I was a part of a controversial (and extremely popular) sect of Buddhism a few years ago. Their idea of hell was similar to the Divine Comedy where there are multiple levels and rings of Narok (Thai pronunciation).

The punishments carried out in each level reflect the crime committed. E.g. Harm and murder of living things such as animals or other humans are punished by the person being brutally murdered only to instantly reincarnate and be murdered all over again and again.

My "favorite" is the adultery level which the punishable male is "endowed" with a very long (several meters), sharp, burning, metallic penis that is perpetually in pain from the flames. Women that are being punished are then skewered and impaired by males metal flaming phallus from her vagina through her body and out her throat, forming a human torture kabab between the two which intertwine them in perpetual pain and suffering.
