Tatiyasutta — Parisuddhavagga — the thirteenth chapter of the Tens, the Chapter on Purified Things
Setting
None stated in the source
Speakers
The Buddha alone, addressing the mendicants
Form
A single-sentence claim, then the familiar ten-item list
Length
under 1 minute to read
Difficulty
★☆☆☆☆ — the third of this chapter's near-identical single claims
Why this discourse
The third claim in this chapter's sequence shifts from existence itself to value: even granting that something resembling these ten factors might occur elsewhere, only within this training do they actually pay off.
Reading guide
The teaching in one sentence
The ten right factors, from right view to right freedom, are not very fruitful and beneficial anywhere except within the Holy One's own training.
From existence to value
AN 10.123 and 10.124 concerned whether the ten factors are pure or whether they arise at all outside this training; this discourse asks a different kind of question — not whether they exist elsewhere, but whether they are worth anything elsewhere — and answers that their fruitfulness, too, is exclusive to this training.
Fruitful and beneficial, a set pairing
“Very fruitful and beneficial” (mahapphalā mahānisaṁsā) is a stock phrase already met elsewhere in this project describing outcomes worth pursuing; applying it here to the ten factors themselves, rather than to a practice built on them, makes the factors' own value, not merely their results, the discourse's explicit subject.
A claim that will return doubled
This exact claim — fruitfulness restricted to this training — reappears later in the chapter at AN 10.129, there combined with the further condition of being “developed and cultivated” first introduced at AN 10.128.
Key terms
mahapphalā mahānisaṁsā — “very fruitful and beneficial” — this discourse's own claim, a stock phrase for outcomes genuinely worth pursuing.
nāññatra sugatavinayā — “not apart from the Holy One's training” — the same exclusivity clause repeated a third time.
sammāvācā — “right speech” — the third factor, unchanged across every list in this chapter.
sammāsamādhi — “right immersion” — the eighth factor, the classical eightfold path's own final member before this chapter's two additional factors.
The text
The discourse in full: the single claim, and the familiar ten-item list. Translation: Bhikkhu Sujato (CC0, SuttaCentral).
Not fruitful apart from this training
§1“Mendicants, these ten things are not very fruitful and beneficial apart from the Holy One’s training. What ten? Right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, right immersion, right knowledge, and right freedom. These are the ten things that are not very fruitful and beneficial apart from the Holy One’s training.”
