Dependent origination

Dependent origination (Sanskrit pratītyasamutpāda, "arising in dependence") is one of the most central and characteristic teachings of Buddhism, found in its oldest layer and accepted across every later school. Its core is a single principle: nothing arises on its own. Every event, feeling, and thing comes into being only because of supporting conditions, and passes away when those conditions cease. There are no truly independent, self-standing items in experience — only an interdependent flow.

The early teaching most often presents this as a twelve-link chain showing how suffering is built up, step by step: (1) basic ignorance of how things really are gives rise to (2) volitional formations, our karma-laden mental dispositions, which condition (3) consciousness, which conditions (4) "name-and-form," the mind-body organism, which conditions (5) the six sense-bases, which condition (6) contact with objects, which conditions (7) feeling (pleasant, painful, or neutral), which conditions (8) craving, which conditions (9) clinging, which conditions (10) becoming, which conditions (11) birth, which conditions (12) aging-and-death — and with them the whole mass of suffering. Read in reverse it is liberating: remove ignorance and craving, and the chain that produces suffering comes apart.

The teaching is also the philosophical engine behind much later Buddhist thought. If everything exists only in dependence on conditions, then nothing has a fixed, independent essence of its own — and from this the Mahāyāna idea of "emptiness" was drawn. Dependent origination is meant less as a creation story than as a precise diagnosis of how, moment by moment, we build the very experience we then suffer.
