The Poisoned Arrow
Lecture Notes
An ultimatum
The monk Māluṅkyaputta sits down one afternoon and issues an ultimatum: the Buddha has never declared whether the world is eternal or not, finite or infinite, whether the soul and the body are the same or different, whether the Realized One exists after death, does not exist, both, or neither. If the Buddha will not declare these to him, he will renounce the training and return to lay life. This is a student trying to set the curriculum by force.
"Who are you to disavow?"
The Buddha's first move is to point out that he never promised what Māluṅkyaputta is now demanding. "Did I ever say to you, come lead the spiritual life under me and I will declare these things to you?" No. "Then, misguided man, who are you to disavow anyone?" A teacher is not obligated to answer every question a student insists is essential, merely because the student insists on it — especially a question the teacher never agreed to answer in the first place.
The poisoned arrow
Then the simile that gives the sutta its fame. A man is struck by a poisoned arrow; his family brings a surgeon; the man says he will not have the arrow removed until he knows the name and clan of the man who shot him, whether he was tall or short, dark or light, what village he came from, what kind of bow, what the bowstring was made of, what kind of arrow, what kind of feathers fletched it. That man would die, the Buddha says, without ever learning any of it — the questions themselves were never the obstacle to treatment. They were a way of never getting treated.
A medicine, not a metaphysics
The Buddha explains: whether the world is eternal or not, there is still birth, aging, death, sorrow, lamentation, pain, sadness, and distress — "the raising of these I declare, right here and now." He has left the ten questions undeclared precisely because they do not lead to disenchantment, dispassion, cessation, peace, direct knowledge, awakening, Nibbāna. What he has declared — suffering, its origin, its cessation, the path to its cessation — is declared because it does lead there. The line he draws is not arbitrary; it is drawn by what treats the wound.
- Declining a question is sometimes the more honest teaching move. The Buddha never claims not to know; he explains, in full, why the question does not belong in this curriculum.
- A student's insistence does not create an obligation. "Who are you to disavow?" — the Buddha never promised to answer everything, and being asked forcefully enough does not retroactively create that promise.
- The line between what is and isn't taught is principled, not arbitrary. Ten questions are set aside for the same explicit reason: they do not lead toward the relief of suffering. That is a real criterion, stated out loud, not evasion.

MN 63 — The Shorter Discourse with Māluṅkya
A monk threatens to leave unless the Buddha answers the great metaphysical questions; the Buddha replies with the famous simile of the poisoned arrow, teaching only what defeats suffering.
Read the sutta →Discussion Questions
- Have you ever refused to answer a student's question — not because you didn't know, but because you judged it wouldn't actually help them? How did you explain that refusal, if you did at all?
- The Buddha gives a specific, stated criterion for what he will and won't teach (does it lead toward the relief of suffering?). What is the equivalent criterion, if any, in your own subject — what decides what belongs in the curriculum and what doesn't?
- Is there a risk in this teaching method — that "this question isn't useful" becomes a convenient way to dodge anything difficult? How does the poisoned-arrow simile guard against that risk, or does it?
- Māluṅkyaputta's demand comes from a real place — he is genuinely troubled by not knowing. Does the Buddha's answer actually address that trouble, or does it simply redirect it? Is redirection itself a legitimate teaching response to genuine distress?
AssignmentChoose one · half to one page · bring it next session
Recall a question a student has asked you that you judged unproductive to answer directly ("will this be on the test," or something further afield). Write out, in the Buddha's manner, both the refusal and the reason for it — stated as plainly as he states his.
In half a page, state the criterion you actually use (even if you've never said it out loud) for what belongs in your teaching and what doesn't. Then test it against one real example of something you chose to leave out.
Self-Check
The sutta's own page has a ten-question quiz covering the full text. Take it there before moving on.
Session 6: I Have Stopped
From refusing a question to facing a killer unarmed. MN 86 shows the Buddha's teaching method pushed to its limit — meeting the least teachable person imaginable, with almost no words at all.
