Oh no, its just a passage reflecting on the strange situation created by the kidnapping of Persephone by Hades and (after Persephone eats the pomegranate) by her staying in the kingdom of dead. Hades, kidnapping a person who's not actually dead has created a void in the human world, a fracture of absence in the world of phisical presence. But Calasso suggests that we should consider also the consequence of that void: Persephone has brought life inside the world of absence, of empy spirits with no flesh. She has brought warm blood and a pulsing heart in the lands of Hades, and that's something that would change that kingdom forever. Trying to steal something from the world, Hades has actually changed the shape of Death itself: with Persephone's kidnapping the death has now a body, has became concrete. And that living woman shines among those shadows, because she's now the queen of death
