In Jainism, "Naraki" refers to the beings who reside in Naraka, which is a realm of existence characterized by suffering and is often translated as "hell" in English. According to Jain cosmology, souls are reborn in Naraka as a result of the accumulation of extremely negative karma, particularly from acts involving violence, deceit, and other harmful behaviors.

A Naraki, or a being in Naraka, does not die in the conventional sense. Instead, beings in Naraka have a fixed lifespan that is determined by the amount and type of karma that led them there. They must endure their suffering for the duration of their lifespan, which can be extremely long, depending on the depth of their karmic bondage.

Once the lifespan in Naraka is completed, the soul leaves that body and is reborn in another realm according to its remaining karma. This could be as a human, an animal, a celestial being, or again in Naraka, depending on the karmic balance.

Jainism emphasizes that no external deity causes the suffering in Naraka; it is purely the result of one's own actions (karma). Liberation (moksha) is only possible when all karmas are destroyed, which cannot happen while in Naraka. Only after the Naraki's lifespan ends and the soul is reborn in a different realm can it pursue spiritual progress.

In summary: A Naraki "dies" when its predetermined lifespan in Naraka is over, after which the soul leaves that realm and is reborn elsewhere, in accordance with its remaining karma.
