If you find yourself hating your fellow men and resist this hatred, and you see that it grows weak and withdraws, do not rejoice in your heart; for this withdrawal is a trick of the evil spirits. They are preparing a second attack worse than the first; they have left their troops behind the city and ordered them to remain there. If you go out to attack them, they will flee before you in weakness. But if your heart is then elated because you have driven them away, and you leave the city, some of them will attack you from the rear while the rest will stand their ground in front of you; and your wretched soul will be caught between them with no means of escape. The city is prayer. Resistance is rebuttal through Christ Jesus…. The Philokalia: St Isaiah the Solitary verse II
