The book starts off with Father Amorth once again discussing the prominent theme of his previous book which is, the rising need of exorcisms due to "Western consumerism." He holds that the inadequate supply of exorcists is largely due to theological errors which are taught in seminaries.
There is plenty of redundant material, such as content relating to the angels, Satan’s fall and role as prince of all creation, the six categories of Satan’s extraordinary activity (as opposed to ordinary, or temptation), the four principle causes of possession, and once again the methodology for priests performing exorcisms.
The most interesting and unique part of the book is actually its discussion on the “nefarious influence of certain music.” Amorth points out that music of evil influence abides by 4 principles: beat, volume intensity, ritual consecration of every record during a black mass. Here is his elaboration of the first principle:
“Beat. The first important item is the rhythm, called beat, which mimics the sexual act. Abruptly, the listeners are caught up in a frenzy designed to produce a sort of hysteria. It is the result of the sexual instinct, which is aroused through the use of beat.”
He goes on to deconstruct the psychological impact of the other nefarious principles in eye-opening fashion. His explanation is excellent at peeling back a layer of self-deception that so many people have regarding popular music.
This book was made because of the tremendous reaction and attention that was given to the first book. They loaded the book with detailed accounts of possessions that each illustrate a certain purpose. These accounts are the most engaging parts of the book, while the rest is either methodology for would-be exorcists, or Catholic teaching on demonology for orthodox Catholics.
