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.
The designation of a Christian consists in glorifying the Heavenly Father by one's life. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven (Matt. 5:16). But true glorification of God is possible only if one rightly believes and expresses his right belief in words and deeds.
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.
Do not judge one another, for you transgress the evangelical law, and 'every transgression and disobedience received a just retribution' (Heb. 2:2). 'Who are you to pass judgment on the servant of another?' (Rom. 14:4). Do you not know that the one who passes judgment goes astray through pride, and that everyone who exalts himself will be humbled (Luke 14:11) by the Lord, when temptation seizes him?
In his concern for the salvation of souls, a pastor must remember that people also have physical needs which cry out for attention. One mustn’t preach the Gospel without showing love in action. At the same time, caution must be observed lest solicitude in meeting the physical needs of his neighbor swallow up the pastor’s attention altogether and serve to detract from his spiritual concerns. He must bear in mind the Apostle’s words: 'It is not reason that we should leave the word of God, and serve tables' (Acts 6:2). Everything must be directed towards acquiring the Kingdom of God and fulfilling Christ’s Gospel. True Christianity does not consist in intellectual abstract deliberations and teachings; rather, it is incarnate in life itself. Christ descended to earth not to instruct people in new forms of knowledge, but to call them to a new life. During our earthly life we prepare ourselves for eternity. The various circumstances and events of temporal life act to influence a man’s spiritual life. Those with strong characters are able to surmount the influence of their surroundings, while the weak give in to it. The strong in spirit are tempered by persecutions, while the weak fall. It is therefore necessary, insofar as possible, to create conditions in which as many people as possible can be spiritually formed.
Therefore silence, prayer, obedience; when you practice these virtues with the help of God, then you will know the light of Christ is within your soul.
If you wish to be delivered from shameful passions, do not behave with anyone familiarly, especially with those toward whom your heart is inclined by a lustful passion; through this you will be delivered also from vainglory. For in vainglory is involved the pleasing of men, in the pleasing of men is involved familiarity of behavior, and familiarity of behavior is the mother of all passions.
My brother, the passions are afflictions; and so the Lord does not excommunicate us because of them, but He says: 'Call upon me in the time of affliction; and I will deliver thee, and thou shalt glorify me'. Therefore, when beset by any kind of passion, there is nothing more useful than to call upon the Name of God. All we can do, weak as we are, is to flee for refuge to the Name of Jesus. For the passions, being demons, retreat if this Name is invoked.
If something pushes you to criticism about some business or other of a brother or of a monastery, you, rather, try to pray about the matter, without passing it under judgment of your reason.
Give thanks to God for all things, because thanksgiving is intercession before God for our weakness. Judge yourself always and in everything as a sinner and as one seduced - and so God will not judge you; be humble in everything and you will receive grace.

Concerning fasting, do not grieve, as I have said to you before: God does not demand of anyone labors beyond his strength. And indeed, what is fasting if not a punishment of the body in order to humble a healthy body and make it infirm for passions, according to the word of the Apostle: 'When I am weak, then am I strong' (II Corinthians 12:10).
At your work, flee conversation; only measured words in case of need. The hands should work for the needs of the body, and the mind should say the sweetest name of Christ, so that the need of the soul, which we must not forget even for moment, also will be provided for.

Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
