Train yourself to cut off an intrusive thought immediately…Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
People, until they come to know something greater, are satisfied with the little that they have. Man is like a village rooster who lives in a small enclosure with few people and farm animals about, who knows his ten hens and is content with this life, because he knows no more. But an eagle, who circles high in the clouds, and sees great distances with his sharp eyes, who hears the sounds of the earth and revels in its beauty, who knows many lands, seas and rivers, and sees a multitude of
animals and birds, would not be content to live in a small enclosure with a rooster. It is the same in spiritual life. Whoever has not known the grace of the Holy Spirit is like the rooster who does not know the flight of the eagle; he cannot comprehend the sweetness of tender emotion and love of God. He knows God from nature and from Scripture, he is satisfied with the law and is content with his lot as is the rooster, and does not feel sorrow that he is not an eagle. But he who has experienced the Lord through the Holy Spirit, he prays day and night, because the grace of the Holy Spirit calls him to love the Lord, and the sweetness of the Lord's love gives him the ability to carry the burdens of the world with ease; his soul pines only for the Lord and searches constantly for the grace of the Holy Spirit.
Obedience is necessary not only for monks, but for all people. Even the Lord was obedient. Proud and self-assured do not let grace reside within them, and therefore they never have internal peace, whereas the soul of the obedient easily accepts the grace of the Holy Spirit, bringing with it joy and serenity.
The man who does not humble himself and does not cleanse his heart from evil desires fasts in vain. He may eat nothing at all, but it will be to no avail if there is evil inside him. He must first cleanse himself from the evil within in order to receive the Lord.
The Saints in Heaven through the Holy Spirit behold the glory of God and the beauty of the Lord's Countenance. But in this same Holy Spirit they see our lives too, and our deeds. They know our sorrows and hear our burning prayers. When they were living on earth they learned of the love of God from the Holy Spirit: and he who knows love on earth takes it with him into eternal life in the Kingdom of Heaven, where love grows and becomes perfect. And if love makes one unable to forget a brother here, how much more must the Saints remember and pray for us!
Any soul which has lost its peace must repent, and the Lord will forgive its sins, and then peace and joy will visit the soul. There need be no witnesses, for the Holy Spirit is the witness of the remission of sins. Here is a sign of forgiveness: if you have come to hate sin, then the Lord has forgiven your sin.
The evil one cannot comprehend the joy we receive from the spiritual life; for this reason he is jealous of us, he envies us and sets traps for us, and we become grieved and fall. We must struggle, because without struggles we do not obtain virtues.
The good man thinks to himself in this wise: Every one who has strayed from the truth brings destruction on himself and is therefore to be pitied. But of course the man who has not learned the love of the Holy Spirit will not pray for his enemies. The man who has learned love from the Holy Spirit sorrows all his life over those who are not saved, and sheds abundant tears for the people, and the grace of God gives him strength to love his enemies.
Whoever repents sincerely is prepared to withstand any sorrow: hunger and homelessness, cold and heat, illness and poverty, humiliation and banishment, lies and slander, for the soul seeks God and does not concern itself with anything worldly, but instead prays with a clear mind.
During the time of one’s confession not only the person who makes his confession is judged, but the confessor as well. In the past, confessors were practical. They did not judge on the basis of the seriousness of a transgression, but rather on the intent. They did not concentrate so much on the sins being confessed as on thinking of how to treat the repentant person’s soul.
Dr. George Bebis writes that 'In one of his letters, St. Basil [the Great] explicitly writes that he accepts the intercession of the apostles, prophets and martyrs, and he seeks their prayers to God. (Letter 360) Then, speaking about the Forty Martyrs, who suffered martyrdom for Christ, he emphasizes that they are common friends of the human race, strong ambassadors and collaborators in fervent prayers. (Chapter 8) St. Gregory of Nyssa asks St. Theodore the Martyr... to fervently pray to our Common King, our God, for the country and the people (Encomium to Martyr Theodore).'
One time St. Nicodemos, on a feast day, was walking toward the Great Lavra (on Mt Athos). On his way he came across a kellion where he spent the night. At midnight he saw an elder and his accompanying monks entering the church. He secretly went in also, and there he saw the elder and his subordinate monks uttering the Jesus Prayer ('Lord Jesus Christ, Son of God, have mercy on me'), sometimes in a kneeling position, sometimes standing up. And at the time of the Holy Communion, he saw all their faces shining only a little less dimly than the sun.
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.
The Saints were people just like ourselves. Many of them started with grievous sins but through repentance they attained the Kingdom of Heaven. And every one who comes to the Kingdom of Heaven does so through repentance which the Merciful Lord granted us by His sufferings. In the Kingdom of Heaven, the holy Saints look upon the glory of our Lord Jesus Christ; but through the Holy Spirit they see, too, the sufferings of men on earth. The Lord gave them such great grace that they embrace the whole world with their love. They see and know how we languish in affliction, how our hearts have withered within us, how despondency has fettered our souls, and they never cease to intercede for us to God.
Paissy the Great, having lost his temper, begged the Lord to deliver him from irritability. The Lord appeared to him and said, ‘Paissy, if thou dost not wish to get angry, desire nothing, neither criticize nor hate any man, and thou wilt have no anger.’
