The teaching in one sentence
What is named a ‘factor of trying for purity’ is not the purity itself but the ongoing enthusiasm applied toward completing or sustaining it.
Ānanda teaches without being asked
The setting is brief and the initiative unusual: several villagers from Sāpūga come to Ānanda, sit down, and Ānanda addresses them directly, without recording any question from them at all. He announces that these four factors have been rightly explained by the Blessed One… in order to purify sentient beings, to get past sorrow and crying, to make an end of pain and sadness, to discover the system, and to realize extinguishment — and then teaches them.
Four purities, in the collection’s familiar order
Purity of ethics is the standard formula: restrained by the monastic code, well-conducted, seeing danger in the slightest fault. Purity of mind is the four absorptions. Purity of view is the four noble truths. Purity of freedom is described as what happens when a noble disciple who already has the first three ‘detaches their mind from things that arouse greed, and frees their mind from things that it should be freed from’, experiencing perfect freedom as a result.
This is the same progression met before in this nipāta — ethics, then immersion, then view, then freedom — here given its fourth term explicitly built on the first three rather than standing independently.
The definition that actually matters
Each of the four attainments is followed by an identical second definition, and this is where the discourse’s real content sits. After purity of ethics is defined, the mendicant is said to think: I will fulfill such purity of ethics, or, if it’s already fulfilled, I’ll support it in every situation by wisdom. Their enthusiasm for that — effort, zeal, vigor, perseverance, mindfulness, and situational awareness — is called the factor of trying to be pure in ethics.
Read that carefully: the factor of trying is not the purity of ethics. It is the effort applied toward it. And crucially, the same effort is called for in both branches of the thought — whether the purity is not yet fulfilled, or already is. Nothing here describes a finish line after which the enthusiasm can relax.
That structure repeats identically for mind, view, and freedom. Four different attainments, one unchanging attitude toward each of them: keep applying the same effort, zeal, vigor, perseverance, mindfulness, and situational awareness, irrespective of whether the goal has been reached.
Why this matters for how the discourse should be read
A reader skimming this discourse could easily mistake it for one more restatement of ethics, immersion, view, and freedom — a set already met at AN 4.194’s neighbors in this nipāta. That would miss what the title actually names: not the four purities, but padhāniyaṅga, the factor of striving, attached to each.
The discourse’s real claim is about the shape of ongoing practice rather than about the content of the four goals. Reaching a purity does not end the work; it changes what the same enthusiasm is now supporting. A mendicant who has fulfilled purity of ethics does not stop applying effort to it — the effort simply shifts from building it to maintaining it ‘in every situation by wisdom’.
Where this echoes elsewhere in the Fours
This six-item list of enthusiasm — chanda, vāyāma, ussāha, ussoḷhī, appativāni, sati, sampajañña — is not the same vocabulary as the faculties or powers catalogued in the Indriyavagga several chapters back, but it does the same kind of work: naming what has to remain active for an attainment to be more than a one-time event.
The discourse gives no indication of how the villagers of Sāpūga responded, and ends simply by restating the four factors and their purpose. Unlike several other discourses in this chapter, there is no conversion scene here — only a teaching, offered and recorded.
Key terms
The text
Ānanda addresses the villagers
§1At one time Venerable Ānanda was staying in the land of the Koliyans, where they have a town named Sāpūga. Then several Koliyans from Sāpūga went up to Ānanda, bowed, and sat down to one side. Then Venerable Ānanda said to them: “Byagghapajjas, these four factors of trying to be pure have been rightly explained by the Blessed One, who knows and sees, the perfected one, the fully awakened Buddha. They are in order to purify sentient beings, to get past sorrow and crying, to make an end of pain and sadness, to discover the system, and to realize extinguishment. What four? The factors of trying to be pure in ethics, mind, view, and freedom.
Trying to be pure in ethics
§2And what is the factor of trying to be pure in ethics? It’s when a mendicant is ethical, restrained in the monastic code, conducting themselves well and resorting for alms in suitable places. Seeing danger in the slightest fault, they keep the rules they’ve undertaken. This is called purity of ethics. They think: ‘I will fulfill such purity of ethics, or, if it’s already fulfilled, I’ll support it in every situation by wisdom.’ Their enthusiasm for that—their effort, zeal, vigor, perseverance, mindfulness, and situational awareness—is called the factor of trying to be pure in ethics.
Trying to be pure in mind
§3And what is the factor of trying to be pure in mind? It’s when a mendicant, quite secluded from sensual pleasures, secluded from unskillful qualities, enters and remains in the first absorption … second absorption … third absorption … fourth absorption. This is called purity of mind. They think: ‘I will fulfill such purity of mind, or, if it’s already fulfilled, I’ll support it in every situation by wisdom.’ Their enthusiasm for that—their effort, zeal, vigor, perseverance, mindfulness, and situational awareness—is called the factor of trying to be pure in mind.
Trying to be pure in view
§4And what is the factor of trying to be pure in view? Take a mendicant who truly understands: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’. This is called purity of view. They think: ‘I will fulfill such purity of view, or, if it’s already fulfilled, I’ll support it in every situation by wisdom.’ Their enthusiasm for that—their effort, zeal, vigor, perseverance, mindfulness, and situational awareness—is called the factor of trying to be pure in view.
Trying to be pure in freedom
§5And what is the factor of trying to be pure in freedom? That noble disciple—who has these factors of trying to be pure in ethics, mind, and view—detaches their mind from things that arouse greed, and frees their mind from things that it should be freed from. Doing so, they experience perfect freedom. This is called purity of freedom. They think: ‘I will fulfill such purity of freedom, or, if it’s already fulfilled, I’ll support it in every situation by wisdom.’ Their enthusiasm for that—their effort, zeal, vigor, perseverance, mindfulness, and situational awareness—is called the factor of trying to be pure in freedom. These four factors of trying to be pure have been rightly explained by the Blessed One, who knows and sees, the perfected one, the fully awakened Buddha. They are in order to purify sentient beings, to get past sorrow and crying, to make an end of pain and sadness, to discover the system, and to realize extinguishment.”
