The Buddha alone, addressing the assembled mendicants
Form
A four-step logical chain (impermanent, therefore suffering, therefore not-self, therefore to be seen as not mine) run once in full for each aggregate
Length
~2 minutes to read
Northern parallel
A rough counterpart may exist in the Chinese Saṃyukta-āgama (T99), though this reading guide does not assert a specific matching sutra number
Difficulty
★★☆☆☆ — opens the vagga's most explicitly logical sub-section
Why this discourse
Where SN 22.12-14 stated each of the three marks as an independent, unargued claim, this discourse is where the vagga finally spells out how they connect: form is impermanent; what's impermanent is suffering; what's suffering is not-self; and what's not-self should be seen with right understanding as “this is not mine, I am not this, this is not my self.” The chain runs in one direction only — from impermanence toward the negation of self — and it is this exact four-link sequence that SN 22.16 and SN 22.17 will each shorten by one step, entering the chain progressively further along.
Reading guide
The logical chain, spelled out for the first time
This is the first discourse in the book to state outright the reasoning that SN 22.12-14 left implicit: impermanence entails suffering, suffering entails not-self, and not-self entails a specific way of seeing — “this is not mine, I am not this, this is not my self,” the exact negated formula SN 22.8's learned noble disciple used earlier in the book. Each link depends on the one before it, run through once in full for form and then for each remaining aggregate.
Why the chain moves in only one direction
The chain argues impermanent → suffering → not-self → not-mine, never the reverse. This direction matters: it is not claimed that everything not-self is therefore suffering, or that everything suffering is therefore impermanent (both claims would be false — nibbāna is sometimes discussed elsewhere as not-self without being suffering). The argument works specifically because form, feeling, perception, choices, and consciousness are already known to be impermanent, and the chain traces only what follows from that starting point.
An instruction, not merely a description
The chain's final link is phrased as a prescription rather than an observation: what is not-self “should be truly seen with right understanding like this” (yathābhūtaṁ sammappaññāya daṭṭhabbaṁ) — naming a specific practice (seeing) rather than simply stating a further fact. The three marks are presented here as building toward something to be done, not only something to be known.
Opening a matched trio of decreasing length
This discourse states all four links in full for every aggregate. SN 22.16 immediately after it will begin one link further along the chain, at suffering rather than impermanence, and SN 22.17 will begin at not-self itself — the same destination reached from three different, progressively shorter starting points, worth reading as a matched set rather than as three unrelated discourses.
Key terms
yad aniccaṁ taṁ dukkhaṁ — “what is impermanent is suffering” — the chain's first link, the canonical formula already invoked by name in the previous vagga's reading guides.
yaṁ dukkhaṁ tadanattā — “what is suffering is not-self” — the chain's second link, completing the traditional three-mark sequence.
yathābhūtaṁ sammappaññāya daṭṭhabbaṁ — “should be truly seen with right understanding” — the chain's final, prescriptive link, naming a practice rather than stating a further fact.
n'etaṁ mama, nesohamasmi, na meso attā — “this is not mine, I am not this, this is not my self” — the exact content of that seeing, identical to SN 22.8's negated formula earlier in the book.
tilakkhaṇa — the “three marks” — impermanence, suffering, and not-self, whose logical interdependence this discourse states explicitly for the first time in the book.
The text
The discourse in full. Three elided repetitions (feeling, perception, and choices, each following the same four-link chain spelled out in full for form and consciousness) are given exactly as bilara-data preserves them. Translation: Bhikkhu Sujato (CC0, SuttaCentral).
§1At Sāvatthī. “Mendicants, form is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’
§2Consciousness is impermanent. What’s impermanent is suffering. What’s suffering is not-self. And what’s not-self should be truly seen with right understanding like this: ‘This is not mine, I am not this, this is not my self.’ Seeing this … They understand: ‘… there is nothing further for this place.’”

Question 1 of 10
What four-step chain does this discourse spell out for the first time?
Correct: A. The reasoning SN 22.12-14 left implicit as three separate direct claims.
Question 2 of 10
In which direction does this discourse's chain run?
Correct: A. The argument works specifically starting from the known impermanence of the aggregates.
Question 3 of 10
What is the chain's final link phrased as?
Correct: A. Yathābhūtaṁ sammappaññāya daṭṭhabbaṁ — naming a practice, not just adding information.
Question 4 of 10
What exact formula does the chain's final link specify?
Correct: A. Identical to SN 22.8's negated formula from earlier in the book.
Question 5 of 10
How does this discourse relate to SN 22.16 and SN 22.17 immediately after it?
Correct: A. SN 22.16 begins at suffering; SN 22.17 begins at not-self itself.
Question 6 of 10
Why does the discourse not claim the chain also runs in reverse?
Correct: A. The chain works specifically because the aggregates are already known to be impermanent.
Question 7 of 10
How many aggregates does this discourse's chain apply to?
Correct: A. Feeling, perception, and choices are elided but follow the same pattern.
Question 8 of 10
Where is this discourse set?
Correct: A. Continuing the same setting as the vagga's other discourses.
Question 9 of 10
What formula from earlier in the book does this discourse's final link recall?
Correct: A. The identical negated formula, now reached through explicit logical argument rather than direct instruction.
Question 10 of 10
What comes immediately after this discourse?
Correct: A. The second term of this three-discourse matched set.
