If you want cure your soul, you need four things. The first is to forgive your enemies. The second is to confess thoroughly. The third is to blame yourself. The fourth is to resolve to sin no more. If we wish to be saved, we must always blame ourselves and not attribute our wrong acts to others. And God, Who is most compassionate, will forgive us.
This prayer should never be absent from you: 'Lord Jesus Christ, Son and Logos of the living God, through the Theotokos and all the Saints, have mercy upon me, Thy sinful and unworthy servant.' (This is the actual Jesus Prayer: 'O LORD JESUS CHRIST, SON OF GOD, HAVE MERCY UPON ME, A SINNER.') Always say this prayer both with your mouth and with your mind, day and night, wherever you may be, whether eating, walking, working, or sitting. Always meditate on it, as it benefits you a great deal, frees you here from every evil, delivers you there from eternal Hell, and renders you worthy of going to Paradise, our heavenly country.
When you see someone suffering great dishonor, you may be sure that he was carried away by thoughts of self-esteem and is now reaping, much to his disgust, the harvest from the seeds which he sowed in his heart.
In times of any sorrow, illness, poverty, need, disagreements, and any difficulty, it is better to spend less time in ruminating and talking to ourselves, and more often to turn to Christ our God and to his most pure Mother in prayer, even if it is only a brief one. Through that, the spirit of bitter despondency will be driven away, and the heart will be filled with joy and with hope in God.
When the first order of angels fell from the angelic glory and became demons, the other nine orders humbled themselves and worshipped the All-holy Trinity, and remained in their place and rejoice forever. We, too, my brethren, must reflect what an evil thing pride is - that it cast down the devil from angelic glory and he will always burn in Hell - and that humility kept the angels in Heaven, and they rejoice perpetually in the glory of the Holy Trinity. Let us then, my brethren, avoid pride, because it is the first daughter of the devil, is a path that leads to Hell; and let us have humility, because it is angelic—it is a path that leads to Paradise.
Let us go forward with the heart completely attentive and the soul fully conscious. For if attentiveness and prayer are daily joined together, they become like Elias' fire-bearing chariot, raising us to heaven. What do I mean? A spiritual heaven, with sun, moon and stars, is formed in the blessed heart of one who has reach a state of watchfulness, or who strives to attain it.
When tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
There is a sin which is always 'unto death' [1 Jn 5:16]; the sin which we have not repented. Even a saint's prayers will not be heard for the unrepented sin. The person who repents correctly does not imagine that his sins are cancelled through his own effort; but knows that through this effort he makes peace with God.
Be glad and rejoice that you were granted to be pious Orthodox Christians. Likewise again cry and mourn for the impious and unbelievers who walk in darkness, in the hands of the devil.
If anyone wants to drive out the demons, he must first subdue the passions, for he will banish the demon of the passion which he has mastered. For example, the devil accompanies anger; so it you control your anger, the devil of anger will be banished. And so it is with each of the passions.
