Nirvana (nibbana) literally means "blowing out" or "quenching".[41] It is the most used as well as the earliest term to describe the soteriological goal in Buddhism: release from the cycle of rebirth (saṃsāra).[42] Nirvana is part of the Third Truth on "cessation of dukkha" in the Four Noble Truths doctrine of Buddhism.[42] It is the goal of the Noble Eightfold Path.[43] The Buddha is believed in the Buddhist scholastic tradition to have realized two types of nirvana, one at enlightenment, and another at his death.[44] The first is called sopadhishesa-nirvana (nirvana with a remainder), the second parinirvana or anupadhishesa-nirvana (nirvana without remainder, or final nirvana).[44] In the Buddhist tradition, nirvana is described as the extinguishing of the fires that cause rebirths and associated suffering.[45] The Buddhist texts identify these three "three fires"[46] or "three poisons" as raga (greed, sensuality), dvesha (aversion, hate) and avidyā or moha (ignorance, delusion).[47][48] The state of nirvana is also described in Buddhism as cessation of all afflictions, cessation of all actions, cessation of rebirths and suffering that are a consequence of afflictions and actions.[42] Liberation is described as identical to anatta (anatman, non-self, lack of any self).[49][50] In Buddhism, liberation is achieved when all things and beings are understood to be with no Self.[50][51] Nirvana is also described as identical to achieving sunyata (emptiness), where there is no essence or fundamental nature in anything, and everything is empty.[52][53] In time, with the development of Buddhist doctrine, other interpretations were given, such as being an unconditioned state,[54] a fire going out for lack of fuel, abandoning weaving (vana) together of life after life,[15] and the elimination of desire.[55] However, Buddhist texts have asserted since ancient times that nirvana is more than "destruction of desire", it is "the object of the knowledge" of the Buddhist path.[56]
