Worldly thoughts and material concerns blind the mind, or eye of the soul, like a cloth that covers the physical eyes; so long as we are not free of them, we cannot see.
The images of worldly vanity, upon which we have looked with entire pleasure and hearty sympathy, effeminate, weaken, and disturb the soul; they deprive us of purity of heart and of boldness before God.
Have you realized that the world and worldly cares do not hinder in fulfilling God's commandments, when there is zeal and attention? That silence and retirement from the world are useless, if laziness and negligence prevail?
Be careful not to neglect the small things, take care not to despise them as something insignificant. They are not insignificant; they are cancer for the soul, a bad habit. Let us therefore be vigilant. Let us pay attention to slight things, whilst they are still slight and before they become serious. Both the life of holiness and the sinful life start from little things and lead to greater ones, either good or bad.
Many are the obstacles that stand in the way of pleasing God; for not merely poverty and obscurity but also riches and honor are trials for the soul. Indeed, to some extent even the solace and ease which grace bestows on the soul can easily become a temptation and a hindrance if the soul is not properly conscious of these effects of grace and does not enjoy them with great circumspection and understanding: for the spirit of evil tries to persuade the soul to relax now it possesses grace, and so contrives to implant in it sluggishness and apathy.
It is impossible to look to heaven with one eye and to the earth with another. Likewise, it is impossible for our soul to cling at once to earthly and to heavenly things. We must select one or the other and cling to it...
Do not love the world, all the deceit of the world, for it passes by quickly along with all its pleasures. Only he who does the will of God remains unto the ages.
We must strive after a quiet mind. As well might the eye ascertain an object put before it while it is wandering restless up and down and sideways, without fixing a steady gaze upon it, as a mind, distracted by a thousand worldly cares, be able clearly to apprehend the truth. He who is not yet yoked in the bonds of matrimony is harassed by frenzied cravings, and rebellious impulses, and hopeless attachments; he who has found his mate is encompassed with his own tumult of cares; if he is childless, there is desire for children; has he children? Anxiety about their education, attention to his wife, care of his house, oversight of his servants, misfortunes in trade, quarrels with his neighbors, lawsuits, the risks of the merchant, the toil of the farmer. Each day, as it comes, darkens the soul in its own way; and night after night takes up the day's anxieties, and cheats the mind with illusions in accordance. Now one way of escaping all this is separation from the whole world; that is, not bodily separation, but the severance of the soul's sympathy with the body, and to live so without city, home, goods, society, possessions, means of life, business, engagements, human learning, that the heart may readily receive every impress of divine doctrine. Preparation of heart is the unlearning the prejudices of evil converse. It is the smoothing of the waxen tablet before attempting to write on it.
We know that the fight against sin which surrounds us on all sides is not an easy matter. The path of salvation is made narrower in proportion to the intensification in the world of evil and apostasy. But the ancient pagan world which surrounded the handful of the first Christians was no less corrupt. These latter, however, did not accede to the temptations of the pagan modes, even as some now do not accede to contemporary temptations.
Why do you increase your bonds? Take hold of your life before your light grows dark and you seek help and do not find it. This life has been given to you for repentance; do not waste it in vain pursuits.
A mind that dwells on everyday matters of life and vain things disperses the soul. One should turn inwardly, looking at the soul’s uncultivated vineyard, weeding it of all evil thorns and planting virtues there instead. But be wary, for this type of work is not easy at all. It requires perseverance and much patience. One will be confronted with a multitude of difficulties. Various writings of the Fathers are very helpful, and in our days are available by the dozens. In them one can find anything his heart desires, and anything it needs. The Fathers will lead you on the right spiritual path, if only you read them with humility and prayer.
Let us therefore not cling to things that even now are fleeing from us, but to things that remain and endure, so that we may be blessed with them for ever, by the grace and loving kindness of Jesus Christ our Lord...
