In Jain belief, Narak (hell) is a realm where beings suffer as a result of their negative karmas. Key points:

• Purpose: Narak is not eternal punishment; it is a temporary state in the cycle of birth and death (samsara) that helps the soul pay off the karmic debt it has accumulated.
• Causes: The suffering arises because of bad actions in past lives—harsh speech, violence, deceit, harming others, cruelty, and other immoral deeds.
• Types and torments: There are various forms of suffering in Narak, designed to fit the specific karmic load of the being. Common descriptions include extreme heat or cold, physical torture, hunger, thirst, and being tormented by demons or painful environments. The exact distinctions and details vary in different Jain traditions.
• Duration: The duration of stay in Narak depends on the amount of negative karma one has accumulated. Once that karma is exhausted, the soul can be reborn again in another realm (human, animal, or other loka), according to the remaining karmas.
• Spiritual aim: The Jain path emphasizes purifying the mind, speech, and actions to avoid creating new karmas and to gradually burn off past karmas, leading to a liberation (moksha) from the cycle of birth and death.

Difference between Digambar and Shwetambar descriptions: Both traditions acknowledge Narak and its purpose, but there can be variations in the enumeration of specific hells and the details of punishments. The core idea—that suffering in Narak is temporary and tied to karmic results, not eternal damnation—remains consistent.
