The answer on the devils illusion, because he promises us the peace of a vaster solitude.
Abraham: Never to be resorted to by men at all is a sign of an unreasonable and ill-considered strictness, or rather of the greatest coldness. For if a man walks in this way, on which he has entered, with too slow steps, and lives according to the former man, it is right that none—I say not of the saints—but of any men should visit him. But you, if you are inflamed with true and perfect love of our Lord, and follow God, who indeed is love, with entire fervour of spirit, are sure to be p. 540 resorted to by men, to whatever inaccessible spot you may flee, and, in proportion as the ardour of divine love brings you nearer to God, so will a larger concourse of saintly brethren flock to you. For, as the Lord says, “A city set on an hill cannot be hid,” 2321 because “them that love Me,” saith the Lord, “will I honour, and they that despise Me shall be contemned.” 2322 But you ought to know that this is the subtlest device of the devil, this is his best concealed pitfall, into which he precipitates some wretched and heedless persons, so that, while he is promising them greater things, he takes away the requisite advantages of their daily profit, by persuading them that more remote and raster deserts should be sought, and by portraying them in their heart as if they were sown with marvellous delights. And further some unknown and non-existent spots, he feigns to be well-known and suitable and already given over to our power and able to be secured without any difficulty. The men also of that country he feigns to be docile and followers of the way of salvation, that, while he is promising richer fruits for the soul there, he may craftily destroy our present profits. For when owing to this vain hope each one separates himself from living together with the Elders and has been deprived of all those things that he idly imagined in his heart, he rises as it were from a most profound slumber, and when awake will find nothing of those things of which he had dreamed. And so as he is hampered by larger requirements for this life and inextricable snares, the devil will not even allow him to aspire to those things which he had once promised himself, and as he is liable no longer to those rare and spiritual visits of the brethren which he had formerly avoided, but to daily interruptions from worldly folk, he will never suffer him to return even to the moderate quiet and system of the anchorites life.
