Isaac of Nineveh for Lent VIII

When we wish to give a collective name to the passions, we call them world. And when we wish to designate them specifically according to their names, we call them passions. the passions are portions of the course of the world's onward flow; and where the passions cease, there the world's onward flow stands still. These are the passions: love of wealth; gathering objects of any kind; bodily pleasure, from which comes the passion of carnal intercourse; love of esteem, from which springs envy; the wielding of power; pride in the trappings of authority; stateliness and pomposity; human glory, which is the cause of resentment; fear for the body. Wherever these have halted in their course, there, in part, to the extent that the passions are inactive, the world fails from its constitution and remains inactive. Thus it was with each of the saints, that while they lived, they were dead. For living in the body, they lived not according to the flesh.
