Speakers
The Buddha alone, addressing the mendicants
Form
A list of four, stated once
Length
under a minute to read
Northern parallel
This four-item sequence is foundational and widely cited across Buddhist traditions; this reading guide does not assert a specific matching sutra number
Difficulty

Why this discourse
Four things lead to the growth of wisdom: associating with a true person, hearing the true teaching, applying the mind rationally, and practicing in line with what has been learned. This is a compact causal sequence, moving from an external relationship inward to a person's own mental habit and then out again into sustained practice, and it is worth reading as one continuous chain rather than four independent items.
Reading guide
The teaching in one sentence
Wisdom grows through relying on a true person, hearing the true teaching from them, applying the mind to it rationally, and then practicing in line with what has been understood.
A chain, not a checklist
Sappurisasaṁseva, saddhammassavana, yoniso manasikāra, dhammānudhammappaṭipatti — associating with a true person, listening to the true teaching, rational application of mind, and practicing in line with the teaching. Each item depends on the one before it: there is nothing to hear without first finding someone worth listening to; nothing to reflect on rationally without first hearing it; and no practice in line with the teaching without first having reflected on it rationally enough to understand what it actually asks.
‘Sappurisa’, a vocabulary that keeps returning
The first link in the chain uses the same sappurisa, ‘true person’, vocabulary that named the Sappurisavagga several chapters back and closed the previous chapter at AN 4.242, on the benefits of relying on a true person. Wisdom’s growth here begins with exactly the relationship AN 4.242 already named as the source of growth in ethics, immersion, wisdom, and freedom together — this discourse simply isolates wisdom and gives its own causal account of how the relationship produces it.
Rational application, the pivot of the chain
Yoniso manasikāra, literally attending to the origin or root of things, is the chain’s internal turn — the point where an externally received teaching becomes a person’s own active work. Without it, hearing a true teaching produces only information; with it, hearing becomes the ground for practice. The term marks the chain’s hinge between what is received from outside and what a person does with it.
A sequence about to repeat, unusually
This discourse’s exact four terms recur, word for word, at the very next discourse, AN 4.249, under a different frame — not what grows wisdom, but what is very helpful to a human being. The repetition is worth flagging honestly as reuse rather than treating the two discourses as making genuinely separate claims: this chain is evidently considered valuable enough to state twice in immediate succession.
Key terms
sappurisasaṁseva — “associating with a true person” — the same sappurisa vocabulary already met at AN 4.201 and AN 4.242.
saddhammassavana — “hearing the true teaching” — the second link, dependent on having first found a true person to hear it from.
yoniso manasikāra — “rational application of mind”, literally attending to the root or origin — the chain's internal hinge, turning received teaching into a person's own active reflection.
dhammānudhammappaṭipatti — “practicing in line with the teaching” — literally practice in accordance with the teaching's own principle, the chain's final, sustained step.
paññāvuddhi — “the growth of wisdom” — the frame this discourse gives the four-item chain, distinct from the frame AN 4.249 gives the identical chain.

Question 1 of 10
What four things does this discourse say lead to the growth of wisdom?
Correct: B. A causal chain, each item depending on the one before it.
Question 2 of 10
Why does the guide say this list should be read as a chain rather than four independent items?
Correct: B. A continuous sequence, not a checklist.
Question 3 of 10
Where has the sappurisa vocabulary in this discourse's first item already appeared in this series?
Correct: B. Naming the Sappurisavagga and closing the previous chapter at AN 4.242.
Question 4 of 10
What does yoniso manasikāra literally mean, and what role does the guide give it?
Correct: B. Without it, hearing produces only information; with it, hearing becomes the ground for practice.
Question 5 of 10
What happens to this discourse's exact four-item chain at the very next discourse, AN 4.249?
Correct: B. Flagged as reuse, stated twice in immediate succession.
Question 6 of 10
What is the second link in this discourse's chain?
Correct: B. Dependent on first finding a true person to hear it from.
Question 7 of 10
What is the final link in the chain?
Correct: B. The sustained step that follows rational reflection.
Question 8 of 10
What connection does the guide draw between this discourse and AN 4.242?
Correct: B. The same relationship, given a more detailed causal account here.
Question 9 of 10
What does the guide say about treating this discourse and AN 4.249 as making separate claims?
Correct: B. Consistent with this series' practice of naming repeated material honestly.
Question 10 of 10
