The term "Hell" can be symbolic of a number of things. It may indicate a state of mind, and it may indicate an astral realm determined BY a state of mind. The thing it least likely indicates is a place down under the ground somewhere on this planet... ;-)

There are probably a great many hells, each suiting the state of mind they are dependent upon. What is hell to one might seem quite desirable to another.

Casinos, for example, strike me as hellish. So do certain bars. Other people love being there.
