According to Google's web definition, "hell" is based on an old Anglo Saxon word meaning "to cover". In later English usage hell came to mean the underworld, and even later still, a fiery place beneath the surface of the earth.
The late Pope John Paul wrote in the Vatican newspaper, Osservatore Romano, that hell is not a geographical location. This angered many Christian groups. He responded in a second article by saying that heaven isn't a geographical location either, but rather the state of being in the presence of God. The failure to repent for sins prevents humankind from reaching that state of bliss.
I recently read a interview of a professor of religious studies at Magill University in Montreal, a Sikh (can't remember his name at the moment). He explained that for Sikhs heaven is on earth (assuming we have connected with the Guru). I am not sure if there is a Sikh equivalent for "hell" . It would be interesting if someone in the forum could speak to that.
