Habit forms from custom, and habit seems to accustom itself to nature. It is much worse and more difficult to change nature. However, with God it is possible. For nature does not set itself against God.
It is pointless for someone to say that he has faith in God if he does not have works which go with faith. What benefit were their lamps to the foolish virgins who had no oil (Matt. 25: 1-13), namely, deeds of love and compassion?
Fasting was ordained in Paradise. The first injunction was delivered to Adam, ‘Of the tree of the knowledge of good and evil you shall not eat.’ ‘You shall not eat’ is a law of fasting and abstinence. The general argument is rather against excess than in support of ceremonial abstinence. In Paradise there was no wine, no butchery of beasts, no eating of flesh. Wine came in after the flood. Noah became drunk because wine was new to him. So fasting is older than drunkenness. Esau was defiled, and made his brother’s slave, for the sake of a single meal. It was fasting and prayer which gave Samuel to Hannah. Fasting brought forth Samson. Fasting begets prophets, strengthens strong men. Fasting makes lawgivers wise, is the soul’s safeguard, the body’s trusty comrade, the armor of the champion, the training of the athlete.
The Spirit is not united to the soul by drawing near to its place (for how may what is corporeal draw near to what in incorporeal?), but through the withdrawal of the passions; which, drawing close to the soul, through its affection for the flesh, have drawn it away from its friendship with God. When a man becomes clean of the stain he received through sin, and has returned to his natural beauty, restoring to its former resemblance the royal image within him, only then may he draw near to the Paraclete (Holy Spirit).
At first it may appear very difficult to you, but be assured, as it were from Almighty God, that this very name of our Lord Jesus Christ, constantly invoked by you, will help you to overcome all difficulties, and in the course of time you will become used to this practice and will taste how sweet is the name of the Lord. Then you will learn by experience that this practice is not impossible and not difficult, but both possible and easy. This is why St. Paul, who knew better than we the great good which such prayer would bring, commanded us to pray without ceasing. He would not have imposed this obligation upon us if it were extremely difficult and impossible, for he knew beforehand that in such case, having no possibility of fulfilling it, we would inevitably prove to be disobedient and would transgress his commandment, thus incurring blame and condemnation. The Apostle could have had no such intention.
Let us make ourselves the dwelling of peace, sanctification, and contrite prayer, without which no one will see God (Heb. 12:14). Let us long with the full assurance of faith for that vision promised to the pure in heart, and may we do everything to attain it, for it is accompanied by eternal life, unfading goodness, inexhaustible riches, unchanging and unending delight, glory and kingdom.
When we return to prayer after a period of reading we find a rejuvenated and invigorated soul, stirred by the desire for God. The best form of prayer is one that implants the clearest idea of God in the soul and thus makes space for the presence of God within us. We become a temple of God when our continuous meditation on Him is not constantly interrupted by ordinary worries, and the spirit is not disturbed by unexpected emotions. Thus, in flight from all things, the spirit who loves God can approach God who drives out everything that leads us to evil, and holds steadfastly to everything that leads to virtue.
Trials are of two kinds. Either affliction will test our souls as gold is tried in a furnace, and make trial of us through patience, or the very prosperity of our lives will oftentimes, for many, be itself an occasion of trial and temptation. For it is equally difficult to keep the soul upright and undefeated in the midst of afflictions, as to keep oneself from insolence and pride in prosperity.
A man is neither saved nor lost by the place he is in, but is saved or lost by his deeds. Neither a holy place nor a holy state is of use to him who does not fulfill the commandments of the Lord.
Even if thy soul should suffer somewhat from an offense, keep the sorrow within thyself. For it is said: 'Within me my heart is troubled' (Psalm 142:4), that is, the passion has not come out, but has been humbled like a wave that has broken up on the shore. Calm thy raging heart. Let thy passions be ashamed at the presence of reason in thee, as playful children are ashamed before a man commanding respect.
The closet of the soul is the body; our doors are the five bodily senses. The soul enters its closet when the mind does not wander hither and thither, roaming among things and affairs of the world, but stays within, in our heart. Our senses become closed and remain closed when we do not let them be attached to external sensory things, and in this way our mind remains free from every worldly attachment, and by secret mental prayer unites with God its Father. 'And thy Father which seeth in secret shall reward thee openly,' adds the Lord. God who knows all secret things sees mental prayer and rewards it openly with great gifts. For that prayer is true and perfect which fills the soul with Divine grace and spiritual gifts.
O holy choir! O sacred band! O unbroken host of warriors! O common guardians of the human race! Ye gracious sharers of our cares! Ye co-operators in our prayer! Most powerful intercessors!
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.
Since the angels and souls are incorporeal beings, they are not in a particular place, yet neither are they everywhere. They do not sustain all things, but themselves depend on Him Who sustains them. Hence they, too, are in Him Who sustains and embraces all things, and they are appropriately delimited by Him. The soul, since it sustains the body with which it is created, is everywhere in the body, although not in the sense of being located in a place or encompassed; but it itself sustains, encompasses and quickens the body, by virtue of the fact that it is in God's image.
Of the teachings and proclamations preserved in the Church, some we possess from written teaching, while others we have received in secret from the Tradition of the Apostles; these both have the same validity [ie. authority] for true religion. And no one will deny these points, at least if he is even moderately experienced in Church [matters].
