In ancient Sanskrit, the three syllables (Nir+Va+Na) each have meanings themselves, so when combined they can be translated in different ways such as, 'To be free from entangled roots' or ' To escape the woven web'.
'Nirvana' or 'Nibbana' is explained as the goal that is attained by those who follow the path of Buddhism, a long spiritual journey of meditation and harnessing good karma. The literal meaning of the term nirvana is translated as 'blowing out', or 'quenching'. Nirvana is described as the ultimate spiritual goal in Buddhism, to mark the release from the cycle of rebirth, or 'Samsara'.
In Buddhist traditions, nirvana is explained as the extinction or removal of the 'three fire's'. Passion or 'Raga', aversion or 'Dvesha', and ignorance or 'Moha'. Only once these fires have been spiritually snuffed out you are said to attain a state of nirvana. It describes a state of removal from the cycle of rebirth and suffering but different traditions in Buddhism have interpreted it in different ways.
There are two different stages in the philosophy of nirvana, one in life and another in death. The former is said to be imprecise and general while the latter is precise and specific. Nirvana in life marks an individual who has attained the complete release from desire and suffering while maintaining a body, name, and life. Nirvana after death is the complete cessation of everything including consciousness and rebirth.
The Pali word 'Nibbana' and Sanskrit word 'Nirvana' is believed to be first said by The Buddha to describe the highest state of well-being a human is capable of achieving, where the mind becomes consciously awake from delusions, liberated from bondage, cleansed of defilements, and becomes entirely at peace.
In-depth, nirvana is about understanding and reaching a mental state beyond the four noble truths.
The four noble truths are principles that surround the nature of life, which states the essence of Buddha's teachings. The truth of suffering (Dukkha), the truth of the origin of suffering (Samudaya), the truth of the cessation of suffering (Nirodha), and the truth of the path to the cessation of suffering (Magga).
According to the Buddhist view, when ordinary people die and their physical bodies disintegrate, each person's unresolved karma passes on to new birth and thus karmic inheritance is reborn. However, when a person achieves the state of nirvana they are liberated from the cycle of rebirth or moksha.
