1On one occasion the Blessed One was dwelling at Vesālī in the hall with the peaked roof in the Great Wood. Then the male lay follower Vāseṭṭha approached the Blessed One, paid homage to him, and sat down to one side. The Blessed One then said to him:

"Vāseṭṭha, observed complete in eight factors, the uposatha is of great fruit and benefit, extraordinarily brilliant and pervasive. And how is the uposatha observed complete in eight factors, so that it is of great fruit and benefit, extraordinarily brilliant and pervasive?.
All as in 8:42, including the verses.

1Ekaṁ samayaṁ bhagavā vesāliyaṁ viharati mahāvane kūṭāgārasālāyaṁ. Atha kho vāseṭṭho upāsako yena bhagavā tenupasaṅkami; upasaṅkamitvā bhagavantaṁ abhivādetvā ekamantaṁ nisīdi. Ekamantaṁ nisinnaṁ kho vāseṭṭhaṁ upāsakaṁ bhagavā etadavoca: 

"Aṭṭhaṅgasamannāgato, vāseṭṭha, uposatho upavuttho mahapphalo hoti … pe … aninditā saggamupenti ṭhānan"ti.

2When this was said, the male lay follower Vāseṭṭha said to the Blessed One: "Bhante, if my beloved relatives and family members would observe the uposatha complete in eight factors, that would lead to their welfare and happiness for a long time. If all khattiyas would observe the uposatha complete in eight factors, that would lead to their welfare and happiness for a long time. If all brahmins … vessas … suddas would observe the uposatha complete in eight factors, that would lead to their welfare and happiness for a long time."

2Evaṁ vutte, vāseṭṭho upāsako bhagavantaṁ etadavoca:  "piyā me, bhante, ñātisālohitā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, piyānampi me assa ñātisālohitānaṁ dīgharattaṁ hitāya sukhāya. Sabbe cepi, bhante, khattiyā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, sabbesampissa khattiyānaṁ dīgharattaṁ hitāya sukhāya. Sabbe cepi, bhante, brāhmaṇā … pe … vessā … suddā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, sabbesampissa suddānaṁ dīgharattaṁ hitāya sukhāyā"ti.

3"So it is, Vāseṭṭha, so it is! If all khattiyas would observe the uposatha complete in eight factors, that would lead to their welfare and happiness for a long time. If all brahmins … vessas … suddas would observe the uposatha complete in eight factors, that would lead to their welfare and happiness for a long time. If the world with its devas, Māra, and Brahmā, this population with its ascetics and brahmins, its devas and humans, would observe the uposatha complete in eight factors, that would lead to the welfare and happiness of the world for a long time. If these great sal trees would observe the uposatha complete in eight factors, that would lead to the welfare and happiness of these great sal trees for a long time, if they could choose.[n.1715] Of the three editions, only Ee has sace ceteyyuṁ, which is consistent with the reading of the parallel at AN4.193, II 194,24–25. How much more then for a human being!"

3"Evametaṁ, vāseṭṭha, evametaṁ, vāseṭṭha. Sabbe cepi, vāseṭṭha, khattiyā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, sabbesampissa khattiyānaṁ dīgharattaṁ hitāya sukhāya. Sabbe cepi, vāseṭṭha, brāhmaṇā … pe … vessā … suddā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, sabbesampissa suddānaṁ dīgharattaṁ hitāya sukhāya. Sadevako cepi, vāseṭṭha, loko samārako sabrahmako sassamaṇabrāhmaṇī pajā sadevamanussā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, sadevakassapissa lokassa samārakassa sabrahmakassa sassamaṇabrāhmaṇiyā pajāya sadevamanussāya dīgharattaṁ hitāya sukhāya. Ime cepi, vāseṭṭha, mahāsālā aṭṭhaṅgasamannāgataṁ uposathaṁ upavaseyyuṁ, imesampissa mahāsālānaṁ dīgharattaṁ hitāya sukhāya (). Ko pana vādo manussabhūtassā"ti.

Catutthaṁ.
