Our holy fathers have renounced all other spiritual work and concentrated wholly on this one doing, that is, on guarding the heart, convinced that, through this practice, they would easily attain every other virtue, whereas without it not a single virtue can be firmly established.
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.
We must always pray to the Lord to tell us what to do, and the Lord will not let us go astray. Adam was not wise enough to ask the Lord about the fruit which Eve gave him, and so he lost paradise. David did not ask the Lord whether it would be a good thing if he took Beth-sheba to wife, and so he fell into the sins of murder and adultery. So with all the saints who sinned: they sinned because they had not called upon God to enlighten and help them. St. Seraphim of Sarov said, ‘When I spoke of myself I was often in error.’
When the door of steam baths is continually left open, the heat inside rapidly escapes through it; likewise the soul in its desire to say many things, dissipates the remembrance of God through the door of speech, even though everything it says may be good. Ideas of value always shun verbosity, being foreign to confusion and fantasy. Timely silence, then, is precious, for it is nothing less than the mother of the wisest thoughts.
Fasting, while of value in itself, is not something to boast of in front of God, for it is simply a tool for training those who desire self-restraint. The ascetic should not feel proud because he fasts; no artist ever boasts that his accomplishment is simply due to his tools; but he waits for the work itself to give proof of his skill.
It is well known that obedience is the chief among the initiatory virtues, for first it displaces presumption and then it engenders humility within us. Thus it becomes, for those who willingly embrace it, a door leading to the love of God. It was because he rejected humility that Adam fell into the lowest depths of Hades. It was because He loved humility that the Lord, in accordance with the divine purpose, was obedient to his His Father even to the cross and death, although He was in no way inferior to the Father; and so through His obedience He has freed mankind from the crime of disobedience and leads back to the blessedness of eternal life all who live in obedience. Thus humility should be the first concern of those who are fighting the presumption of the devil, for as we advance it will be a sure guide to all the paths of virtue.
Those pursuing the spiritual way should train themselves to hate all uncontrolled desires until this hatred becomes habitual. With regard to self-control in eating, we must never feel loathing for any kind of food, for to do so is abominable and utterly demonic. It is emphatically not because any kind of food is bad in itself that we refrain from it. But by not eating too much or too richly we can to some extent keep in check the excitable parts of our body. In addition we can give to the poor what remains over, for this is the mark of sincere love.
In order, then, that Christ may win us all unto obedience, He promises us surpassing honors, and deigns us the highest love, saving, `My mother and My brethren are those who hear the word of God and do it.' For who among men is so obdurate and ungentle, as to refuse to honor, and accord the most complete love to his mother and brethren? For the all-powerful law of nature, even without our will, obliges us to this. When, therefore, bowing our neck to the Savior's commands, we become His followers, and so are in the relation of a mother and brethren to Him, how does He regard us before God's judgment seat? Is it not with gentleness and love? What doubt can there be of this?: And what is comparable to this honor and goodness? What is there worthy of being matched with a gift thus splendid and desirable?
When we fervently remember God, we feel divine longing well up within us from the depths of our heart. The evil spirits invade and lurk in the bodily senses, acting through the compliancy of the flesh upon those still immature in soul. According to the Apostle, our intellect always delights in the laws of the Spirit (cf. Rom. 7:22), while the organs of the flesh allow themselves to be seduced by enticing pleasures. Furthermore, in those who are advancing in spiritual knowledge, grace brings an ineffable joy to their body through the perceptive faculty of the intellect. But the demons capture the soul by violence through the bodily senses, especially when they find us faint-hearted in pursuing the spiritual path. They are, indeed, murderers provoking the soul to what it does not want.
When a man walks in the fear of God he knows no fear, even if he were to be surrounded by wicked men. He has the fear of God within him and wears the invincible armor of faith. This makes him strong and able to take on anything, even things which seem difficult or impossible to most people. Such a man is like a giant surrounded by monkeys, or a roaring lion among dogs and foxes. He goes forward trusting in the Lord and the constancy of his will to strike and paralyze his foes. He wields the blazing club of the Word in wisdom.
Those who meditate unceasingly upon the holy and glorious name [of Jesus] in the depths of their heart can sometimes see the radiance of their own spirit-intelligence. For when the mind is profoundly concentrated on this invocation, we feel experientially how it starts burning off all the layers of dirt that normally suffocates the soul.
Where there is pride there cannot be grace, and if we lose grace we also lose both love of God and assurance in prayer. The soul is then tormented by evil thoughts and does not understand that she must humble herself and love her enemies, for there is no other way to please God.
Worldly thoughts and material concerns blind the mind, or eye of the soul, like a cloth that covers the physical eyes; so long as we are not free of them, we cannot see.
Among the virtues which must be instilled in a child's heart with special persistence, an important and fundamental place belongs to truthfulness, that is to say, a feeling of love for truth and an aversion towards falsehood. After obedience, this virtue should be given second place. If falsehood is the root of all sin, truth is the beginning and foundation for nearly all virtues, and for this reason parents must direct their attention primarily at nurturing truthfulness in children.
