When you intend to do something and see that your thought is perturbed, and if after invoking God's Name it remains perturbed even by a hair's breadth, know from this that the action you mean to commit is from the evil one and refrain from commiting it. For nothing done with perturbation is pleasing to God.
Prayer demands that the mind should be pure of all thought and should admit nothing not belonging to prayer, even if it were good in itself. As if inspired by God the mind should withdraw from all things and hold its converse with Him alone.
When our Lord Jesus Christ at the Mystical Supper conversed with His disciples, having warned them at the end of His talk with the words, In the world ye shall have tribulation, He then concluded with the words, But stand firm: I have overcome the world. The Apostle and Evangelist John the Theologian in one of his epistles in a certain way continued the words expressed by his Divine Teacher by writing, This is the victory that overcometh the world - our faith. Therefore the Orthodox Church on the first Sunday of Great Lent celebrates the Triumph of Orthodoxy, the Church celebrates her victory, the victory of the Orthodox Faith over all false teachings, over persecutions and oppression, that great multitude of which she experienced in her bright but sorrowful path.
To act 'according to one’s strength' means to use a little less than necessary both of food, and drink, and sleep... As for food, restrain yourself when you wish to eat a little more, and in this way you will always make use of it moderately.
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.
Angels are a light for monks, and the monastic life is a light for all men. Therefore let monks strive to become a good example in everything, giving no occasion for stumbling in anything (II Corinthians 6:3) in all their works and words. For if the light becomes darkness, how much darker will be that darkness, that is, those living in the world.
In these days of vacillation, confusion of thought and corruption, we confess the true teaching of the Church regardless of the opinions held by those who might hear us and disregarding the skepticism and faithlessness of our environment. If, for the sake of conforming to the errors of the times, we would suppress the truth or yet profess distorted doctrines to please the world, we would in fact be offering stones instead of bread. And the higher the position of one who would act in this way, the more profound the temptation and the more serious the consequences.
If a person swallows too much food, he is inviting impure thoughts. If he mortifies the stomach, he is creating pure thoughts. Often a lion if it is caressed becomes domesticated, whereas the more you coddle the body, the more it goes wild.
It seems to me that few people understand the extent of the cunning wickedness of these demons and the way in which they assist one another. I have known the demon of cowardice to fight and work together with that of listlessness. One comes to the aid of the other and reinforces him. The first brings fear and obduracy into the soul, the second produces darkness, negligence, blindness of heart and mind, and finally despair. Listlessness is a real trial for all those engaged in the spiritual struggle, but it becomes for them the ambassador of humility.
The incessant invocation of God's name is a medicine which mortifies not just the passions, but even their influence. Just as the physician puts medications or dressings on a wound that it might be healed, without the patient even knowing the manner of their operation, so also the name of God, when we invoke it, mortifies all passions, though we do not know how that happens.
