One of the saints said : ‘ If you wish to bear malice, bear malice against the demons, and if you wish to be hostile, be always hostile to the body. The flesh is a deceitful friend, and when pampered rises against you all the more.’ And: ‘ Bear enmity to the body and wage war against the belly.’
St. Hesychius of Jerusalem; On Sobriety and Prayer
The intellect cannot conquer a demonic fantasy by its own unaided powers, and should never attempt to do so.
The demons are a sly lot: they pretend to be overcome and then trip us up by filling us with self-esteem. But when we call upon Jesus Christ, they do not dare to play their tricks with us even for a second.
St. Hesychios the Presbyter, On Watchfulness and Holiness
It is the task of unceasing watchfulness – and one of great benefit and help to the soul – to see the mental images of evil thoughts as soon as they are formed in the mind. The task of rebuttal is to counter and expose such thoughts when they attempt to infiltrate our mind in the form of an image of some material thing. What instantly extinguishes and destroys every demonic concept, thought, fantasy, illusion and idol is the invocation of the Lord. And in our mind we ourselves can observe how our great God, Jesus, triumphs over them all, and how He avenges us, poor, base and useless as we are.
St. Hesychios the Presbyter, on watchfulness and holiness, Philokalia
We have learned from experience that for one who wishes to purify his heart it is a truly great blessing constantly to invoke the name of the Lord Jesus Christ against his intelligible enemies.
Notice how what I speak of from experience concurs with the testimony of Scripture. It is written: ‘Prepare yourself, O Israel, to call upon the name of the Lord your God’ (cf. Amos 4:12. lxx);and the Apostle says: ‘Pray without ceasing’ ( 1 Thess. 5:17). Our Lord Himself says: ‘Without Me you can do nothing. If a man dwells in Me, and I in him, then he brings forth much fruit’; and again: ‘If a man does not dwell in Me, he is cast out as a branch’ (John 15:5–6). Prayer is a great blessing, and it embraces all blessings, for it purifies the heart, in which God is seen by the believer.
St. Hesychios the Presbyter, Philokalia, #173
The more the rain falls on the earth the softer it makes it;
similarly, Christ’s holy name gladdens theearth of our heart the
more we call upon it.
St Hesychius the Priest, On Watchfulness and Holiness, #41
Those who love true knowledge should also be aware that the demons in their jealousy sometimes hide themselves and cease from open spiritual battle. Begrudging us the benefit, knowledge and progress towards God that we derive from the battle, they try to make us careless so that they can suddenly capture our intellect and again reduce our mind to inattention. Their unremitting purpose is to prevent the heart from being attentive, for they know how greatly such attentiveness enriches the soul. We on the contrary, through remembrance of our Lord Jesus Christ, should redouble our efforts to achieve spiritual contemplation; and then the intellect again finds itself engaged in battle. Let all we do be done with great humility and only, if I may put it like this, with the will of the Lord Himself. St. Hesychios the Presbyter, On Watchfulness and Holiness
