Picture of Hell as a show
... Travel guide to the world of the dead
When someone dies with his grudges or strong emotions left in this world, he is believed to become an ogre.
If he cannot forget about his deep feelings of love and hatred to be sublimated even after he goes to the world of the dead, he turns into a ghastly apparition.
He continues to wander between the two worlds until he can pay off all scores or his desire can be fulfilled.
The ghastly apparition suddenly appears in front of those who live an easy life and frightens them or possesses and ruins them.
Ruin means death, but death does not mean the real end.
After he crosses the Styx (=dies), he starts feeling more pain in Hell.
Now, it is time to see what Hell is like.
Take this clue: why don't you travel there with a torch of the will-o'-the-wisp?
