St. Ignatius (Brianchaninov). "On Prelest". About Discretion in Reading the Patristic Books on the Monastic Life
The books of the Holy Fathers on the monastic life must be read with great caution. It has been noticed that a novice can never adapt books to his condition, but is always drawn by the tendency of the book. If a book gives counsels on silence and shows the abundance of spiritual fruits that are gathered in profound silence, the beginner invariably has the strongest desire to go off into solitude, to an uninhabited desert. If a book speaks of unconditional obedience under the direction of a spirit-bearing father, the beginner will inevitably develop a desire for the strictest life in complete submission to an elder.
God has not given to our time either of these two ways of life. But the books of the Holy Fathers describing these states can influence a beginner so strongly that out of inexperience and ignorance he can easily decide to leave the place where he is living and where he has every convenience to work out his salvation and make spiritual progress by putting into practice the evangelical commandments, for an impossible dream of a perfect life pictured vividly and attractively in his imagination.
St John Climacus says in his chapter about silence: “In the reflectory of a good brotherhood there is always some dog watching to snatch from the table a piece of bread, that is, a soul; and taking it in its mouth, it then runs off and devours it in a lonely spot” (Sermon 27).
