If you wish to correct any one from his faults, do not think of correcting him solely by your own means: you would only do harm by your passions, for instance, by pride and by the irritability arising from it; 'but cast thy burden upon the Lord,' and pray to God, Who 'searcheth the hearts and reins,' with all your heart, that He Himself may enlighten the mind and heart of that man. If He sees that your prayer breathes love, and that it really comes from the depth of your heart, He will infallibly fulfill the desire of your heart, and you yourself will soon tell, seeing the change that has taken place in him for whom you have prayed, that it is the work of the right hand of God, the most High.
If you have Christian love for your neighbor, then all heaven will love you; if you have union of spirit with your fellow-creatures, then you shall have union with God and all the dwellers of heaven; if you are merciful to your neighbor, then God and all the angels and saints will be merciful to you; if you pray for others, then all heaven will intercede for you. The Lord our God is holy; be so yourself also.
Do not be despondent when fighting against the incorporeal enemy, but even in the midst of your afflictions and oppression praise the Lord, Who has found you worthy to suffer for Him, by struggling against the subtlety of the serpent, and to be wounded for Him at every hour; for had you not lived piously, and endeavored to become united to God, the enemy would not have attacked and tormented you.
When the flesh flourishes, the soul fades; when the flesh has full liberty, the soul is straitened; when the flesh is satiated, the soul hungers; when the flesh is adorned, the soul is deformed; when the flesh overflows with laughter, the soul is surrounded by misfortune; when the flesh is in the light, the soul is in darkness...
Reverence with all the powers of your soul all the sacraments, and say to yourself in respect to every sacrament before the celebration or the communion of it: `This is God's mystery. I myself am only the unworthy witness or partaker of it.' Otherwise our proud intellect even wishes to search out God's mystery, and, if unable to penetrate it, rejects it as not coming under the small measure of our intellect.
Our soul is simple as thought, and rapid as thought or lightning. In an instant it can be wounded by sin and become attached to corruptible things; in an instant it can fall away from the love of God and its neighbor through a single unrighteous thought, through a single passionate desire, through a single malevolent thought, and, therefore, we must constantly watch our heart, lest it should incline to words or thoughts of evil, and must ever strive to preserve it in God's simplicity and purity, and in the love of God and its neighbor.
The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavours to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness.
The evil spirit tries to scatter prayer as if it were a sand heap, tries to turn the words into dry sand, without coherency or moisture - that is to say, without fervor of heart. Thus prayer may become either a house built on sand or a house built on a rock. Those build on sand who pray without faith, absently, coldly: such prayer is scattered of itself, and does not bring any profit to him who prays; those build on a rock who, during the whole time of their prayer, have their eyes fixed upon God, and pray to Him as to a living person, conversing face to face with them.
Most men not only bear Satan's burden willingly in their hearts, but they become so accustomed to it that they often do not feel it, and even imperceptibly increase it. Sometimes, however, the evil enemy increases his burden tenfold, and then they become terribly despondent and fainthearted, they murmur and blaspheme God's name. The usual means that men... take to drive away their anguish are... entertainments... But such means afterwards increase still more the anguish and weariness of their hearts. If, happily, they turn to God, then the burden is removed from their heart, and they clearly see that previously the heaviest burden was lying on their heart, though frequently they did not feel it.
The candles lit before the icons of the Theotokos are a symbol of the fact that She is the Mother of the Unapproachable Light, and also of Her most pure and burning love for God and Her love for mankind.
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.
Imagine, picture the multitude of your sins and imagine how tolerant of them is the Master of your life, while you are unwilling to forgive your neighbor even the smallest offense. Moan and bewail your foolishness, and that obstruction within you will vanish like smoke, you will think more clearly, your heart will grow calm, and through this you will learn goodness, as if not you yourself had heard the reproaches and indignities, but some other person entirely, or a shadow of yourself.
Keep a strict watch against any appearance of pride: it appears imperceptibly, particularly in time of vexation and irritability against others for quite unimportant causes.
We ought to have the most lively spiritual union with the heavenly inhabitants, with all the saints, apostles, prophets, martyrs, prelates, venerable and righteous men, as they are all members of one single body, The Church of Christ, to which we sinners also belong, and the living Head of which is the Lord Jesus Christ Himself. This is why we call upon them in prayer, converse with them, thank and praise them, It is urgently necessary for all Christians to be in union with them, if they desire to make Christian progress; for the saints are our friends, our guides to salvation, who pray and intercede for us.
The Church is the sure way to the life eternal; walk in it undeviatingly, hold fast to it, and you will gain the kingdom of heaven; but if you turn aside at the crossways of your own sophistry and unbelief, then you have only yourself to blame, you will go astray and be lost. ‘I am the way, the truth, and the life.’ (John 14:6)
