The teaching in one sentence
A mendicant possessing two qualities — not guarding the doors of the senses, and eating without moderation — lives unhappily in this very life, “with distress, anguish, and fever,” and can expect a bad rebirth when the body breaks up after death.
A new book begins
This is the first discourse of the Dukanipāta, the Book of the Twos, following directly on from the Book of the Ones, which closed with Iti 27. Where that first book organized its material around single qualities — a pure mind, one act of diligence, one lie — this book pairs factors together, and this opening discourse announces that shift plainly: “when a mendicant has two qualities they live unhappily.” The two qualities named here are almost deliberately unglamorous, which is part of the point: no dramatic moral failure is required for a life to become miserable, only these two ordinary lapses, sustained.
Two lapses, not one
The two qualities are “not guarding the sense doors” (indriyesu aguttadvāratā) and “eating too much” (bhojane amattaññutā). Both belong to a stock pairing that recurs constantly through the monastic training literature, usually listed as early, foundational steps — well before deep meditative attainments are even mentioned. The point of naming them together here, rather than singly, is that they compound each other: an untrained relationship to sense experience and an untrained relationship to food together describe someone whose most basic daily contact with the world, through both eye/ear/nose/tongue/body/mind and through the simple act of eating, remains unrestrained.
“Burning in body, burning in mind”
The verse is more vivid than the prose in describing the felt result. It repeats the six sense doors by name — eye, ear, nose, tongue, body, and mind — and then states directly: “burning in body, burning in mind, by day or by night, such a person lives in suffering.” This is not suffering described as an abstract doctrinal consequence to be believed on faith; it is described as continuous, felt heat, present regardless of time of day, following directly and immediately from these two specific, correctable lapses.
Set up to be answered
This discourse does not stand alone; its very next companion, Iti 29, restates the identical structure with every term reversed — guarded senses, moderation in eating, and a happy rather than miserable life. Reading the two together makes the diagnostic purpose of this discourse clearer: it is not primarily a warning meant to stand on its own, but one half of a matched pair whose other half supplies the practical remedy in exactly parallel terms.

The text
§1This was said by the Buddha, the Perfected One: that is what I heard.
§2“Mendicants, when a mendicant has two qualities they live unhappily in this very life—with distress, anguish, and fever—and when the body breaks up, after death, they can expect a bad rebirth. What two? Not guarding the sense doors and eating too much. When a mendicant possesses these two qualities they live unhappily in this very life—with distress, anguish, and fever—and when the body breaks up, after death, they can expect a bad rebirth.”
The Buddha spoke this matter. On this it is said:
§3“Eye, ear, nose,
tongue, body, and likewise mind:
a mendicant who leaves these
sense doors unguarded—
§4immoderate in eating,
sense faculties unrestrained—
reaps suffering
both physical and mental.
§5Burning in body,
burning in mind,
by day or by night
such a person lives in suffering.”
