My child, do you want to crush the head of the serpent? Openly reveal your thoughts in confession. The strength of the devil lies in cunning thoughts. Do you hold on to them? He remains hidden. Do you bring them to the light? He disappears. And then Christ rejoices, the prayer progresses, and the light of grace heals and brings peace to your nous and heart.
Love sinners, but hate their works, and do not despise them for their faults, lest you be tempted by the same. Remember that you share the earthly nature of Adam and that you are clothed with his infirmity.
But a sober and prudent man who desires to be saved, when he sees from what it is that he suffers harm, carefully preserves himself from evil remembrances, is not drawn into passionate thoughts, avoids meetings and conversations with those for whom he feels attraction and avoids every occasion for sin, fearing lest he himself ignite a fire within himself. This is the warfare which proceeds from one’s own lust, which a man brings on himself
As it is not possible to cross over the great ocean without a ship, so no one can attain to love without fear. The fetid sea, which lies between us and the noetic paradise, we may cross by the boat of repentance, whose oarsmen are those of fear. But if fear's oarsmen do not pilot the ship of repentance whereby we cross over the sea of this world to God, we shall be drowned in the fetid abyss. Repentance is the ship and fear is the pilot; love is the divine haven.
Stillness mortifies the outward senses and resurrects the inward movements, whereas agitation does the opposite, that is, it resurrects the outward senses and deadens the inward movements.
It is impossible for the soul to be liberated from turbulent thoughts without the virtue of non-possessiveness. And without peace of the bodily senses it is impossible for the soul to have a peaceful intellect. And if it does not come into temptations it will not acquire wisdom of the Holy Spirit. And without laborious and persistence in reading, it will not come to the discernment of thoughts. And without the stillness of thoughts, the intellect cannot move to seek the hidden mysteries of God.
As a man cannot remain unscathed who spares his enemy on the field of battle, so a man engaged in spiritual warfare cannot save his soul if he spares his body.
