AN 8.41 Saṅkhittūposathasutta - Uposatha In Brief

Evaṁ me sutaṁ— ekaṁ samayaṁ bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme. Tatra kho bhagavā bhikkhū āmantesi: “bhikkhavo”ti.

Thus have I heard—At one time, the Blessed One was dwelling at Sāvatthi, in Jeta’s Grove, Anāthapiṇḍika’s Park. There, the Blessed One addressed the bhikkhus: “Bhikkhus.”

“Bhadante”ti te bhikkhū bhagavato paccassosuṁ. Bhagavā etadavoca:

“Venerable sir,” those bhikkhus replied to the Blessed One. The Blessed One said this:

“Aṭṭhaṅgasamannāgato, bhikkhave, uposatho upavuttho mahapphalo hoti mahānisaṁso mahājutiko mahāvipphāro. Kathaṁ upavuttho ca, bhikkhave, aṭṭhaṅgasamannāgato uposatho mahapphalo hoti mahānisaṁso mahājutiko mahāvipphāro?

“When the Uposatha is observed endowed with the eight factors, it is of great fruit, of great benefit, superbly bright, and far-reaching. How is the Uposatha observed endowed with the eight factors, of great fruit, of great benefit, superbly bright, and far-reaching?

Idha, bhikkhave, ariyasāvako iti paṭisañcikkhati: ‘yāvajīvaṁ arahanto pāṇātipātaṁ pahāya pāṇātipātā paṭiviratā nihitadaṇḍā nihitasatthā lajjī dayāpannā, sabbapāṇabhūtahitānukampino viharanti.

Having laid aside sticks and weapons, they are conscientious, compassionate, and dwell with sympathy for the welfare of all living beings. Today, for this night and day, I too, having abandoned the killing of living beings, will abstain from killing living beings, will lay aside sticks and weapons, will be conscientious, compassionate, and dwell with sympathy for the welfare of all living beings. In this way, I shall follow the example of the arahants, and the Uposatha will be observed by me.’ Thus, one is endowed with the first factor.
