Nirvana (Sanskrit, also ‘nirvana’ ) is the earliest and most common term used to describe the goal of the Buddhist path. The term is ambiguous, and has several meanings.The literal meaning is "blowing out" or "quenching." Within the Buddhist tradition, this term has commonly been interpreted as the extinction of the "three fires", or "three poisons",passion , aversion and ignorance or. When these fires are extinguished, release from the cycle of rebirth is attained.In time, with the development of 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, the five skandhas or aggregates.Buddhist tradition distinguishesbetween nirvana in this lifetime and nirvana after death. In "nirvana-in-this-lifetime" physical life continues, but with a state of mind that is free from negative mental states, peaceful, happy, and non-reactive. With "nirvana-after-death", paranirvana, the last remains of physical life vanish, and no further rebirth takes place.Nirvana 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, but a Buddha re-enters the world to work for the salvation of all sentient beings.Although "non-self" and "impermanence" are accepted doctrines within most Buddhist schools, the teachings on nirvana reflect a strand of thought in which nirvana is seen as a transcendental, "deathless" realm, in which there is no time and no "re-death." This strand of thought may reflect pre-Buddhist influences, and has survived especially in Mahayana-Buddhism and the idea of the Buddha Nature.The term nirvana describes a state of freedom from suffering and rebirth, but its meaning is ambiguous, and several interpretations are possible. The origin is probably pre-Buddhist, and its etymology may not be conclusive for its meaning. The term was a more or less central concept among the Jains, the Ajivikas, the Buddhists, and certain Hindu strands, and it may have been imported into Buddhism with much of its semantic range from other sramanic movements It has a wide range of meanings, although the literal meaning is "blowing out" or "quenching". It refers both to the act and the effect of blowing (at something) to put it out, but also the process and outcome of burning out, becoming extinguished.
