I wish I could persuade spiritual persons that the way of perfection does not consist in many devices, nor in much cogitation, but in denying themselves completely and yielding themselves to suffer everything for the love of Christ. And if there is failure in this exercise, all other methods of walking in the spiritual way are merely a beating about the bush, and profitless trifling, although a person should have very high contemplation and communication with God.
The beginning of the mortification both of the soul’s desire and of the bodily members is much hard work. The middle is sometimes laborious and sometimes not laborious. But the end is insensibility and insusceptibility to toil and pain. Only when he sees himself doing his own will does this blessed living corpse feel sorry and sick at heart; and he fears the responsibility of using his own judgment.
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.
Let your very dress urge you to the work of mourning, because all who lament the dead are dressed in black. If you do not mourn, mourn for this cause. And if you mourn, lament still more that, by your sins, you have brought yourself down from a state free of labors to one of labor.
Mourning according to God is sadness of soul and the disposition of a sorrowing heart, which ever madly seeks that for which it thirsts; and when it fails in its quest, it painfully pursues it, and follows in its wake grievously lamenting. Or thus: mourning is a golden spur in a soul which is stripped of all attachment and of all ties, fixed in a soul which is stripped of all attachment and of all ties, fixed by holy sorrow to watch over the heart.
If the Apostles and Martyrs, while still in the body, can pray for others, at a time when they must still be anxious for themselves, how much more after their crowns, victories, and triumphs are won! One man, Moses, obtains from God pardon for six hundred thousand men in arms; and Stephen, the imitator of the Lord, and the first martyr in Christ, begs forgiveness for his persecutors; and shall their power be less after having begun to be with Christ? The Apostle Paul declares that two hundred three score and sixteen souls, sailing with him, were freely given him; and, after he is dissolved and has begun to be with Christ, shall he close his lips, and not be able to utter a word in behalf of those who throughout the whole world believed at his preaching of the Gospel? And shall the living dog Vigilantius be better than that dead lion?
During the divine services, and at the very moment when the Mysteries (e.g., Holy Communion) are being accomplished, this vile enemy often blasphemes the Lord and the holy Sacrifice that is being consecrated. Wherefore, we clearly learn that it is not our soul that pronounces these unspeakable, godless and unthinkable words within us, but the God-hating fiend who fled from Heaven for uttering blasphemies against the Lord there too, as it would seem. For if these shameless and disgraceful words are my own, how could I worship after receiving the Gift? How can I praise and revile at one and the same time?
Stint your stomach and you will certainly lock your mouth, because the tongue is strengthened by an abundance of food. Struggle with all your might against the stomach and restrain it with all sobriety. If you labor a little, the Lord will also soon work with you.
Greater than baptism itself is the fountain of tears after baptism, even though it is somewhat audacious to say so. For baptism is the washing away of evils that were in us before, but sins committed after baptism are washed away by tears. As baptism is received in infancy, we have all defiled it, but we cleanse it anew with tears. And if God in His love for mankind had not given us tears, those being saved would be few indeed and hard to find.
