The Udana (“Inspired Utterances”) is a book of the Pali Canon made up of 80 short suttas, each ending in a spontaneous verse of insight — an udana — ascribed to the Buddha.

It is home to some of the most-quoted short teachings in Buddhism, including the parable of the blind men and the elephant and the terse liberation-instruction to Bahiya. It belongs to the treasury of early Buddhist scripture.

What is the Udana in the Pali Canon?

The Udana is one of the small jewels of the canon. Like the Sutta Nipata, it is a book of the Khuddaka Nikaya — the “Minor Collection” of shorter works within the Sutta Pitaka of the Pali Canon. Its charm is its form: it collects short episodes from the Buddha’s life, each ending in a heartfelt verse that wells up, as the tradition tells it, spontaneously from his insight. These exclamations — the udanas that give the book its name — compress deep teaching into a few luminous lines, which is why so many of them have become among the most beloved and widely quoted words in Buddhism. Bhikkhu Sujato, whose SuttaCentral translation is used throughout below, renders the book’s title “Heartfelt Sayings” — and because that translation is dedicated to the public domain, the episodes can be quoted here at length rather than only described. Below, the best known of the eighty are taken in the collection’s own order, each with the setting the sutta gives it, and with the Pali behind the English noted wherever a word is doing more work than it appears to.

What an “udana” is

The word udana means an inspired or heartfelt utterance — a spontaneous exclamation arising from a moment of deep understanding or feeling. In this collection, the pattern is unvarying and lovely: a short prose passage sets a scene — an encounter, an event, a question — and then the Buddha responds not with a lecture but with a brief, poetic verse of insight. It is teaching by exclamation rather than by argument.

(A note for the careful: “udana” is also the name of a genre of scripture in the traditional list of the “nine limbs” of the Buddha’s teaching. This page is about the specific book — one collection of such utterances — not the wider category.)

The structure

The Udana has a satisfying, almost architectural regularity. It contains exactly 80 suttas, arranged in 8 chapters (vaggas) of 10 suttas each. Every one of the eighty follows the same shape — the brief narrative frame, then the concluding inspired verse — so that reading it is like turning the pages of a book of eighty small illuminations, each a scene and a saying.

How the collection opens (Ud 1.1)

The Udana begins where the tradition begins. The Buddha is still at Uruvela, at the root of the tree of awakening on the bank of the Nerañjara, seven days into what the text calls the bliss of freedom; in the first part of the night he goes through dependent origination in forward order, from ignorance to old age and death. Then comes the first heartfelt saying in the book.

Two words carry it. Brāhmaṇa — “brahmin” — is used here as the early texts habitually repurpose it: not a man of the priestly class but anyone who has done the work, and Sujato keeps the loaded word rather than smoothing it into “sage”. And “each thing and its cause” renders sahetudhamma, a thing-together-with-its-condition — so what has just become clear is the causal chain the prose has run through in full immediately before. The chain itself is explained on the dependent-origination page; what the Udana adds is the moment it was seen.

Bahiya, and the shape of an udana sutta (Ud 1.10)

The tenth sutta of the first chapter is the most quoted in the book. Bahiya of the Bark Cloth, an ascetic honoured at Suppāraka on the west coast, is told by a deity — a former relative — that he is neither perfected nor on the path to it, and sets out for Savatthi. He reaches the Buddha in the middle of an almsround, and is twice told it is not the time.

The plea is made three times and refused twice, which is worth noticing because Bahiya’s stated reason turns out to be literal: a cow with a calf kills him soon after the Buddha walks away. The four-clause instruction the Buddha gives him has its own page here, in Ṭhānissaro Bhikkhu’s translation: “In the seen, only the seen”. The two translators part company on its third term, muta, which Ṭhānissaro renders “sensed” and Sujato “thought”. Ṭhānissaro’s note on the sutta also records the commentarial reckoning of the distance Bahiya covered: 120 leagues.

The udana itself comes later, and not to Bahiya. He is already dead; the mendicants have asked where he was reborn.

This verse, not the famous instruction, is what makes the episode part of this collection. The four things named are the standard early list of what a physical world is made of; where they na gādhati — “have no footing”, a phrase Sujato and Ṭhānissaro translate identically — there is no ground for anything to stand on, which is an answer to the question the mendicants actually asked. The verse then denies light and denies darkness in the same breath, so the “where” it names cannot be pictured as a dark somewhere either; Sujato’s note on the line points to a close parallel in the Kaṭha Upaniṣad (2.2.15). The release it ends on runs past “forms and formless” and past “pleasure and pain” alike, rather than resting anywhere inside them.

Mucalinda and seven days of rain (Ud 2.1)

Chapter two opens with the episode Buddhist sculpture has loved best, and it shows the collection’s form entire within a page. First the scene.

Sujato renders nāga as “dragon king”; other translators leave the Pali word standing as “naga”, and the being meant is the cobra-formed water spirit of Indian myth (see nagas). Nothing is asked here and nothing is taught: the whole episode is one creature’s protectiveness through a week of unseasonal rain in the weeks after the awakening. It became one of the standard Buddha images of Cambodia and Thailand — the figure seated on coils beneath a spread hood.

Then the saying.

The Pali builds a ladder of four kinds of sukha — sukho viveko, abyāpajjaṁ sukhaṁ, sukhā virāgatā, and above them paramaṁ sukhaṁ, the ultimate. What stands at the top is the removal of asmimāna, the conceit “I am”: a technical term rather than ordinary vanity, naming the residual sense of being a self that the early lists count among the last fetters to go, uprooted only at full awakening. Set against a storm the Buddha appears not to have noticed, the verse quietly says what those seven days of sitting were — not endurance, but ease.

The blind men and the elephant (Ud 6.4)

The sutta the Udāna is best known for outside Buddhism is also the one most often retold against its own grain. Its frame is a dispute: ascetics and wanderers of other religions in Sāvatthī, each closing his position with the formula idameva saccaṁ moghamaññaṁ — this is the only truth, anything else is futile. The king’s demonstration answers them, and the Buddha’s closing verse names the fault as ekaṅgadassino, seeing one limb only. That is why the popular reading — every tradition holding a part of the same elephant — inverts the discourse: the men holding one part each are the disputants, and they are the ones called blind.

We give the discourse in full, with the nine similes, the detail that the men come to blows, and the reception history of the pluralist misreading, on our page about the blind men and the elephant.

The last chapter: extinguishment (Ud 8.1 and 8.3)

The eighth and final chapter opens with four suttas on nibbana, each set at Jeta’s Grove and each with the same frame: the Buddha is giving a Dhamma talk about extinguishment, the mendicants are listening closely, and an utterance follows. The first is the most sweeping sentence in the collection.

“Dimension” renders āyatana, the same word used elsewhere for the six sense fields: a sphere or base rather than a place, though English can hardly carry it without sounding like somewhere to go. The denials run in order through the four elements, then the four formless attainments — the highest states a meditator can reach — then the cosmos itself; the closing string is appatiṭṭhaṁ, appavattaṁ, anārammaṇaṁ, unestablished, not proceeding, without object. What nirvana positively is belongs to What is nirvana?. The Udana’s contribution is this refusal to make it a somewhere.

Two suttas later comes the passage most often quoted when nirvana is under discussion.

Anyone who knows this passage in English will notice that Sujato does not say “There is, monks, an unborn”. The Pali behind it is four negated past participles, ajātaṁ abhūtaṁ akataṁ asaṅkhataṁ, and the sentence built on them is conditional — almost a piece of formal reasoning: were there no unconditioned, no escape from the conditioned could be found. The threefold repetition is not translator’s padding; it is the shape the argument is recited in, negative, hypothetical, then positive.

How the translations differ

The difference is grammatical before it is doctrinal. Ireland and Ṭhānissaro keep the past participle, which in English reads as a thing that was never born; Sujato’s “freedom from rebirth” takes the four words as naming an absence, which avoids implying some hidden eternal something standing behind the world. Ṭhānissaro defends the participle in a note on the passage, against scholars who would render ajātaṁ as “without birth”: he argues that the sentence contrasts the unconditioned with the fabricated rather than with transmigration, and so keeps what he calls “the straight grammatical reading”. What turns on the choice is whether the line describes a state one arrives at, or states only that release is possible — which is why What is nirvana? gives it in Ṭhānissaro’s wording and this page gives it in Sujato’s.

Why the Udana matters

The Udana matters because it shows the Buddha not as a distant systematiser but as a living teacher responding to the moment — and because it holds, in a handful of short episodes, some of the most portable wisdom in the tradition. The Bahiya instruction is a whole meditation practice in a sentence; the blind men and the elephant is a lifelong caution against certainty. Small as it is, the Udana punches far above its weight.

Read the whole Udana

All eighty suttas are online in full in Bhikkhu Sujato’s translation at SuttaCentral, which is public domain; Access to Insight carries John D. Ireland’s and Ṭhānissaro Bhikkhu’s versions of many of the same suttas for comparison. It is short enough to read in an evening, and it repays being read in order rather than dipped into.
