In the Buddhist tradition, nirvana has commonly been interpreted as the extinction of the "three fires", or "three poisons",[note 1] greed (raga), aversion (dvesha) and ignorance (moha). When these fires are extinguished, release from the cycle of rebirth (saṃsāra) is attained.

Nirvana has also been claimed by some scholars to be identical with anatta (non-self) and sunyata (emptiness) states though this is hotly contested by other scholars and practicing monks.[web 1] In time, with the development of the Buddhist doctrine, other interpretations were given, such as the absence of the weaving (vana) of activity of the mind, the elimination of desire, and escape from the woods, cq. the five skandhas or aggregates.

Buddhist scholastic tradition identifies two types of nirvana: sopadhishesa-nirvana (nirvana with a remainder), and parinirvana or anupadhishesa-nirvana (nirvana without remainder, or final nirvana). The founder of Buddhism, the Buddha, is believed to have reached both these states.

Nirvana, or the liberation from cycles of rebirth, is the highest aim of the Theravada tradition. In the Mahayana tradition, the highest goal is Buddhahood, in which there is no abiding in nirvana. Buddha helps liberate beings from saṃsāra by teaching the Buddhist path. There is no rebirth for Buddha or people who attain nirvana. But his teachings remain in the world for a certain time as a guidance to attain nirvana.
