St. Macarius, quoted from Living Without Hypocrisy: Spiritual Counsels of the Holy Elders of Optina
There is no need to prove that bodily nourishment cannot satisfy the soul of man, nor can bodily drink quench its thirst. But even all this spirit of life, that shines through all created things, giving them life and harmony, is incapable of feeding and refreshing the soul.
The body directly receives food that is in essentials identical to the body. The body is of the earth, and food for the body is of the earth. This is why the body feels at home, among its own, in the world. But the soul suffers; it is crucified and suffers; it is disgusted and protests at having to receive food indirectly, and this a food not identical to itself. The soul therefore feels itself, in this world, to be in a foreign country, among strangers.
That the soul is immortal, and that it, in its essence, belongs to the immortal world, is proved by the fact that, in this earthly world, it feels itself a discontented traveller in a foreign land, and that nothing in the world can fully feed and refresh it. And even were the soul to be able to pour the whole universe into itself like a glass of water, its thirst would not only not become less but would, of a certainty, become greater. For then there would not remain in it one single illusory hope that it would, beyond the next hill, light on an unsuspected source of water.

“All our attention must be centered on the parable of the Prodigal Son. We all see ourselves in it as in a mirror. In a few words the Lord, the knower of hearts, has shown in the person of one man how the deceptive sweetness of sin separates us from the truly sweet life according to God. He knows how the burden of sin on the soul and body, experienced by us, impels us by the action of divine grace to return, and how it actually does turn many again to God, to a virtuous life.”

“When the soul of a man departs from the body, a certain great mystery is there enacted. If a person is under the guilt of sin, bands of demons and fallen angels approach along with the powers of darkness which capture the soul and drag it as a captive to their place. No one should be surprised by this fact. For if, while a man lived in this life, he was subject to them and was their obedient slave, how much more, when he leaves this world, is he captured and controlled by them?”
+ St. Macarius the Great, The Fifty Spiritual Homilies, Homily 22
“When the soul leaves the body, the enemy advances to attack it, fiercely reviling it and accusing it of its sins in a harsh and terrifying manner. The devout soul, however, even though in the past it has often been wounded by sin, is not frightened by the enemy’s attacks and threats. Strengthened by the Lord, winged by joy, filled with courage by the holy angels that guide it, and encircled and protected by the light of faith, it answers the enemy with great boldness: ‘Fugitive from heaven, wicked slave, what have I to do with you? You have no authority over me; Christ the Son of God has authority over me and over all things. Against Him have I sinned, before Him shall I stand on trial, having His Precious Cross as a sure pledge of His saving love towards me. Flee from me, destroyer! You have nothing to do with the servants of Christ.’ When the soul says all this fearlessly, the devil turns his back, howling aloud and unable to withstand the name of Christ. Then the soul swoops down on the devil from above, attacking him like a hawk attacking a crow. After this it is brought rejoicing by the holy angels to the place appointed for it in accordance with its inward state.”

“When my soul is about to be forcibly parted from my body’s limbs, then stand by my side and scatter the counsels of my bodiless foes and smash the teeth of those who implacably seek to swallow me down, so that I may pass unhindered through the rulers of darkness who wait in the air, O Bride of God.”
