The Kālāma Sutta (AN 3.65) is one of the most quoted discourses in all of Buddhism — and one of the most misquoted. In it, the Buddha tells a group of puzzled villagers not to accept a teaching merely because of who says it or how old it is, but to test it in their own experience.

It has earned the nickname “the Buddha’s charter of free inquiry,” and it sounds so modern that it is often pressed into service as proof that Buddhism is a religion of reason. The truth, as usual, is richer than the slogan.

The Setting

The people of Kesaputta, a town of the Kālāma clan, had a problem familiar to anyone today. A stream of wandering teachers passed through, each selling a doctrine and running down the rest. The Kālāmas put the difficulty to the Buddha in their own words:

Notice what they are not asking. They want no doctrine and no credentials — only a way to tell speakers apart. The pile-up of verbs is in the Pali too (khuṁsenti vambhenti paribhavanti omakkhiṁ karonti) — the same run of verbs the Vinaya uses for plain abusive speech, in the rule against insulting a fellow monk (Bu Pc 2, Omasavāda). The discourse’s Pali title on SuttaCentral is the Kesamuttisutta, after the town, while Access to Insight prints it as the Kalama Sutta, after the clan; both name the same discourse. Of all the Buddhist scriptures, few are quoted more often, or more selectively.

The Buddha’s first move is not to answer the question but to license it:

That is an unusual thing for a teacher to say. Doubt — vicikicchā, the word used here — is elsewhere in the canon one of the five hindrances, an obstacle to be cleared before the mind can settle. The Buddha draws a distinction rather than a rule: their doubt has arisen kaṅkhanīye … ṭhāne, in a matter that genuinely warrants it. He does not tell the Kālāmas to stop doubting, and he does not answer, “Believe me — my teaching is the right one.” He tells them their doubt is well placed, then hands them a tool for working it through themselves.

The Ten Grounds

The Buddha answers with a list of ten things not to rely on as sufficient grounds for conviction. Here it is entire, in Bhikkhu Sujato’s translation:

In the Pali each item is governed by mā, “don’t”, and all but the last is a single word or short compound: anussava (what is heard down the line, oral transmission), paramparā (succession, lineage), itikirā (hearsay, “so-they-say”), piṭakasampadāna (what accords with a collection of texts), takkahetu and nayahetu (on the ground of reasoning, on the ground of inference), ākāraparivitakka (turning a matter over in the mind), diṭṭhinijjhānakkhanti (acquiescing in a view you have grown comfortable with), bhabbarūpatā (the appearance of competence) — and last, the teacher’s own standing.

It is a remarkable list. He sets aside not only the obvious authorities — lineage, canonical authority, the prestige of a teacher — but the tools of the philosopher too: logic, inference, deliberation. None of these, on its own, is enough to settle whether a teaching is true and good. It is worth being precise, though: he does not call these things worthless. Scripture and reasoning have their place. He says only that they are not sufficient by themselves to compel belief.

How the translations differ

The list is short and its Pali is compressed, so English versions of it diverge sharply — one reason the sutta is so easy to press into service. Compare the first four grounds:

Most of the weight falls on two words. Anussava is built on hearing (sava) — the same root as suti (Sanskrit śruti), the Brahmanical term for revealed scripture — so Sujato’s “oral transmission” points at an authoritative transmitted tradition, while Ṭhānissaro’s “reports” and Soma Thera’s “repeated hearing” sound closer to rumour. Piṭakasampadāna is harder still: piṭaka means “basket”, and the three-basket collection now called the Pali Canon was assembled after the Buddha’s lifetime, so the phrase cannot be a rejection of that canon. Ṭhānissaro’s blunt “by scripture” — the rendering our own do not go by tradition page carries — is the one that most encourages the reading that the Buddha threw out scripture as such.

The Positive Test

The sentence does not stop at the list. It turns in the same breath to what the Kālāmas should go by — and in the text the negative form comes first:

Four criteria, not one: unskilful (akusala), blameworthy (sāvajja), condemned by the viññū — the discerning, whom Sujato renders “sensible people” and older translations call “the wise” — and harmful in their results. Attanāva jāneyyātha, “you should know for yourselves”, governs all four, including the criterion about other people’s judgement: you are to see for yourself that discerning people condemn a thing, not take a poll.

Then, rather than leaving the criterion abstract, he runs it in public on cases nobody disputes:

The same question is put three times over — for greed, for hate, for delusion — and the Kālāmas answer it themselves each time. This is the discourse’s real argumentative shape, and it disappears when only the famous list is quoted. Notice how narrow the test-bed is: he asks about conduct anyone can watch a person do, not about metaphysics. Nothing in the test requires the Kālāmas to accept a doctrine before they can apply it.

Only once they have reached the verdict for themselves does the positive form arrive:

“Acquire them and keep them” translates upasampajja vihareyyātha — more literally, “having taken them up, you should dwell in them”. Upasampajja is the same verb the canon uses for taking up full ordination and for entering the meditative absorptions: it means moving in, not merely agreeing. What the Kālāmas’ inquiry is meant to produce is a changed life, not a settled opinion.

What It Does Not Say

Here is the honest correction, and it matters. The Kālāma Sutta is frequently quoted as if the Buddha had said: believe nothing, trust no one, work it all out for yourself. He did not.

Look again at the positive test and you will see two safeguards against pure individualism. First, the criterion includes “praised by the wise” — the judgement of those of good character and experience is part of the method, not banished from it. Second, the yardstick is explicitly moral: the question is whether a quality is skillful or unskillful, leading to welfare or to harm — not simply whatever each person happens to prefer. This is not a charter for “my truth is as good as yours.” It is a call for thoughtful, ethical verification — testing teachings against both your own honest experience and the counsel of the wise.

It is also worth noting what the discourse is really about: not abstract metaphysics, but how to live. The Buddha is not inviting the Kālāmas to second-guess every doctrine; he is showing them how to recognise, in their own experience, that greed, hatred, and delusion bring suffering, and their opposites bring peace. That, he suggests, is something anyone can verify.

And the discourse does not end with the test. It ends in meditation:

The same formula then repeats for compassion, rejoicing and equanimity: the four brahmavihāras. “A heart full of love” is mettāsahagatena cetasā, a mind accompanied by mettā, and the person described is an ariyasāvaka, which Sujato renders “noble disciple”. A discourse read as a manifesto for scepticism in fact terminates in loving-kindness practice: the inquiry is not the destination but what clears the ground for it.

Then it closes with an argument the free-thinker’s version drops entirely — four assāsa, consolations, that hold whichever way the metaphysics turns out:

Assāsa is the in-breath of relief; Ṭhānissaro renders it “assurance”, Sujato “consolation”. Two more follow, on whether wrongdoing rebounds on the wrongdoer. The passage is often likened to Pascal’s wager, but the structures differ where it counts: Pascal asks you to believe in order to win the bet, whereas here nothing is believed — the disciple has already put down enmity, and the argument simply observes that no possible state of the world makes that a bad move. It is also quiet evidence against the modern reading. A discourse that had abolished karma and rebirth would have no reason to hedge about them.

Why It Still Resonates

For all the misreading, the genuine spirit of the sutta is real and remarkable. At a time when most religious authority rested on revelation and command, here is a teacher inviting people to check his teaching against their own experience — and staking its truth on whether it actually works. That confidence, that openness to investigation, is part of why Buddhism has so often been called compatible with a scientific outlook, and why many feel they can engage the practice without first “believing” anything at all. The Dhamma, the tradition says, is ehipassiko — “come and see.” The Kālāma Sutta is that invitation, in the Buddha’s own words.

For the body of texts it belongs to, see the Pāli Canon; for the central discourse on mindfulness practice, the Satipaṭṭhāna Sutta; and for the wider question, is Buddhism a religion?

The passage most people know from this sutta, “don’t go by reports, by legends, by traditions…”, has its own page, with the half that is usually left out.

The discourse is short, and everything quoted above is only part of it. Read it whole in Bhikkhu Sujato’s translation on SuttaCentral, or compare Ṭhānissaro Bhikkhu’s and Soma Thera’s renderings on Access to Insight.
