The teaching in one sentence
Immediately after stating the twelve-fold formula of dependent origination, the Buddha defines every single link in precise, technical terms — not to add anything new to the chain, but to make sure no one is left guessing what any given link actually refers to.
A glossary, not a new teaching
The sutta opens exactly where the bare formula does: “Mendicants, I will teach and analyze for you dependent origination,” followed by the familiar twelve-step chain running from ignorance to “this entire mass of suffering.” What is distinctive is what happens next. Rather than moving on, the Buddha turns around and asks, of each link in turn, “And what is …?” — working backward this time, starting with old age and death and ending with ignorance, before restating the whole chain forward and in reverse one final time. The effect is of a teacher who has just given a formula and now insists on defining every term in it before anyone is allowed to walk away with a vague impression of what it means.
The twelve links, defined
Each definition is brief, but exact. Read together, they form a kind of technical dictionary for the entire chain:
| Link | The Buddha’s definition |
|---|---|
| Old age and death | The physical deterioration of a being (grey hair, broken teeth, failing faculties) and, separately, the breaking up of the aggregates and laying to rest of the corpse |
| Rebirth | The various beings’ coming to be, being born, conceived, and acquiring the aggregates and sense fields |
| Continued existence | The three realms of existence: sensual, form, and formless |
| Grasping | Four kinds: grasping at sensual pleasures, at views, at precepts and observances, and at a theory of a self |
| Craving | Six classes, for sights, sounds, smells, tastes, touches, and ideas |
| Feeling | Six classes, born of contact through each of the six senses |
| Contact | Six classes, through each of the six senses |
| The six sense fields | The internal sense bases of eye, ear, nose, tongue, body, and mind |
| Name and form | Name = feeling, perception, intention, contact, and application of mind; form = the four principal states and form derived from them |
| Consciousness | Six classes: eye, ear, nose, tongue, body, and mind consciousness |
| Choices | Three kinds: bodily, verbal, and mental choices |
| Ignorance | Not knowing the four noble truths — suffering, its origin, its cessation, and the path to its cessation |
Notice how consistently the definitions lean on enumeration rather than description: almost every link turns out to be “six classes of” something tied to the six senses, or a short, closed list (three kinds of choices, four kinds of grasping, three realms of existence). This is part of what makes the sutta function as a reference text rather than a piece of reflective teaching — it is built to be looked up, not merely read once.
Why the reverse order is not an accident
After stating the chain forward, the Buddha defines the links starting from the end (old age and death) and moving back toward the beginning (ignorance), only restating the forward order in the closing recap. This mirrors the investigative logic found elsewhere in the tradition, including in this same curated selection: one starts from the suffering that is obviously present — aging, death, sorrow — and asks what it depends on, then asks what that depends on, and so on, rather than starting from an abstraction like “ignorance” and working forward as if it were simply a list to memorize. The order of exposition, in other words, retraces the order of discovery.
What this definitional pass rules out
Several of the definitions quietly foreclose common misreadings. “Consciousness” is not defined as a single continuous stream or a unified faculty but as six distinct classes, one per sense door, arising each time a sense makes contact with its object — there is no thirteenth, unifying observer consciousness added to the list. “Name and form” likewise resolves into a specific, analytic list of mental factors (feeling, perception, intention, contact, attention) plus the four principal states and what is derived from them, rather than standing in for anything as vague as “body and mind” in general. And “ignorance” is defined with surgical precision as not knowing the four noble truths specifically — not as a general lack of intelligence or worldly knowledge, but as a specific gap in understanding of exactly those four things.
How this discourse gets used
Because it is so exact and so compact, this sutta is frequently cited on its own, independent of any particular narrative context, whenever a later discussion needs to pin down what one of the twelve links means. A discourse describing dependent origination operating in some particular case — as with the investigation of “mind” elsewhere in this curated selection — can be read with much more precision once these definitions are in view, since the terms it uses (feeling, craving, grasping, contact) are no longer placeholders but have a fixed, technical sense established here.
Key terms
The text
The setting and the bare formula
§1At Sāvatthī. “Mendicants, I will teach and analyze for you dependent origination. Listen and apply your mind well, I will speak.” “Yes, sir,” they replied. The Buddha said this:
§2“And what is dependent origination? Ignorance is a requirement for choices. Choices are a requirement for consciousness. Consciousness is a requirement for name and form. Name and form are requirements for the six sense fields. The six sense fields are requirements for contact. Contact is a requirement for feeling. Feeling is a requirement for craving. Craving is a requirement for grasping. Grasping is a requirement for continued existence. Continued existence is a requirement for rebirth. Rebirth is a requirement for old age and death, sorrow, lamentation, pain, sadness, and distress to come to be. That is how this entire mass of suffering originates.
Old age and death, and rebirth
§3And what is old age and death? The old age, decrepitude, broken teeth, grey hair, wrinkly skin, diminished vitality, and failing faculties of the various sentient beings in the various orders of sentient beings. This is called old age. The passing away, passing on, disintegration, demise, mortality, death, decease, breaking up of the aggregates, and laying to rest of the corpse of the various sentient beings in the various orders of sentient beings. This is called death. Such is old age, and such is death. This is called old age and death.
§4And what is rebirth? The rebirth, inception, conception, regeneration, manifestation of the aggregates, and acquisition of the sense fields of the various sentient beings in the various orders of sentient beings. This is called rebirth.
Continued existence and grasping
§5And what is continued existence? There are these three states of existence. Existence in the sensual realm, the realm of luminous form, and the formless realm. This is called continued existence.
§6And what is grasping? There are these four kinds of grasping. Grasping at sensual pleasures, views, precepts and observances, and theories of a self. This is called grasping.
Craving and feeling
§7And what is craving? There are these six classes of craving. Craving for sights, sounds, smells, tastes, touches, and ideas. This is called craving.
§8And what is feeling? There are these six classes of feeling. Feeling born of contact through the eye, ear, nose, tongue, body, and mind. This is called feeling.
Contact and the six sense fields
§9And what is contact? There are these six classes of contact. Contact through the eye, ear, nose, tongue, body, and mind. This is called contact.
§10And what are the six sense fields? The sense fields of the eye, ear, nose, tongue, body, and mind. These are called the six sense fields.
Name and form, and consciousness
§11And what are name and form? Feeling, perception, intention, contact, and application of mind. This is called name. The four principal states, and form derived from the four principal states. This is called form. Such is name and such is form. These are called name and form.
§12And what is consciousness? There are these six classes of consciousness. Eye, ear, nose, tongue, body, and mind consciousness. This is called consciousness.
Choices and ignorance
§13And what are choices? There are three kinds of choices. Choices by way of body, speech, and mind. These are called choices.
§14And what is ignorance? Not knowing about suffering, the origin of suffering, the cessation of suffering, and the practice that leads to the cessation of suffering. This is called ignorance.
The chain restated
§15And so, 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.”
