This is strange. Explaining stuff to myself.

Hum.
Something new to me that Buddhists and Hindus believe in hell.
Can you please tell me where you got this information from?  

That was news to me, too. But then I found this:

Naraka (Sanskrit: नरक) is the Sanskrit word for the underworld; literally, of man. According to some schools of Hinduism, Sikhism, Jainism and Buddhism, Naraka is a place of torment, or Hell. The word 'Neraka' (modification of Naraka) in Indonesian and Malaysian has also been used to describe the Islamic concept of Hell.

So . . . yeah. There are so many strands of Hinduism and Buddhism, I suppose some ideas -- such as Naraka being in some sense a place or state of torment in the afterlife -- might have gained currency among some believers. But I certainly don't recall Buddha, for example, being said to have talked about this. And the idea seems to fly in the face of Karma/reincarnation.

Considering the enormous area over which Buddhism, especially, spread, it's not really that surprising, I suppose. It's probably not much different than Western religions spreading over a wide area and absorbing local beliefs/customs along the way. The absorbed ideas might not be accepted as orthodox, but they may become a part of some communities' approach to the "mother faith" into which they are absorbed.

In Bali most people follow a degenerate form of Hinduism.
By the way Hinduism is also a degenerate form of yoga so if we go down and down in the degeneration process we can see devils and hell just like we can see in the Balinese culture but if we go the opposite way toward the original philosophy there is no place for devils and hell that is why we should be very careful before we judge just by looking at some degenerative forms of the original one.
