The teaching in one sentence
All four ways of asking what remains beyond the six sense fields are rejected, because the question itself extends a kind of elaboration that has nowhere left to attach once those fields have ceased.
The four horns
The classical tetralemma: exists, does not exist, both exists and does not exist, neither exists nor does not exist. Together these four are usually treated as logically exhaustive — there is, on the face of it, no fifth way to answer a yes-or-no question about existence.
Sāriputta answers mā hevaṁ, don’t put it like that, to every one of the four, without elaboration at the time of asking. That refusal, repeated across an apparently exhaustive set of options, is what makes Mahākoṭṭhita press further: if none of the four descriptions fits, how should the statement be understood at all?
What the refusal is refusing
Sāriputta’s eventual answer does not choose a fifth position. It says that all four ways of putting the question are instances of papañca, proliferation — and that asserting any of them, including the negations, is ‘proliferating the unproliferated’, appapañcaṁ papañceti.
Papañca is the elaborating, expanding tendency of a mind working with concepts — taking a bare experience and spinning it into identity, possession, and argument. The term is best known from its long treatment in MN 18, where perception, thought, and proliferation are traced from contact through to conflict over views.
The claim here is precise: the six fields of contact and proliferation have exactly the same scope. The scope of proliferation extends as far as the scope of the six fields of contact; the scope of the six fields of contact extends as far as the scope of proliferation. Where one operates, so does the other, and neither exceeds the other’s reach.
Why a fifth answer would not help
This is the discourse’s hardest move and it deserves to be stated without softening. If proliferation and the six sense fields are coextensive, then any positive or negative claim about what exists beyond those fields is already using the very apparatus — contact-generated conceptual elaboration — whose cessation the question is asking about.
That is why none of the four horns can be affirmed: each one presupposes that the conceptual machinery for asking about existence is still operating in the space where the question locates its object, and the discourse’s premise is that this machinery has exactly the same boundary as the six fields it is asking past.
A fifth logical option is not available because the problem is not with which answer is correct. It is with what a correct answer, of any of the available shapes, would have to presuppose.
The last line
When the six fields of contact fade away and cease with no residue left behind, proliferation stops and is stilled. This is the discourse’s only positive statement, and it is deliberately not a description of a remaining state. It reports an ending — of proliferation, which is to say of the very activity that was generating the question — without characterizing what, if anything, that leaves.
Read against AN 4.171, two discourses back, this closing line uses the identical phrase for cessation: asesavirāganirodhā, fading away and ceasing with no residue. Both discourses describe an ending in the same technical vocabulary and both decline to fill in what comes after with a positive content, for what this reading guide takes to be the same reason: the vocabulary available for filling it in belongs to the very apparatus that has ceased.
What happens next
AN 4.174 gives what looks, at first glance, like the identical exchange — but with Ānanda asking Mahākoṭṭhita the same four questions, and Mahākoṭṭhita giving Sāriputta’s answer back, word for word. Read together, the two discourses show the teaching passing from one senior disciple to the next intact, refusal for refusal, analysis for analysis.

The text
Mahākoṭṭhita’s question
§1Then Venerable Mahākoṭṭhita went up to Venerable Sāriputta, and exchanged greetings with him. When the greetings and polite conversation were over, Mahākoṭṭhita sat down to one side, and said to Sāriputta: “Reverend, when the six fields of contact have faded away and ceased with no residue left behind, does something else still exist?”
Four refusals
§2“Don’t put it like that, reverend.” “Does something else no longer exist?” “Don’t put it like that, reverend.” “Does something else both still exist and no longer exist?” “Don’t put it like that, reverend.” “Does something else neither still exist nor no longer exist?” “Don’t put it like that, reverend.”
Mahākoṭṭhita restates the puzzle
§3“Reverend, when asked whether—when the six fields of contact have faded away and ceased with no residue left behind—something else still exists, you say ‘don’t put it like that’. When asked whether something else no longer exists, you say ‘don’t put it like that’. When asked whether something else both still exists and no longer exists, you say ‘don’t put it like that’. When asked whether something else neither still exists nor no longer exists, you say ‘don’t put it like that’. How then should we see the meaning of this statement?”
Sāriputta’s answer
§4“In saying that, ‘When the six fields of contact have faded away and ceased with no residue left behind, something else still exists’, you’re proliferating the unproliferated. In saying that, ‘something else no longer exists’, you’re proliferating the unproliferated. In saying that, ‘something else both still exists and no longer exists’, you’re proliferating the unproliferated. In saying that, ‘something else neither still exists nor no longer exists’, you’re proliferating the unproliferated. The scope of proliferation extends as far as the scope of the six fields of contact. The scope of the six fields of contact extends as far as the scope of proliferation. When the six fields of contact fade away and cease with no residue left behind, proliferation stops and is stilled.”
