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.
Prayer offered up at night possesses a great power, more so than the prayer of the day-time. Therefore all the righteous prayed during the night, while combating the heaviness of the body and the sweetness of sleep and repelling bodily nature.
The key to Divine gifts is given to the heart by love of neighbor, and, in proportion to the heart's freedom from the bonds of the flesh, the door of knowledge begins to open before it.
Do not be surprised that when you draw near to virtue, grievous and intense tribulations come to you on all sides: for virtue is not considered virtue, if it does not involve hard work.
The fact that repentance furnishes hope should not be taken by us as a means to rob ourselves of the feeling of fear, so that one might more freely and fearlessly commit sin. For behold how God in every wise preached fear in all the Scriptures and showed Himself to be a hater of sin.
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.
Compunction comes when you consider how much you have grieved God Who is so good, so sweet, so merciful, so kind, and entirely full of love; Who was crucified and suffered everything for us. When you meditate on these things and other things the Lord has suffered, they bring compunction.
Love is the Kingdom, which the Lord mystically promised His disciples to eat in His Kingdom. For when we hear Him say, 'You shall eat and drink at the table of My Kingdom,' what do we suppose we shall eat, if not love? Love is sufficient to nourish a man instead of food and drink. This is the wine 'which makes glad the heart of man.' Blessed is he who partakes of this wine! Licentious men have drunk this wine and felt shame; sinners have drunk it and have forgotten the pathways of stumbling; drunkards have drunk this wine and became firm in virtue; the rich have drunk it and desired poverty; the poor have drunk it and been enriched with hope; the sick have drunk it and become strong; the unlearned have taken it and been made wise.
St. John Climacus was asked if there are reliable signs by which it's possible to know whether a soul is drawing near to God or moving away from Him. After all, regarding ordinary things there are clear signs as to whether they're good or not. When, for instance, cabbage, meat or fish begins to rot, it's easy to notice it, since the rotting object begins to give off a foul odor, the color and taste change, and its external appearance witnesses to its deterioration. Well, and what about the soul? After all, it's bodiless and can't give off a bad smell or change its appearance. To this question the Holy Father replies, 'A sure sign of the deadening of the soul is the avoidance of church services.'
But if you give a strong body rest and ease and idleness, all the passions dwelling in the soul are intensified. Then, even if the soul has a great desire for good, even the very thought of the good that is desired will be taken from you.
