In Jain Dharma, Narak (hell realms) are 7 in number, arranged in seven layers:

1. Ratnaprabha
2. Sharkaraprabha
3. Valukaprabha
4. Pankaprabha
5. Dhūmaprabha
6. Tamaprabha
7. Mahātamaprabha

Brief atmosphere of Narak

The atmosphere in Narak is extremely painful, dark, hot, and full of suffering. There is:

• intense heat and burning
• darkness or very dim light
• foul smell
• fear and misery
• constant pain caused by mutual violence and karmic suffering
• no comfort, peace, or happiness

As one goes deeper into the lower naraks, the suffering becomes more severe.

Simple understanding

Narak is not a place of eternal punishment in Jainism. It is a result of severe sinful karma, and the soul remains there until that karma is exhausted.

If you want, I can also give the names of the 7 naraks with one-line meanings in very simple Hindi or Gujarati style.
