Not he is chaste in whom shameful thoughts stop in time of struggle, work and endeavor, but he who by the trueness of his heart makes chaste the vision of his mind not letting it stretch out towards unseemly thoughts.
An old man was asked, 'How can I find God?' He said, 'In fasting, in watching, in labors, in devotion, and, above all, in discernment. I tell you, many have injured their bodies without discernment and have gone away from us having achieved nothing. Our mouths smell bad through fasting, we know the Scriptures by heart, we recite all the Psalms of David, but we have not that which God seeks: charity and humility.'
When a man walks the straight path, he does not have a cross. But when he begins to step away from one side to another, then various circumstances arise that push him back onto a right path. These pushes comprise a man's cross. They vary, of course, according to what each individual needs.
How can one say that a man has attained purity? - When he sees all men as being good, and when none appears to him to be unclean and defiled - then he is indeed pure in heart.
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.
Love of God proceeds from conversing with him; this conversation of prayer comes about through stillness, and stillness comes with the stripping away of the self.
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.
Just as over-drinking is a matter of habit, so too from habit comes over-sleeping. Therefore we must struggle with the question of sleep, especially in the early days of obedience, because a long-standing habit is difficult to cure.
God often permits virtuous men to be tried by something: He permits temptations to rise up against them on all sides... Whether these trials come from men, demons or flesh, let it be a cause for thanksgiving. For God cannot show his favor to a man who desires to dwell with Him, except by sending him trials for the sake of truth; just as no man can become worthy of this greatness... without the grace of Christ... St. Paul plainly calls it a gift... 'For unto you it is given in behalf of Christ, not only to believe in Him, but also to suffer for His sake' (Phil. 1:29).
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.
