Provide yourself with such work for your hands as can be done, if possible, both during the day and at night, so that you are not a burden to anyone, and indeed can give to others, as St. Paul the Apostle advises (cf. I Thess. 2:9; Eph. 4:28). In this manner you will overcome the demon of listlessness and drive away all the desires suggested by the enemy; for the demon of listlessness takes advantage of idleness. 'Every idle man is full of desires' (Prov. 13:4 LXX).
Evagrius PonticusIf your spirit still looks around at the time of prayer, then it does not yet pray as a monk. You are no better than a man of affairs engaged in a kind of landscape gardening.
Evagrius PonticusHe who has mastery over his incensive power has mastery also over the demons. But anyone who is a slave to it is a stranger to the ways of the Saviour, for as the Saviour enjoined us: 'Learn from Me; for I am gentle and humble in heart: and you will find rest for your souls' (Mt. 11:29). Now if a man abstains from food and drink, but becomes incensed to wrath because of evil thoughts, he is like a ship sailing the open sea with a demon for a pilot.
Evagrius PonticusRemember how the Lord rebukes Martha when He says: 'You are anxious and troubled about many things: one thing alone is needful' (Lk. 10:41-42) ? to hear the divine word; after that, one should be content with anything that comes to hand.
