What do we mean by Death to the World?
“The world” is the general name for all the passions. When we wish to call the passions by a common name, we call them the world. But when we wish to distinguish them by their special names, we call them passions. The passions are the following: love of riches, desire for possessions, bodily pleasure from which comes sexual passion, love of honor which gives rise to envy, lust for power, arrogance and pride of position, the craving to adorn oneself with luxurious clothes and vain ornaments, the itch for human glory which is a source of rancor and resentment, and physical fear. Where these passions cease to be active, there the world is dead…. Someone has said of the Saints that while alive they were dead; for though living in the flesh, they did not live for the flesh. See for which of these passions you are alive. Then you will know how far you are alive to the world, and how far you are dead to it.”
-St Isaac the Syrian (7th Century)
