smells … tastes … touches … ideas—their perishing, fading away, and cessation—equanimity arises as you truly understand through right understanding that both formerly and now all those ideas are impermanent, suffering, and perishable. Such equanimity transcends the idea. That’s why it’s called renunciate equanimity. These are the six kinds of renunciate equanimity. ‘The thirty-six positions of sentient beings should be understood.’ That’s what I said, and this is why I said it.

Relying on this, give up that

§16‘Therein, relying on this, give up that.’ That’s what I said, but why did I say it? Therein, by relying and depending on the six kinds of renunciate happiness, give up and go beyond the six kinds of domestic happiness. That’s how they are given up. Therein, by relying on the six kinds of renunciate sadness, give up the six kinds of domestic sadness. That’s how they are given up. Therein, by relying on the six kinds of renunciate equanimity, give up the six kinds of domestic equanimity. That’s how they are given up. Therein, by relying on the six kinds of renunciate happiness, give up the six kinds of renunciate sadness. That’s how they are given up. Therein, by relying on the six kinds of renunciate equanimity, give up the six kinds of renunciate happiness. That’s how they are given up.

Equanimity based on diversity, equanimity based on unity

§17–20There is equanimity that is diversified, based on diversity, and equanimity that is unified, based on unity.

And what is equanimity based on diversity? There is equanimity towards sights, sounds, smells, tastes, and touches. This is equanimity based on diversity.

And what is equanimity based on unity? There is equanimity based on the dimensions of infinite space, infinite consciousness, nothingness, and neither perception nor non-perception. This is equanimity based on unity.

Therein, relying on equanimity based on unity, give up equanimity based on diversity. That’s how it is given up. Relying on not being determined by that, give up equanimity based on unity. That’s how it is given up. ‘Therein, relying on this, give up that.’ That’s what I said, and this is why I said it.

The Teacher’s equanimity

§21–24‘The Noble One cultivates the establishment of mindfulness in three cases, by virtue of which they are a Teacher worthy to instruct a group.’ That’s what I said, but why did I say it?

The first case is when the Teacher teaches Dhamma to his disciples out of kindness and sympathy: ‘This is for your welfare. This is for your happiness.’ But their disciples don’t want to listen. They don’t actively listen or try to understand. They proceed having turned away from the Teacher’s instruction. In this case the Realized One is not unhappy, he does not feel unhappiness. He remains unfestering, mindful and aware. This is the first case in which the Noble One cultivates the establishment of mindfulness.

The next case is when the Teacher teaches Dhamma to his disciples out of kindness and sympathy: ‘This is for your welfare. This is for your happiness.’ And some of their disciples don’t want to listen. They don’t actively listen or try to understand. They proceed having turned away from the Teacher’s instruction. But some of their disciples do want to listen. They actively listen and try to understand. They don’t proceed having turned away from the Teacher’s instruction. In this case the Realized One is not unhappy, nor is he happy. Shunning both unhappiness and happiness, he remains equanimous, mindful and aware. This is the second case in which the Noble One cultivates the establishment of mindfulness.

The next case is when the Teacher teaches Dhamma to his disciples out of kindness and sympathy: ‘This is for your welfare. This is for your happiness.’ And their disciples want to listen. They actively listen and try to understand. They don’t proceed having turned away from the Teacher’s instruction. In this case the Realized One is happy, he does feel happiness. He remains unfestering, mindful and aware. This is the third case in which the Noble One cultivates the establishment of mindfulness. ‘The Noble One cultivates the establishment of mindfulness in three cases, by virtue of which they are a Teacher worthy to instruct a group.’ That’s what I said, and this is why I said it.

Eight directions of training

§25–28‘Of all meditation tutors, it is he that is called the supreme guide for those fit for training.’ That’s what I said, but why did I say it? Driven by an elephant trainer, an elephant in training proceeds in just one direction: east, west, north, or south.

Driven by a horse trainer, a horse in training proceeds in just one direction: east, west, north, or south. Driven by an ox trainer, an ox in training proceeds in just one direction: east, west, north, or south. But driven by the Realized One, the perfected one, the fully awakened Buddha, a person in training proceeds in eight directions:

Having physical form, they see forms. This is the first direction. Not perceiving physical form internally, they see forms externally. This is the second direction. They’re focused only on beauty. This is the third direction. Going totally beyond perceptions of form, with the disappearance of perceptions of impingement, not focusing on perceptions of diversity, aware that ‘space is infinite’, they enter and remain in the dimension of infinite space. This is the fourth direction. Going totally beyond the dimension of infinite space, aware that ‘consciousness is infinite’, they enter and remain in the dimension of infinite consciousness. This is the fifth direction. Going totally beyond the dimension of infinite consciousness, aware that ‘there is nothing at all’, they enter and remain in the dimension of nothingness. This is the sixth direction. Going totally beyond the dimension of nothingness, they enter and remain in the dimension of neither perception nor non-perception. This is the seventh direction. Going totally beyond the dimension of neither perception nor non-perception, they enter and remain in the cessation of perception and feeling. This is the eighth direction. Driven by the Realized One, the perfected one, the fully awakened Buddha, a person in training proceeds in these eight directions.

‘Of all meditation tutors, it is he that is called the supreme guide for those fit for training.’ That’s what I said, and this is why I said it.” That is what the Buddha said. Satisfied, the mendicants approved what the Buddha said.
