“…the leading demons are eight in number, which are as many as the deadly passions: gluttony, lust, avarice, despondency, anger, slothfulness, vainglory and pride. Each evil spirit wars against us and operates in their own way, depending on the passion they support. However, all the demons work together to immerse us in the deepest possible way in the passions and to make us slaves to sin, in order to separate us from God and lead us to eternal death…”
