The Buddha teaches on the six sense bases regarding the simile of the vipers, guiding disciples toward discernment of sense experience and release from clinging.

SN 35.238 The Simile of the Vipers

“Seyyathāpi, bhikkhave, cattāro āsīvisā uggatejā ghoravisā. Atha puriso āgaccheyya jīvitukāmo amaritukāmo sukhakāmo dukkhappaṭikūlo.

Tamenaṁ evaṁ vadeyyuṁ: ‘ime te, ambho purisa, cattāro āsīvisā uggatejā ghoravisā kālena kālaṁ vuṭṭhāpetabbā, kālena kālaṁ nhāpetabbā, kālena kālaṁ bhojetabbā, kālena kālaṁ saṁvesetabbā.

Atha kho so, bhikkhave, puriso bhīto catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ yena tena palāyetha.

Tamenaṁ evaṁ vadeyyuṁ: ‘ime kho, ambho purisa, pañca vadhakā paccatthikā piṭṭhito piṭṭhito anubandhā, yattheva naṁ passissāma tattheva jīvitā voropessāmāti. Yaṁ te, ambho purisa, karaṇīyaṁ taṁ karohī’ti.

“Seyyathāpi, bhikkhave, cattāro āsīvisā uggatejā ghoravisā.

“Mendicants, suppose there were four venomous vipers of awesome might.

Atha puriso āgaccheyya jīvitukāmo amaritukāmo sukhakāmo dukkhappaṭikūlo.

Then a person would come along who wants to live and doesn’t want to die, who wants to be happy and recoils from pain.

Tamenaṁ evaṁ vadeyyuṁ:

They’d say to him,

‘ime te, ambho purisa, cattāro āsīvisā uggatejā ghoravisā kālena kālaṁ vuṭṭhāpetabbā, kālena kālaṁ nhāpetabbā, kālena kālaṁ bhojetabbā, kālena kālaṁ saṁvesetabbā.

‘My man, here are four venomous vipers of awesome might. They must be periodically picked up, washed, fed, and put to sleep.

Yadā ca kho te, ambho purisa, imesaṁ catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ aññataro aññataro kuppissati, tato tvaṁ, ambho purisa, maraṇaṁ nigacchasi, maraṇamattaṁ dukkhaṁ.

But when one or other of these four venomous vipers gets angry with you, you’ll meet with death or deadly pain.

Yaṁ te, ambho purisa, karaṇīyaṁ taṁ karohī’ti.

So then, my man, do what has to be done.’

Atha kho so, bhikkhave, puriso bhīto catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ yena tena palāyetha.

Then that man, terrified of those four venomous vipers, would flee this way or that.

Tamenaṁ evaṁ vadeyyuṁ:

They’d say to him,

‘ime kho, ambho purisa, pañca vadhakā paccatthikā piṭṭhito piṭṭhito anubandhā, yattheva naṁ passissāma tattheva jīvitā voropessāmāti.

‘My man, there are five deadly enemies chasing you, thinking: “When we catch sight of him, we’ll murder him right there!”

Yaṁ te, ambho purisa, karaṇīyaṁ taṁ karohī’ti.

So then, my man, do what has to be done.’

Atha kho so, bhikkhave, puriso bhīto catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ, bhīto pañcannaṁ vadhakānaṁ paccatthikānaṁ yena tena palāyetha.

Then that man, terrified of those four venomous vipers and those five deadly enemies, would flee this way or that.

Tamenaṁ evaṁ vadeyyuṁ:

They’d say to him,

‘ayaṁ te, ambho purisa, chaṭṭho antaracaro vadhako ukkhittāsiko piṭṭhito piṭṭhito anubandho yattheva naṁ passissāmi tattheva siro pātessāmīti.

‘My man, there’s a sixth hidden killer chasing you with a drawn sword, thinking: “When I catch sight of him, I’ll chop off his head right there!”

Yaṁ te, ambho purisa, karaṇīyaṁ taṁ karohī’ti.

So then, my man, do what has to be done.’

Atha kho so, bhikkhave, puriso bhīto catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ, bhīto pañcannaṁ vadhakānaṁ paccatthikānaṁ, bhīto chaṭṭhassa antaracarassa vadhakassa ukkhittāsikassa yena tena palāyetha.

Then that man, terrified of those four venomous vipers and those five deadly enemies and the hidden killer, would flee this way or that.

So passeyya suññaṁ gāmaṁ.

He’d see an empty village.

Yaññadeva gharaṁ paviseyya rittakaññeva paviseyya tucchakaññeva paviseyya suññakaññeva paviseyya.

But whatever house he enters is vacant, deserted, and empty.

Yaññadeva bhājanaṁ parimaseyya rittakaññeva parimaseyya tucchakaññeva parimaseyya suññakaññeva parimaseyya.

And whatever vessel he touches is vacant, hollow, and empty.

Tamenaṁ evaṁ vadeyyuṁ:

They’d say to him,

‘idāni, ambho purisa, imaṁ suññaṁ gāmaṁ corā gāmaghātakā pavisanti.

‘My man, there are bandits who raid villages, and they’re striking now.

Yaṁ te, ambho purisa, karaṇīyaṁ taṁ karohī’ti.

So then, my man, do what has to be done.’

Atha kho so, bhikkhave, puriso bhīto catunnaṁ āsīvisānaṁ uggatejānaṁ ghoravisānaṁ, bhīto pañcannaṁ vadhakānaṁ paccatthikānaṁ, bhīto chaṭṭhassa antaracarassa vadhakassa ukkhittāsikassa, bhīto corānaṁ gāmaghātakānaṁ yena tena palāyetha.

Then that man, terrified of those four venomous vipers and those five deadly enemies and the hidden killer and the bandits, would flee this way or that.

So passeyya mahantaṁ udakaṇṇavaṁ orimaṁ tīraṁ sāsaṅkaṁ sappaṭibhayaṁ, pārimaṁ tīraṁ khemaṁ appaṭibhayaṁ.

He’d see a large deluge, whose near shore is dubious and perilous, while the far shore is a sanctuary free of peril.

Na cassa nāvā santāraṇī uttarasetu apārā pāraṁ gamanāya.

But there’s no ferryboat or bridge for crossing over.

Atha kho, bhikkhave, tassa purisassa evamassa:

Then that man would think,

‘ayaṁ kho mahāudakaṇṇavo orimaṁ tīraṁ sāsaṅkaṁ sappaṭibhayaṁ, pārimaṁ tīraṁ khemaṁ appaṭibhayaṁ, natthi ca nāvā santāraṇī uttarasetu apārā pāraṁ gamanāya.

Yannūnāhaṁ tiṇakaṭṭhasākhāpalāsaṁ saṅkaḍḍhitvā kullaṁ bandhitvā taṁ kullaṁ nissāya hatthehi ca pādehi ca vāyamamāno sotthinā pāraṁ gaccheyyan’ti.

‘Why don’t I gather grass, sticks, branches, and leaves and make a raft? Riding on the raft, and paddling with my hands and feet, I can safely reach the far shore.’

Atha kho so, bhikkhave, puriso tiṇakaṭṭhasākhāpalāsaṁ saṅkaḍḍhitvā kullaṁ bandhitvā taṁ kullaṁ nissāya hatthehi ca pādehi ca vāyamamāno sotthinā pāraṁ gaccheyya, tiṇṇo pāraṅgato thale tiṭṭhati brāhmaṇo.

And so that man did exactly that. Having crossed over and gone to the far shore, the brahmin stands on solid ground.

Upamā kho myāyaṁ, bhikkhave, katā atthassa viññāpanāya.

I’ve made up this simile to make a point.
