At this point the zealous man looks inward, and what do you think he finds there? Ceaseless wandering of thoughts, constant onslaughts from the passions, hardness and coldness of heart, obstinacy and disobedience, desire to do everything according to his own will. In a word, he finds everything within himself in a very bad state. And seeing this, his zeal is inflamed, and he now directs strenuous efforts to the development of his inner life, to controlling his thoughts and the dispositions of his heart. From directions on inner spiritual life he discovers the necessity of paying attention to oneself, of watching over the movements of the heart. In order not to admit to anything bad, it is necessary to preserve the remembrance of God. And so he sets to work to achieve this remembrance. But his thoughts can no more be arrested than the wind; his bad feelings and worthless impulses can no more be evaded than the stench of a corpse; his mind, like a wet and frozen bird, cannot rise to the remembrance of God. What is to be done? Be patient, they say, and go on working. Patience and labor are exercised, but all within remains the same. At last someone of experience is found who explains that all is inwardly in disorder because the forces within are divided: mind and heart each go their own way. Mind and heart must be united; then wandering of thoughts will cease, and you will gain a rudder to steer the ship of your soul, a lever by which to set in movement all your inner world. But how can one unite mind and heart? Acquire the habit of praying these words with the mind in the heart, 'Lord Jesus Christ, Son of God, have mercy upon me'. And this prayer, when you learn to perform it properly, or rather when it becomes grafted to the heart, will lead you to the end which you desire. It will unite your mind with your heart, it will cut off your wandering thoughts, and give you the power to govern the movements of your soul.
Fear is a rehearsing of danger beforehand; or again, fear is a trembling sensation of the heart, alarmed and troubled by unknown misfortunes. Fear is a loss of assurance.
Our prayer reflects our attitude towards God. He who is careless of salvation has a different attitude toward God from him who has abandoned sin and is zealous for virtue but has not yet entered within himself and works for the Lord only outwardly. Finally, he who has entered within and carries the Lord within himself, standing before Him, has yet another attitude. The first man is negligent in prayer, just as he is negligent in life, and he prays in church and at home merely according to the established custom, without attention or feeling. The second man reads many prayers and goes often to church, trying at the same time to keep his attention from wandering and to experience feelings in accordance with the prayers which are read, although he is seldom successful. The third man, wholly concentrated within, stands with his mind before God, and prays to Him in his heart without distraction, without long verbal prayers, even when standing for a long time at prayer in his home or in church.... Every prayer must come from the heart and any other prayer is no prayer at all. Prayer-book prayers, your own prayers and very short prayers, all must issue forth from the heart to God, seen before you.
When we stand in prayer, those unclean and unspeakable thoughts (blasphemy) assail us; but if we continue praying to the end, they retire at once, for they do not fight those who stand up to them.
Set as a goal the kindling of the fire of the spirit, so that the spiritual fire will burn in your heart and, gathering up all your strength into one, will begin to build your inner man and finally burn up the tares of your sins and passions.
The Lord often humbles the vainglorious by causing some dishonor to befall them. And indeed the first step in overcoming vainglory is to remain silent and to accept dishonor gladly. The middle stage is to check every act of vainglory while it is still in thought. The end—insofar as one may talk of an end to an abyss—is to be able to accept humiliation before others without actually feeling it.
If it is a mark of extreme meekness, even in the presence of one’s offender, to be peacefully and lovingly disposed towards him in one’s heart, then it is certainly a mark of hot temper when a person continues to quarrel and rage against his offender, both by words and gestures, even when by himself.
There is no shorter ascent to the royal and Divine mansions...than through subduing the five passions hostile to obedience, namely: disobedience, argumentativeness, self-gratification, self-justification and pernicious high opinion of oneself...Disobedience is the mouth of hell; argumentativeness its tongue, whetted like a sword; self-gratification is its sharp teeth; self-justification its throat; high opinion of oneself, which casts one into hell, is the belching of its all-devouring belly. But he who, through obedience, conquers the first, by one stroke cuts off all the rest and with one stride reaches heaven.
As long as the flesh is in full health, let us observe abstinence at all times and in every place. When it has been tamed (which I do not suppose is possible this side of the grave), then let us hide our accomplishment.
The Lord says: 'In your patience possess ye your souls' (Luke 21:19). He did not say: in your fast or in your vigil. By patience I mean that patience which is of God and is the queen of virtues and the basis of manly valor. It is in itself - peace amid strife, stillness in the midst of storm and an impregnable position for those who have acquired it.
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.
