In Jain cosmology, there are seven levels of hell (Naraka) in the lower world (Adho Loka). These are:

1) Ratna-prabha 2) Sharkara-prabha 3) Valuka-prabha 4) Panka-prabha 5) Dhum-prabha 6) Tamaḥ-prabha 7) Mahā-tamaḥ-prabha

Souls go to these hells due to their negative karma, and their stay is finite (not eternal). The order and names are generally agreed across Śvetāmbara and Digambara traditions, though some texts may vary slightly in details or naming.
