Difficulty
★★★☆☆ — identical reasoning to SN 22.18-19, closing the cause-based trio
Why this discourse
This discourse closes the cause-based trio SN 22.18 opened, and its conclusion is arguably the sharpest of the three: since form is produced by what is not-self, how could it be self? Where SN 22.18 ruled out permanence and SN 22.19 ruled out happiness, this discourse rules out self itself — directly foreclosing the very possibility SN 22.7-8 examined earlier in the book, that an aggregate might be identified with under any of the fourfold or threefold formulas. If even an aggregate's cause is not-self, nothing about the aggregate's own arising could smuggle a genuine self back in.
Reading guide
The trio's final substitution
As in SN 22.18-19, form is named as sharing a quality — here, not-self — with the cause that produces it, closing with the rhetorical question: since form is produced by what is not-self, how could it be self? The argument's shape is identical across all three discourses; only the mark and its ruled-out opposite change.
Foreclosing self at the level of causation itself
This discourse's conclusion connects directly back to SN 22.7-8's earlier analysis of identity view: those discourses examined the various ways a person might regard an aggregate as self, self as having it, or as mine. This discourse forecloses the possibility one level earlier, at the aggregate's own causation — if what produces form is itself not a self, form's own arising offers no opening for a genuine self to be found in it.
Completing a matched pair of trios
With this discourse, the vagga has now built two parallel three-discourse sets on an identical underlying template: SN 22.15-17 telescoped a single logical chain into progressively shorter entry points, while SN 22.18-20 held the argument's length constant and instead varied which of the three marks, paired against its own proper opposite, was being ruled out at the level of cause.
One discourse remaining to close the vagga
With impermanence, suffering, and not-self now argued both directly (SN 22.12-14), through logical derivation (SN 22.15-17), and through causation (SN 22.18-20), the vagga has one discourse left: SN 22.21, where Ānanda asks the Buddha directly what all of this “cessation” the preceding twenty discourses have been building toward actually refers to.
Key terms
hetu paccaya — “cause and reason” — the same phrase from SN 22.18-19, here naming what produces the aggregate as itself not-self.
attā — “self” — the ruled-out opposite in this discourse, completing the trio's sequence of permanent, happiness, and now self.
kuto attā bhavissati — “how could it be self?” — this discourse's closing rhetorical question, the sharpest of the trio's three parallel conclusions.
anattā — “not-self” — applied twice over, to both an aggregate and, distinctly, to whatever produces that aggregate.
sakkāyadiṭṭhi — “identity view” — the broader doctrine SN 22.7-8 examined earlier in the book, which this discourse's causal argument forecloses one level further back, at the aggregate's own arising.
The text
The discourse in full. Three elided repetitions (feeling, perception, and choices, each following the same causal argument 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 not-self. The cause and reason that gives rise to form is also not-self. Since form is produced by what is not-self, how could it be self?
§2Consciousness is not-self. The cause and reason that gives rise to consciousness is also not-self. Since consciousness is produced by what is not-self, how could it be self? Seeing this … They understand: ‘… there is nothing further for this place.’”

Question 1 of 10
What ruled-out opposite does this discourse use, completing the trio's sequence?
Correct: A. Completing the sequence permanent (SN 22.18), happiness (SN 22.19), self (this discourse).
Question 2 of 10
What does this discourse claim about the cause that produces form?
Correct: A. The cause shares the same not-self quality as its effect.
Question 3 of 10
How is the discourse's conclusion phrased?
Correct: A. Parallel in form to SN 22.18 and SN 22.19's closing questions.
Question 4 of 10
How does this discourse's conclusion connect back to SN 22.7-8 earlier in the book?
Correct: A. If what produces form is itself not a self, form's own arising offers no opening for a genuine self.
Question 5 of 10
What position does this discourse hold in its trio, SN 22.18-20?
Correct: A. Completing impermanence (SN 22.18) and suffering (SN 22.19) with not-self.
Question 6 of 10
How do SN 22.15-17 and SN 22.18-20 differ as a pair of matched trios?
Correct: A. Two different structural devices applied to the same three marks.
Question 7 of 10
How many aggregates does this discourse's argument apply to?
Correct: A. Feeling, perception, and choices are elided but follow the same pattern.
Question 8 of 10

Correct: A. Continuing the same setting as the vagga's other discourses.
Question 9 of 10
What discourse comes immediately after this one, closing the vagga?
Correct: A. The vagga's own closing discourse, immediately before Bhāravagga begins at SN 22.22.
Question 10 of 10
What has the vagga now argued impermanence, suffering, and not-self through, across its twenty discourses so far?
Correct: A. SN 22.12-14 (direct), SN 22.15-17 (derivation), SN 22.18-20 (causation).
