True repentance consists of withdrawing from sin and nurturing hatred for it. For, lo, when someone says from his heart: I have hated deceit and been repelled by it - then God accepts him with joy.
According to the blameless faith of the Christians which we have obtained from God, I confess and agree that I believe in one God the Father Almighty; God the Father, God the Son, God the Holy Ghost; I adore and worship one God, the Three. I confess to the oeconomy of the Son in the flesh, and that the holy Mary, who gave birth to Him according to the flesh, was Mother of God. I acknowledge also the holy apostles, prophets, and martyrs; and I invoke them to supplication to God, that through them, that is, through their mediation, the merciful God may be propitious to me, and that a ransom may be made and given me for my sins. Wherefore also I honour and kiss the features of their images, inasmuch as they have been handed down from the holy apostles, and are not forbidden, but are in all our churches.
Join to every breath a sober invocation of the name of Jesus and the thought of death with humility. Both these practices bring great profit to the soul.
Just as one cannot buy education or artistic skills for any price without working at it, so one cannot attain the habit of exercising the virtues without zeal and diligence.
Exercise patience out of love for your fellow man. Exercise patience in order to benefit your soul. For if you do not take your soul into consideration, you lose your patience.
How can one avoid distractions in prayer? If one abides in the presence of God. Indeed, when in the presence of one's judge and one's master, and speaking with him, one does not let one's eyes wander elsewhere. How much more should the one who approaches the Lord never turn away the eye of his heart, but fix it on Him who searches the reins and the heart.
The world is much stormier than the surging waves, and sin agitates it more than wind does the sea. There are times when the waters of the sea are calm, when the winds are concealed in their hiding places; but in the world waves of desire are ceaselessly whipped up, and the wind of deceit blows against the doors of the world’s vessels. Yet the day when it will abate is at hand.... Blessed is he who has completed his path in the world without falling into its snares.
It is not always possible to fulfill the usual rules; one must take circumstances into account and try to fulfill what they make possible, as far as one can. The demons themselves are not unmindful of this law. So, being in constant enmity with us, they prevent us from doing what is possible and urge us to do what is impossible.
Waves of temptation of every sort were aimed at the righteous ones, but they did not grow faint. Glory did not make them haughty, nor did abusive treatment cause them to be despondent. They were always the same; never did the fragrance of their virtues falter.
Forgive and pray, in order to live your life serenely. And do not do to others that which you do not want them to do to you, or return the evil which they have done to you.
Whether you pray with brethren or alone, try to pray not simply as a routine, but with conscious awareness of your prayer. Conscious awareness of prayer is concentration accompanied by reverence, compunction and distress of soul as it confesses its sin with inward sorrow.
