One must train oneself in self-reproach, that is, always accuse oneself & not others in one’s mind, reproach oneself and not others, and with a severe distrust of oneself accuse oneself of the failings which are covered up by our self-love, accuse ourself of our inclinations to sin. He who has self-reproach has peace, writes Abba Dorotheos, & will never be disturbed. If to such a one there should occur an illness, a wrong, a vexation, or some similar misfortune, he ascribes everything to his own sins & thanks God. If such a one is punished or reprimanded by the superior, he accepts all this as good & accepts every severe word against himself without murmuring or talking back, as the judgment of God.
When you shed floods of tears during prayer, do not exalt yourself for this, as though you were above many others. It is that your prayer has received help from above, so that, having zealously confessed your sins, you may incline the almighty to mercy by your tears.
Believe that dishonors and reproaches are medicines that heal the pride of thy soul, and pray for those who reproach thee, as for true physicians of thy soul, being assured that he who hates dishonor, hates humility, and he who avoids those who grieve him, flees from meekness.
The person who truly comes to serve God must prepare his soul, as it says in the Wisdom of Sirach (2:1), for temptations. Thus, that he will never be surprised or disturbed by what happens, believing that nothing happens without the providence of God and where there is the providence of God certainly what happens is good and for the benefit of the soul. For, everything that God does, He does for our benefit and because He loves us and has pity on us. We must, as the Apostle says, 'In everything give thanks' (1 Thess. 5:18), for His goodness.
If we were willing to make even small efforts, we would not suffer either distress or difficulty. For if a man urges himself to make efforts, then, as he continues them, he gradually makes progress and later practices virtues with tranquility; for God, seeing him urge himself, sends him help. So let us urge ourselves, for, although we have not reached perfection, if we make efforts, through efforts we shall receive help, and with this help shall acquire all kinds of virtues. Therefore one of the fathers said, 'Give blood and receive spirit,' that is, strive and you will become practiced in virtue.
A mind from which the thought of God has been carried away and which has thus become far removed from remembering Him, is also indifferent to sin with the outer senses. For such a mind can guide neither the hearing nor the tongue, since zest to work on itself has gone out of it.
