Nirvana is a word from the Buddhist context, which means the state of liberation of the soul attained by the human being as he goes through his search for the spiritual path.
The term originates in Sanskrit, and can be translated as "extinction" in the sense of "cessation of suffering".
It is one of the fundamental themes of Buddhist doctrine. In a broader sense, Nirvana indicates an eternal state of grace and is also seen by some as a way of overcoming karma.
