A new entry point, not a repeated formula
This discourse doesn't begin from old age and death, as every account in Buddhavagga did; it begins from an entirely different question — what sustains a living being — opening a new chapter with genuinely new content rather than another variation on the same starting point.
Four fuels, only one of them literally food
The list moves quickly past the most obvious sense of sustenance — edible food — to name three more abstract fuels: contact, mental intention, and consciousness itself, each maintaining beings in a different sense than nutrition does.
A question repeated four times to trace each fuel to its source
Having named the four fuels, the discourse doesn't leave them unexplained; it asks, in a fixed fourfold formula, what the source, origin, birthplace, and inception of these fuels actually is.
Two frameworks meeting at the same point
The answer to what sustains the four fuels turns out to be craving, and tracing craving's own source leads through feeling, contact, the six senses, and onward — the same twelve-link chain from Buddhavagga, now reached from an entirely different starting question.
A chapter title earned by its opening discourse
Āhāravagga takes its name directly from this discourse's central term; unlike some chapters named for an incidental detail in their closing discourse, this one is named for the concept its very first discourse introduces.
Key terms
The text
§1“Mendicants, these four fuels maintain sentient beings that have been born and help those about to be born. What four? Edible food, whether solid or subtle; contact is the second, mental intention the third, and consciousness the fourth. These are the four fuels that maintain sentient beings that have been born and help those about to be born.
§2What is the source, origin, birthplace, and inception of these four fuels? Craving. And what is the source, origin, birthplace, and inception of craving? Feeling. And what is the source of feeling? Contact. And what is the source of contact? The six sense fields. And what is the source of the six sense fields? Name and form. And what is the source of name and form? Consciousness. And what is the source of consciousness? Choices. And what is the source of choices? Ignorance.
§3And so, mendicants, ignorance is a requirement for choices. Choices are a requirement for consciousness. … That is how this entire mass of suffering originates. When ignorance fades away and ceases with no residue left behind, choices cease. When choices cease, consciousness ceases. … That is how this entire mass of suffering ceases.”
