Bodily listlessness and torpor, which affect the soul as a result of our laziness and negligence, not only make us abandon our normal rule of prayer, but also darken the mind and fill it with despondency. Then blasphemous and cowardly thoughts arise in the heart. Indeed, the person tempted by the demon of listlessness cannot even enter his usual place of prayer; he grows sluggish, and absurd thoughts directed against the Creator of all things arise in his mind. Aware of the cause of all this and why it has happened to you, resolutely enter your normal place of prayer and, falling down before the God of love, ask with a compunctive and aching heart, full of tears, to be freed from the weight of listlessness and from your pernicious thoughts. If you knock hard and insistently, this release will soon be given to you.
~St Symeon the New Theologian
