The teaching in one sentence
Of seven mendicants who each report developing mindfulness of death by reflecting on how much they could accomplish if they had only some short remaining span of life, the Buddha calls the five who named a day and night down to a few mouthfuls negligent, and only the two who named a single mouthful or a single breath diligent.
A single practice, tested at shrinking scales
Every one of the seven answers follows the identical form: “Oh, if I'd only live for …, I'd focus on the Buddha's instructions and I could really achieve a lot.” What varies is only the assumed remaining span — a day and night, a day, a meal, four or five mouthfuls, one mouthful, one breath. The discourse does not ask mendicants to imagine different content; it asks how short a span they are willing to take seriously as possibly their last.
Where the Buddha draws the line, and why
The cutoff falls between “four or five mouthfuls” and “a single mouthful” — a distinction that might look arbitrary stated baldly, but the discourse's own logic is about the interval between successive checks. A mendicant who only reflects on death across the span of an entire meal has, within that meal, many moments where the reflection has gone stale; one who reflects at the scale of a single mouthful, or a single breath, is renewing the reflection continuously enough that negligence has no room to creep in between checks.
Negligence, not the content of the reflection, is being judged
It would be a misreading to conclude the Buddha is dismissing the first five mendicants' sincerity or effort. He does not question whether they meant what they said; the discourse explicitly names their practice “slack” (pamattā) rather than false or insincere. The distinction drawn is about rigor of application, not honesty of intention.
Setting up AN 6.20's fuller method
This discourse names a criterion — frequency of renewal — without describing what a mendicant actually reflects on beyond the bare formula of wishing for more time. AN 6.20, immediately following and sharing this discourse's setting at Ñātika, supplies that fuller content: a nightly and daily checklist of specific causes of death and unabandoned unskillful qualities, with its own simile of urgency, clothes or head on fire.

The text
At Ñātika: the Buddha's question
§1At one time the Buddha was staying at Ñātika in the brick house. There the Buddha addressed the mendicants, “Mendicants!” “Venerable sir,” they replied. The Buddha said this: “Mendicants, when mindfulness of death is developed and cultivated it’s very fruitful and beneficial. It has freedom from death as its objective and culmination. But do you develop mindfulness of death?”
Seven mendicants answer in turn
§2When he said this, one of the mendicants said to the Buddha, “Sir, I develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live for another day and night, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.” Another mendicant said to the Buddha, “Sir, I too develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live for another day, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.” Another mendicant said to the Buddha, “Sir, I too develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live as long as it takes to eat a meal of almsfood, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.” Another mendicant said to the Buddha, “Sir, I too develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live as long as it takes to chew and swallow four or five mouthfuls, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.” Another mendicant said to the Buddha, “Sir, I too develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live as long as it takes to chew and swallow a single mouthful, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.” Another mendicant said to the Buddha, “Sir, I too develop mindfulness of death.” “But mendicant, how do you develop it?” “In this case, sir, I think: ‘Oh, if I’d only live as long as it takes to breathe out after breathing in, or to breathe in after breathing out, I’d focus on the Buddha’s instructions and I could really achieve a lot.’ That’s how I develop mindfulness of death.”
The Buddha's verdict: negligent and diligent
§3When this was said, the Buddha said to those mendicants: “As to the mendicants who develop mindfulness of death by wishing to live for a day and night … or to live for a day … or to live as long as it takes to eat a meal of almsfood … or to live as long as it takes to chew and swallow four or five mouthfuls—these are called mendicants who live negligently. They slackly develop mindfulness of death for the ending of defilements. But as to the mendicants who develop mindfulness of death by wishing to live as long as it takes to chew and swallow a single mouthful … or to live as long as it takes to breathe out after breathing in, or to breathe in after breathing out—these are called mendicants who live diligently. They keenly develop mindfulness of death for the ending of defilements. So you should train like this: ‘We will live diligently. We will keenly develop mindfulness of death for the ending of defilements.’ That’s how you should train.”
