Just as over-drinking is a matter of habit, so too from habit comes over-sleeping. Therefore we must struggle with the question of sleep, especially in the early days of obedience, because a long-standing habit is difficult to cure.
Before all else, let us list sincere thanksgiving first on the scroll of our prayer. On the second line, we should put confession and heartfelt contrition of soul. Then let us present our petition to the King of all. This is the best way of prayer, as it was shown to one of the brethren by an angel of the Lord.
Acquire humility, which scorches the demons, obedience, which opens the door for the Son of God to enter a man, faith which saves a man, hope which makes him unashamed; and love which lets not a man fall away from God.
For the complete fulfillment of its [the intellect's] purpose we should give it nothing but the prayer 'Lord Jesus'...Those who meditate unceasingly upon this glorious and holy name in the depths of their heart can sometimes see the light of their own intellect. For when the mind is closely concentrated upon this name, then we grow fully conscious that the name is burning up all filth which covers the surface of the soul; for it is written: 'our God is a consuming fire' (Deut. 4:24). Then the Lord awakens in the soul a great love for His glory...This is the pearl of great price which a man can acquire by selling all that he has, and so experience the inexpressible joy of making it his own.
The beginning of the mortification both of the soul’s desire and of the bodily members is much hard work. The middle is sometimes laborious and sometimes not laborious. But the end is insensibility and insusceptibility to toil and pain. Only when he sees himself doing his own will does this blessed living corpse feel sorry and sick at heart; and he fears the responsibility of using his own judgment.
Until we have acquired true prayer, we are like those who introduce children to walking. Make the effort to raise up, or rather, to enclose your mind within the words of your prayer; and if, like a child, it gets tired and falters, raise it up again. The mind, after all, is naturally unstable, but the God Who can do everything can also give it firm endurance. Persevere in this, therefore, and do not grow weary...
Those pursuing the spiritual way should train themselves to hate all uncontrolled desires until this hatred becomes habitual. With regard to self-control in eating, we must never feel loathing for any kind of food, for to do so is abominable and utterly demonic. It is emphatically not because any kind of food is bad in itself that we refrain from it. But by not eating too much or too richly we can to some extent keep in check the excitable parts of our body. In addition we can give to the poor what remains over, for this is the mark of sincere love.
Let us observe and we shall find that the spiritual trumpet serves as an outward signal for the gathering of the brethren, but it is also the unseen signal for the assembly of our foes. So some of them stand by our bed, and when we get up urge us to lie down again: 'Wait,' they say, 'till the preliminary hymns are finished; then you can go to church.' Others plunge those standing at prayer into sleep. Some produce severe, unusual pains in the stomach. Others urge us on to make conversation in church. Some entice the mind to shameful thoughts. Others make us lean against the wall as though from fatigue. Sometimes they involve us in fits of yawning. Some of them bring on waves of laughter during prayer, thereby desiring to stir up the anger of God against us. Some force us to hurry the reading or chanting merely from laziness; others suggest that we should chant more slowly for the pleasure of it; and sometimes they sit at our mouths and shut them, so that we can scarcely open them. He who reckons with feeling of heart that he stands before God in prayer shall be an unshakeable pillar, and none of the aforesaid demons will make sport of him.
What is self-justification? - Self-justification is when a man denies his sin, as we see in the case of Adam, Eve, Cain and others who have sinned but, wishing to justify themselves, denied their sin.
Do not allow human respect to get in your way when you hear someone slandering his neighbor. Instead, say to him, 'Brother, stop it! I do worse things every day, so how can I criticize him?' You accomplish two things when you say this. You heal yourself and you heal your neighbor with one bandage.
Keep your mind from malicious thoughts of your neighbors, knowing that such thoughts are hurled by diabolical power, to keep your mind from your own sins and from seeking.
It is well known that obedience is the chief among the initiatory virtues, for first it displaces presumption and then it engenders humility within us. Thus it becomes, for those who willingly embrace it, a door leading to the love of God. It was because he rejected humility that Adam fell into the lowest depths of Hades. It was because He loved humility that the Lord, in accordance with the divine purpose, was obedient to his His Father even to the cross and death, although He was in no way inferior to the Father; and so through His obedience He has freed mankind from the crime of disobedience and leads back to the blessedness of eternal life all who live in obedience. Thus humility should be the first concern of those who are fighting the presumption of the devil, for as we advance it will be a sure guide to all the paths of virtue.
