The teaching in one sentence
Eight mendicants each describe developing mindfulness of death by imagining a progressively shorter remaining lifespan — from a full day and night down to the time it takes to breathe out after breathing in — and the Buddha judges only the final two, the single mouthful and the single breath, as genuinely diligent practice; the other six, however sincerely meant, he calls negligent.
Eight confessions, each shorter than the last
One mendicant after another volunteers their own practice: wishing to live another day and night, then a day, then half a day, then the time to eat an almsmeal, then half an almsmeal, then four or five mouthfuls, then a single mouthful, then finally a single breath — each reciting the identical framing, that with this much time they could focus on the Buddha's instructions and achieve a great deal.
A sharp verdict, not an equal validation
Rather than praising all eight mendicants equally for their sincerity, the Buddha draws a clear line: the six who measure their urgency in days, half-days, or meals are called negligent, living carelessly, developing mindfulness of death only slackly — only the two who measure it in a single mouthful or a single breath are called diligent.
Urgency measured in breaths, not days
The discourse's real teaching lies in where it draws this line: even wishing for a full day and night of remaining life, which sounds urgent by ordinary standards, is judged insufficiently urgent here. Only awareness pitched to the scale of a single mouthful or breath meets the Buddha's own standard for genuine diligence.

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?”

§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 for half a 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 single almsmeal, 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 half an almsmeal, 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
§3When this was said, the Buddha said to those mendicants: “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 for half 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 eat half 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 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.”
