One of the Fathers said: just as it is impossible for a man to see his face in troubled water, so too the soul, unless it be cleansed of alien thoughts, cannot pray to God in contemplation.
When the attention of the mind is fixed in the heart it is possible to control what happens in the heart, and the battle against the passions assumes a rational character. The enemy is recognized and can be driven off by the power of the Name of Christ.
Blessed is the Good One Who opens His door to the good that they might enter therein, and also does not lock the door of His goodness to the evil if they are converted. Blessed is He Who grants everyone the means to inherit the heavenly kingdom: the righteous inherit it through good deeds, and sinners through repentance. Blessed is He Who for the sake of sinners gave Himself up to death and revilement, Who suffered humiliation in order to grant sinners life.
Woe is he who knowingly chooses to sin with the intention to repent when morning comes, for he knows not what the coming day or the night that precedes it will bring.
If a righteous man can barely be saved, then where will I end up, I who am lawless and sinful? If the path that leads to life is strait and narrow, then how can I be vouchsafed such good things, I who live a life of luxury, indulging in my own pleasures and dissipation? But Thou, O Lord, my Saviour, Son of the true God, as Thou knowest and desirest it, by Thy grace alone, freely turn me away from the sin that abides in me and save me from ruin.
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
Many people will be found pleasing God, for whom it will be possible, in the mountains and in desert places, to save themselves by much prayer….for God, seeing their many tears and sincere faith, will have mercy on them, as a tender Father, and will keep them.
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.
If Moses, who was a god to Pharaoh, was shut out from the Land of Promise because of one word, how much more will not the evil speech of our tongue, by which we offend and hurt both God and man, shut us out from heaven?
