Naraka is a concept found in various Indian religions, including Hinduism, Buddhism, and Jainism. It is often described as a realm of suffering or hell where souls experience punishment for their negative actions in life. The duration and nature of suffering in Naraka can vary based on the severity of one's misdeeds. In Buddhism, Naraka is not considered eternal; instead, it is a temporary state where beings can be reborn after serving their time. The teachings emphasize the importance of karma, suggesting that one's actions directly influence their experiences in Naraka and future lives.
