Saṁyutta Nikāya 56.31 4.

Thus have I heard.

Sīsapāvanavagga Sīsapāvanasutta Ekaṁ samayaṁ bhagavā kosambiyaṁ viharati sīsapāvane.

At one time, the Blessed One was dwelling in the Sīsapā forest near Kosambi.

Atha kho bhagavā parittāni sīsapāpaṇṇāni pāṇinā gahetvā bhikkhū āmantesi: “Taṁ kiṁ maññatha, bhikkhave, katamaṁ nu kho bahutaraṁ— yāni vā mayā parittāni sīsapāpaṇṇāni pāṇinā gahitāni yadidaṁ upari sīsapāvane”ti?

Then the Blessed One took a few sīsapā leaves in his hand and addressed the disciples: What do you think which is more numerous, the few sīsapā leaves in my hand or those in the forest above?

“Appamattakāni, bhante, bhagavatā parittāni sīsapāpaṇṇāni pāṇinā gahitāni; atha kho etāneva bahutarāni yadidaṁ upari sīsapāvane”ti.

Venerable Sir, the few sīsapā leaves in the Blessed One's hand are very few, while those in the forest above are far more numerous.

“Evameva kho, bhikkhave, etadeva bahutaraṁ yaṁ vo mayā abhiññāya anakkhātaṁ.

Just so what I have directly known but not taught is far more.

Kasmā cetaṁ, bhikkhave, mayā anakkhātaṁ?

And why have I not taught it?

Na hetaṁ, bhikkhave, atthasaṁhitaṁ nādibrahmacariyakaṁ na nibbidāya na virāgāya na nirodhāya na upasamāya na abhiññāya na sambodhāya na nibbānāya saṁvattati; tasmā taṁ mayā anakkhātaṁ.

Because it is not connected with the goal, does not lead to the holy life, to disenchantment, to dispassion, to cessation, to peace, to direct knowing, to enlightenment, to Nibbāna.

Therefore, I have not taught it.

Kiñca, bhikkhave, mayā akkhātaṁ?

And what have I taught?

‘Idaṁ dukkhan’ti, bhikkhave, mayā akkhātaṁ, ‘ayaṁ dukkhasamudayo’ti mayā akkhātaṁ, ‘ayaṁ dukkhanirodho’ti mayā akkhātaṁ, ‘ayaṁ dukkhanirodhagāminī paṭipadā’ti mayā akkhātaṁ.

This is suffering I have taught. This is the origin of suffering, I have taught. This is the cessation of suffering, I have taught. This is the path leading to the cessation of suffering, I have taught.

Kasmā cetaṁ, bhikkhave, mayā akkhātaṁ?

And why have I taught this?

Etañhi, bhikkhave, atthasaṁhitaṁ etaṁ ādibrahmacariyakaṁ etaṁ nibbidāya virāgāya nirodhāya upasamāya abhiññāya sambodhāya nibbānāya saṁvattati; tasmā taṁ mayā akkhātaṁ.

Because it is connected with the goal, leads to the holy life, to disenchantment, to dispassion, to cessation, to peace, to direct knowing, to enlightenment, to Nibbāna.

Tasmātiha, bhikkhave, ‘idaṁ dukkhan’ti yogo karaṇīyo …pe…

Therefore, I have taught it.

Therefore This suffering is to be known...

‘ayaṁ dukkhanirodhagāminī paṭipadā’ti yogo karaṇīyo”ti. Paṭhamaṁ.

This is the path leading to the cessation of suffering is to be developed.
