“The best way to defeat the devil is by patience. As long as we endure and do not take revenge, the spirit of peace calms us. To the degree that we pray for our enemies and take all the blame on ourselves, we will feel great peace in our souls. And if our thoughts tell us that “so-and-so is also to blame and not just me,” and this thought conquers us, then the Holy Spirit leaves us, we begin to feel heaviness in our souls, and we can’t endure anymore.”
(Elder Proclu+ of Romania in pravoslavie.ru)
