The teaching in one sentence
A doctrine that denies any power to deeds, action, and energy is named the worst of all rival teachings, and the discourse does not soften its language in saying so.
Not Kesakambalī, but a different "hair blanket"
The discourse’s title comes from its opening simile, a literal hair blanket — the coarsest, least comfortable cloth available. It is worth being precise about this: the target is not Ajita Kesakambalī, the materialist teacher of that name known from DN 2’s list of six rivals. The person actually named here is Makkhali, called “the bamboo-staffed ascetic” in Sujato’s translation, and the hair-blanket connection is a shared word for coarse cloth, not a shared identity.
Who Makkhali was
Makkhali Gosāla, founder of the Ājīvika movement, is one of the six teachers DN 2 has King Ajātasattu describe in detail: a strict determinist who taught that purification and corruption alike happen without cause, on a timetable no effort can change. AN 3.137’s complaint targets exactly this: if nothing anyone does has any power, then striving itself is pointless, and the entire Buddhist path — built on exactly the opposite premise — collapses if he is right.
A doctrine argued against by continuity, not just logic
The Buddha’s refutation is unusual in its shape: past Buddhas taught the efficacy of deeds, future Buddhas will teach it, and the present Buddha teaches it now. Makkhali is set not merely against one teacher’s opinion but against every awakened teacher there has ever been or will be — an argument from unanimity across time rather than an argument from first principles.
A trap at the river's mouth
The closing image is harsher than the hair blanket that opened the discourse. A trap set at a river’s mouth catches every fish that passes, indiscriminately, causing “harm, suffering, calamity, and disaster for many.” Applied to Makkhali, the image says his teaching does not merely fail to help; it actively catches whoever encounters it, regardless of that person’s own merit or intention.
Reading the harshness honestly
This is some of the most severe language the Buddha uses about a named rival anywhere in this collection, and it should not be softened for a modern audience uncomfortable with religious polemic. The stakes explain the tone: a doctrine that denies any power to effort is not a minor disagreement about method but a direct denial of the premise every other discourse in this collection depends on. Ancient religious debate in this milieu was not gentle, and this discourse is a clear example of that fact rather than an exception to it.
Key terms
The text
The worst kind of cloth, the worst kind of doctrine
§1“Mendicants, a hair blanket is said to be the worst kind of woven cloth. It’s cold in the cold, hot in the heat, ugly, smelly, and unpleasant to touch. In the same way, the teaching of the bamboo-staffed ascetic is said to be the worst of all the doctrines of the various ascetics and brahmins.
Makkhali named and refuted
§2The bamboo-staffed ascetic, that futile man, has this doctrine and view: ‘There is no power in deeds, action, or energy.’ Those who were perfected ones, fully awakened Buddhas in the past also taught the efficacy of deeds, action, and energy. But the bamboo-staffed ascetic opposes them by saying: ‘There is no power in deeds, action, or energy.’ Those who will be perfected ones, fully awakened Buddhas in the future will also teach the efficacy of deeds, action, and energy. But the bamboo-staffed ascetic opposes them by saying: ‘There is no power in deeds, action, or energy.’ I too, the perfected one, the fully awakened Buddha in the present, teach the efficacy of deeds, action, and energy. But the bamboo-staffed ascetic opposes me by saying: ‘There is no power in deeds, action, or energy.’
A trap at the river's mouth
§3It’s like a trap set at the mouth of a river, which would bring harm, suffering, calamity, and disaster for many fish. In the same way that futile man the bamboo-staffed ascetic is a trap for humans, it seems to me. He has come into the world for the harm, suffering, calamity, and disaster of many beings.”
