Why this discourse

This discourse opens Āsīvisavagga ("the chapter on vipers"), this book's own nineteenth and final vagga, closing out Saḷāyatanasaṃyutta's own 248-discourse span. It is also one of the most elaborately worked allegories in this project's coverage so far: a single fleeing man is chased in succession by four venomous vipers, five armed murderers, and a sixth hidden killer, before finding an empty village raided by bandits, then a flood with no bridge or boat, which he crosses on a raft he builds himself from grass and branches. The discourse then works back through every element of the story and assigns it a precise doctrinal meaning, leaving nothing to inference: the vipers are the four elements, the murderers are the five grasping aggregates, the hidden sixth is relishing and greed, the empty village is the six interior sense fields, the bandits are the six exterior sense fields, the flood is the four floods, the near shore is substantial reality, the far shore is extinguishment, and the raft is the noble eightfold path itself.

Reading guide

Six mounting terrors, each named only as the last recedes

The narrative builds in strict sequence — four vipers, then five murderers, then a sixth hidden killer with a drawn sword — each new danger introduced only once the man is already fleeing the one before it. No single threat is ever faced in isolation; the man is always running from the whole accumulated weight of everything that has chased him so far.

An empty village that offers no refuge

Every house the man enters and every vessel he touches is “vacant, hollow, and empty” — and even this illusory refuge turns out to be under raid by bandits. The discourse later identifies the village itself as the six interior sense fields: investigated closely by “an astute, competent, clever person,” the eye, ear, nose, tongue, body, and mind each appear exactly as empty as those houses.

A raft built, not found, and released once the crossing is done

Facing a flood with no ferry or bridge, the man gathers grass, sticks, branches, and leaves and binds them into a raft himself, paddling across with his own hands and feet. The discourse's own decode names the raft the noble eightfold path and the paddling the roused energy of practice — the crossing is made, not given, and the story stops the instant the far shore is reached, without any instruction about what becomes of the raft afterward.

A complete decode, term by term, left with nothing implicit

Unlike many similes in this project's coverage that leave part of the mapping to the reader, this discourse explicitly glosses every element in turn: four vipers = the four elements; five murderers = the five grasping aggregates; the sixth hidden killer = relishing and greed; the empty village = the six interior sense fields; the bandits = the six exterior sense fields; the flood = the four floods (sensuality, desire to be reborn, views, and ignorance); the near shore = substantial reality (sakkāya); the far shore = extinguishment; the raft = the noble eightfold path; the paddling = roused energy; and the man who stands on solid ground at last = a perfected one, an arahant.

The text

The complete discourse: the six-part narrative of escalating flight and crossing, followed by the discourse's own full term-by-term decode. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1“Mendicants, suppose there were four venomous vipers of awesome might. 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. They’d say to him, ‘My friend, here are four venomous vipers of awesome might. They must be periodically picked up, washed, fed, and put to sleep. But when one or other of these four venomous vipers gets angry with you, you’ll meet with death or deadly pain. So then, my friend, do what has to be done.’

§2Then that man, terrified of those four venomous vipers, would flee this way or that. They’d say to him, ‘My friend, there are five deadly enemies chasing you, thinking: “When we catch sight of him, we’ll murder him right there!” So then, my friend, do what has to be done.’

§3Then that man, terrified of those four venomous vipers and those five deadly enemies, would flee this way or that. They’d say to him, ‘My friend, 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!” So then, my friend, do what has to be done.’

§4Then that man, terrified of those four venomous vipers and those five deadly enemies and the hidden killer, would flee this way or that. He’d see an empty village. But whatever house he enters is vacant, deserted, and empty. And whatever vessel he touches is vacant, hollow, and empty. They’d say to him, ‘My friend, there are bandits who raid villages, and they’re striking now. So then, my friend, do what has to be done.’

§5Then 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. He’d see a large deluge, whose near shore is dubious and perilous, while the far shore is a sanctuary free of peril. But there’s no ferryboat or bridge for crossing over. Then that man would think, ‘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.’

§6And so that man did exactly that. Having crossed over and gone to the far shore, the brahmin stands on solid ground.

§7I’ve made up this simile to make a point. And this is the point. ‘Four venomous vipers of awesome might’ is a term for the four principal states: the elements of earth, water, fire, and air. ‘Five deadly enemies’ is a term for the five grasping aggregates, that is: form, feeling, perception, choices, and consciousness. ‘The sixth hidden killer with a drawn sword’ is a term for relishing and greed.

§8‘Empty village’ is a term for the six interior sense fields. If an astute, competent, clever person investigates this in relation to the eye, it appears vacant, hollow, and empty. If an astute, competent, clever person investigates this in relation to the ear … nose … tongue … body … mind, it appears vacant, hollow, and empty. ‘Bandits who raid villages’ is a term for the six exterior sense fields. The eye is struck by both agreeable and disagreeable sights. The ear … nose … tongue … body … mind is struck by both agreeable and disagreeable ideas.

§9‘Large deluge’ is a term for the four floods: the floods of sensual pleasures, desire to be reborn, views, and ignorance. ‘The near shore that’s dubious and perilous’ is a term for substantial reality. ‘The far shore, a sanctuary free of peril’ is a term for extinguishment.

§10‘The raft’ is a term for the noble eightfold path, that is: right view, right purpose, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion. ‘Paddling with hands and feet’ is a term for rousing energy. ‘Crossed over, gone to the far shore, the brahmin stands on solid ground’ is a term for a perfected one.”
