Upavānasutta

Pabbatavagga Upavānasutta Ekaṁ samayaṁ āyasmā ca upavāno āyasmā ca sāriputto kosambiyaṁ viharanti ghositārāme.

At one time, the venerable Upavāna and the venerable Sāriputta were dwelling in Kosambi, in the Ghositārāma.

Atha kho āyasmā sāriputto sāyanhasamayaṁ paṭisallānā vuṭṭhito yenāyasmā upavāno tenupasaṅkami; upasaṅkamitvā āyasmatā upavānena saddhiṁ sammodi.

Then, the venerable Sāriputta, having emerged from seclusion in the evening, approached the venerable Upavāna; having approached, he exchanged greetings with the venerable Upavāna.

Sammodanīyaṁ kathaṁ sāraṇīyaṁ vītisāretvā ekamantaṁ nisīdi.

After exchanging pleasant and meaningful greetings, he sat down to one side.

Ekamantaṁ nisinno kho āyasmā sāriputto āyasmantaṁ upavānaṁ etadavoca: “Jāneyya nu kho, āvuso upavāna, bhikkhu ‘paccattaṁ yonisomanasikārā evaṁ susamāraddhā me satta bojjhaṅgā phāsuvihārāya saṁvattantī’”ti?

Seated to one side, the venerable Sāriputta said to the venerable Upavāna: Friend Upavāna, would a disciple know through attention directed at the origin internally, thus my seven factors of enlightenment are well developed for easeful dwelling?

“Jāneyya kho, āvuso sāriputta, bhikkhu ‘paccattaṁ yonisomanasikārā evaṁ susamāraddhā me satta bojjhaṅgā phāsuvihārāya saṁvattantī’”ti.

Friend Upavāna, a disciple would know through attention directed at the origin internally, thus my seven factors of enlightenment are well developed for easeful dwelling.

“Satisambojjhaṅgaṁ kho, āvuso, bhikkhu ārabbhamāno pajānāti ‘cittañca me suvimuttaṁ, thinamiddhañca me susamūhataṁ, uddhaccakukkuccañca me suppaṭivinītaṁ, āraddhañca me vīriyaṁ, aṭṭhiṁ katvā manasi karomi, no ca līnan’ti …pe…

Friend, starting with the factor of mindfulness enlightenment, a disciple knows my mind is well liberated, my sloth and torpor are well dispelled, my restlessness and remorse are well calmed, my energy is aroused, I am resolute in mind, not lax …
