What is nibbana (nirvana)? Is it nothingness, emptiness, or something else?

Nibbāna (Sanskrit nirvāṇa) is the complete fading away and abandoning of craving, and with it of suffering (dukkha) and of renewed becoming. It is not non-existence, and not a trance. It should not be confused with emptiness either: in the early texts emptiness (suññatā) means that phenomena are empty of “I” and “mine” (SN 35.85, MN 121), while the base of nothingness (ākiñcaññāyatana) is a separate meditative attainment, itself conditioned (MN 140).

Nibbāna is the third of the Four Noble Truths (MN 141) and the final goal of the Noble Eightfold Path - final liberation from ignorance and from that same craving (for sense pleasures, for becoming and for non-becoming), going beyond saṃsāric existence and conditionality.

The word means “going out and cooling down” - the way a fire goes out when its fuel runs out. SN 43.12 defines the unconditioned (asaṅkhata) as the state in which passion (rāga), aversion (dosa) and delusion (moha) are completely destroyed. This is not a temporary calm in which these states simply do not show up, but their final uprooting.

The suttas give nibbāna many epithets, both negative and positive: the unborn, unbecome, unmade, unconditioned (Ud 8.3), the deathless (amata), the highest happiness, peace, the island (dīpa), the shelter (leṇa), the refuge (saraṇa) - a long list is collected in SN 43.14-43. These are epithets, not an exact definition. It cannot truly be compared with anything we know, because ordinary experiences arise thanks to conditions and then pass away. Even deep meditative concentration is conditioned and impermanent, unlike the “unconditioned” nibbāna. That is why it cannot be described precisely in words, and the Buddha preferred to speak about the Path rather than about Awakening itself.

The canon distinguishes two elements of nibbāna (Iti 44). “With residue” (saupādisesa) is the liberation of an arahant while alive: craving is exhausted, but the five sense faculties are intact, and they still experience the pleasant and the painful. “Without residue” (anupādisesa) is the final going out at the arahant’s death: there is no new birth, and the conditioned process of experience is no longer fed by anything and does not start up again. The word parinibbāna usually points to the second case, as in the account of the Buddha’s passing (DN 16), though in the early texts it is not always kept strictly apart from plain “nibbāna”.

Hence the usual worry: does all this amount to annihilation? When Vacchagotta asked whether a Tathāgata exists after death, the Buddha replied that none of the four alternatives applies (he exists, he does not exist, both, neither), and compared it to a fire: once a fire has gone out for lack of fuel, asking which direction it went is meaningless (MN 72). The Buddha does not say that the Tathāgata simply vanished - he sets aside a wrongly posed question.

Nibbāna is not an object that can be obtained, not a place one can arrive at, not an analogue of paradise and not the annihilation of the person, but the end of identifying with the illusion of an unchanging “I” and going beyond conceptual structures, an unconditioned state of mind reached when all defilements are uprooted.

The canon does not invite speculation about nibbāna. The Buddha compared the going out to an oil lamp that burns while oil and wick last and goes out when they are gone (MN 140), and described the liberated person’s knowledge in a dry formula repeated across the canon: birth is ended, the holy life has been lived, what had to be done has been done, there will be no more new becoming.
