In Buddhism , the chain of causation that leads from rebirth to death.
Existence is seen as an interrelated flux of transient events that occur in a series, one producing another, usually described as a chain of 12 links: (1) ignorance, which leads to (2) faulty perceptions of reality, which provide the structure of (3) knowledge, which addresses (4) name and form, or the principle of individual identity and the sensory perception of an object, experienced through (5) the six domains (the five senses and their object, along with the mind), whose presence leads to (6) contact (between objects and the senses), followed by (7) sensation, which, being pleasant, leads to (8) thirst and then (9) grasping (as of sex partners), which leads to (10) the process of becoming, culminating in (11) birth, and at last (12) old age and death.
