When the intellect is pure, sometimes God Himself approaches and teaches it; and sometimes the angelic powers, or the nature of the created things that it contemplates, suggests holy things to it.
Through the Holy Spirit comes our restoration to paradise, our ascension into the kingdom of heaven, our return to the adoption of sons, our liberty to call God our Father, our being made partakers of the grace of Christ, our being called children of light, our sharing in eternal glory, and, in a word, our being brought into a state of all 'fullness of blessing,' both in this world and in the world to come, of all the good gifts that are in store for us, by promise hereof, through faith, beholding the reflection of their grace as though they were already present, we await the full enjoyment.
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.
The Holy Spirit sets us all on different paths: one man lives a life of silent solitude in the desert; another prays for mankind; still another is called to minister to Christ’s flock; to a fourth it is given to comfort or preach to the suffering; while yet another serves his neighbor by his goods or by the fruits of his labor - and all these are gifts of the Holy Spirit given in varying degrees: to one man thirtyfold, to another sixty and to some an hundred.
The Spirit is not united to the soul by drawing near to its place (for how may what is corporeal draw near to what in incorporeal?), but through the withdrawal of the passions; which, drawing close to the soul, through its affection for the flesh, have drawn it away from its friendship with God. When a man becomes clean of the stain he received through sin, and has returned to his natural beauty, restoring to its former resemblance the royal image within him, only then may he draw near to the Paraclete (Holy Spirit).
Whenever we enter the church and draw near to the heavenly mysteries, we ought to approach with all humility and fear, both because of the presence of the angelic powers and out of the reverence due to the sacred oblation; for as the Angels are said to have stood by the Lord's body when it lay in the tomb, so we must believe that they are present in the celebration of the Mysteries of His most sacred Body at the time of consecration.
When the Spirit of God comes down to man and overflows him with the fullness of His inspiration, then the human soul overflows with unspeakable joy, for the spirit of God fills with joy whatever He touches.
We know there are Angels and Archangels, Thrones, Dominions, Princedoms, Powers, Splendors, Ascents, Intelligent Powers or Intelligences, pure natures and unalloyed, immovable to evil, or scarcely movable; ever circling in chorus round the First Cause (or how should we sing their praises?) illuminated thence with the purest Illumination, or in one degree or another, proportionally to their nature and rank...so conformed to beauty and molded that they become secondary Lights, and can enlighten others by the overflowings and largesse of the First Light. Ministrants of God's Will, strong with both inborn and imparted strength, traversing all space, readily present to all at any place through their zeal for ministry and the agility of their nature...
And just as material fire, applied to the soft clay, changes it to hard pottery, so the fire of the Holy Spirit, when it penetrates our soul, though it should find it softer than the clay, yet it will make it more unyielding than iron. And the soul that a little while ago was stained with the mire of sin, is all at once more splendid than the sun.
People, until they come to know something greater, are satisfied with the little that they have. Man is like a village rooster who lives in a small enclosure with few people and farm animals about, who knows his ten hens and is content with this life, because he knows no more. But an eagle, who circles high in the clouds, and sees great distances with his sharp eyes, who hears the sounds of the earth and revels in its beauty, who knows many lands, seas and rivers, and sees a multitude of
animals and birds, would not be content to live in a small enclosure with a rooster. It is the same in spiritual life. Whoever has not known the grace of the Holy Spirit is like the rooster who does not know the flight of the eagle; he cannot comprehend the sweetness of tender emotion and love of God. He knows God from nature and from Scripture, he is satisfied with the law and is content with his lot as is the rooster, and does not feel sorrow that he is not an eagle. But he who has experienced the Lord through the Holy Spirit, he prays day and night, because the grace of the Holy Spirit calls him to love the Lord, and the sweetness of the Lord's love gives him the ability to carry the burdens of the world with ease; his soul pines only for the Lord and searches constantly for the grace of the Holy Spirit.
As earth thrown over it extinguishes a fire burning in a stove, so worldly cares and every kind of attachment to something, however small and insignificant, destroy the warmth of the heart which was there at first.
Do not the angels differ from us in this respect, that they do not want so many things as we do? Therefore the less we need, the more we are on our way to them; the more we need, the more we sink down to this perishable life.
I said to him, 'My sweet and good father, where do you receive the Eucharist on the Sabbath and the Lord's Day?' He said to me, 'Every Sabbath and every Lord's Day, an angel comes to me and gives me the Eucharist. And blessed is everyone who lives as a citizen in the desert on account of God and sees no human being -- He brings the Eucharist to them and comforts them. If they desire to see anyone, they are taken up to heavenly heights and they see them. They greet them and the hearts are filled with light. They rejoice in the Spirit and are glad in the good things they will never lack. When they see them, they are comforted, and they completely forget the afflictions that have been theirs. Afterwards they return to their places, and they are comforted for a long time, as though they had been removed to another world. Because of the great joy they have seen, they do not remember that this world even exists.'
