Pratītyasamutpāda

Pratītyasamutpāda (Sanskrit; Pāli: paṭiccasamuppāda), often translated as dependent origination or dependent arising, is a fundamental doctrine across all Buddhist schools. It holds that every conditioned phenomenon comes into being only in relation to other phenomena. The core idea is summed up in the formula: when this exists, that exists; when this ceases, that ceases. In short, all conditioned things—whether events, objects, or principles—arise because other things are present.

The doctrine covers both the forward process that leads to suffering (anuloma-paṭiccasamuppāda) and the reverse process that ends it (paṭiloma-paṭiccasamuppāda). These are laid out in various lists of dependently originated phenomena, the most famous being the twelve links, or nidānas (dvādasanidānāni in Pāli and Sanskrit). Traditionally, these lists are interpreted as describing how a sentient being is reborn in saṃsāra and experiences suffering, all without needing to assume an unchanging self or eternal soul. Reversing the chain is said to bring about the cessation of rebirth and, with it, the end of suffering.

Another interpretation sees the lists as mapping how mental processes give rise to a sense of “I” and “mine,” which then leads to grasping and suffering. Some modern Western scholars point to inconsistencies in the twelve-link list and argue it is a later synthesis of older elements, some traceable to the Vedas.

The doctrine appears throughout early Buddhist texts. It is the main subject of the Nidāna Saṃyutta in the Theravada school’s Saṃyutta Nikāya (SN), and a parallel collection exists in the Chinese Saṃyukta Āgama (SA).

**Overview**

Dependent origination is philosophically complex and has many explanations, which often focus on different aspects and are not necessarily contradictory. It differs from classic Western causation, where one thing’s action directly causes a change in another. Instead, change is seen as arising from many factors, not just one or a few.

As an ontological principle—a concept about existence—it holds that all phenomena come from pre-existing phenomena, and current phenomena condition future ones. Everything in the world has causes. This is closely tied to the Buddhist doctrine of rebirth, explaining how rebirth occurs without a fixed self, as a process conditioned by various relations.

As an epistemological principle—a theory about knowledge—it asserts that nothing is permanent or stable, though some permanent phenomena exist, such as space (vacuum), cessations (including nirvana), and suchness (the absence of self, anatta). Because everything is dependently originated, nothing is permanent (anicca) and nothing has an essence (anatta). This is closely linked to the doctrine of emptiness (śūnyatā).

As a phenomenological or psychological principle, it refers to how the mind works—how suffering, craving, and the view of a self arise. This can describe how mental states condition each other over time or how different mental phenomena condition each other in a single moment.

**Etymology**

Pratītyasamutpāda combines two terms. *Pratītya* means “having depended.” It appears in the Vedas and Upanishads with senses like confirmation, dependence, and acknowledging origin. Its root *prati* appears widely in Vedic literature, meaning to go toward, go back, or approach, with connotations of observing, learning, convincing oneself of truth, believing, or recognizing. A related term *pratiti* means going toward, approaching, or insight into anything.

*Samutpāda* means “arising,” “rise,” “production,” or “origin.” In Vedic literature, it means to spring up together, arise, occur, effect, form, produce, or originate.

English translations include dependent origination, dependent arising, interdependent co-arising, conditioned arising, and conditioned genesis. Jeffrey Hopkins notes that synonyms include *apekṣasamutpāda* and *prāpyasamutpāda*.

The term can also refer to the twelve nidānas (Pāli: *dvādasanidānāni*, Sanskrit: *dvādaśanidānāni*), from *dvādaśa* (“twelve”) and *nidānāni* (plural of “nidāna,” meaning cause, motivation, or link). In the Mahayana tradition, *pratityasamutpada* (Sanskrit) generally refers to the broad principle of interdependent causation, while in the Theravada tradition, *paticcasamuppāda* (Pāli) usually refers specifically to the twelve nidānas.

**Dependent origination in early Buddhism**

In early Buddhist texts, the principle of conditionality is called by various names, such as the certainty or law of dhamma (*dhammaniyāmatā*), suchness of dharma (*dharmatathatā*), the enduring principle (*ṭhitā dhātu*), specific conditionality (*idappaccayatā*), and dhammic nature (*dhammatā*). It is expressed in its most general form as: when this exists, that exists; when this ceases, that ceases.
