Questioning Security

Ὅταν τινὲς τῶν ἀκαθαρτων λογισμῶν ταχέως φυγαδευθῶσιν, ζητήσωμεν τὴν αἰτίαν πόθεν τοῦτο συμβέβηκε· πότερον διὰ τὴν σπάνιν τοῦ πράγματος, τοῦ δυσπόριστον εἰναι τὴν προσοῦσαν ἡμῖν ἀπάθειαν οὐκ ἰσχυσαν καθ' ἡμῶν οἱ ἐχθροί; Οἷον, εἴ τις τῶν ἀναχωρούντων ἐνθυμηθείη ὑπὸ δαίμονος, τῆς πρώτης πόλεως πνευματικὴν κυβέρνησιν πιστευθῆναι, οὗτος δῆλον, ὅτι οὐ χρονίσει λογισμὸν τοῦτον φανταζόμενος, καὶ ἡ αἰτία ἐκ τῶν λεγομένων γίνεται γνώριμος· εἰ δέ τις πόλεως, καὶ τῆς τυχούσης γίνεται, καὶ ὁμοίως λογίζεται, οὗτος μακάριος τῆς ἀπαθείας ἐστίν. Ὁμοίως δὲ καὶ ἐπὶ τῶν ἄλλων λογισμῶν εὑρωθήσεται ὁ τοιοῦτός τρόπος ἐξεταζόμενος. Ταῦτα δὲ ἀναγκαῖον εἰδέναι πρὸς τὴν ἡμετέραν προθυμίαν, καὶ δύναμιν, ἵνα εἴδωμεν, πότερον ῆ̀ τὸν Ἰορδάνην παρήλθομεν, καὶ ἐγγύς ἐσμεν τῆς πόλεως τῶν Φοινίκων, ἢ ἐν τῇ ἐρήμῳ διάγομεν, καὶ ὑπὸ τῶν ἀλλοφύλων τυπτόμεθα.  Εὐάγριος ὁ Ποντικός, Περὶ διαφόρων πονηρῶν λογισμῶν, Κεφαλ Κβ' Source: Migne PG 79 1224d-1225a

When unclean thoughts have been driven away quickly, we should seek the cause of how this has happened. Was it because of the impossibility of the thought as action or because of our state of dispassion, that enemies failed to overcome us? For example, if a solitary, by the prompting of demons, imagines himself entrusted with the spiritual rule of a great city, he will not dwell on this thought for long because he knows the cause of why it has come to him. But if a man does become the spiritual guide of a city and he thinks in the same manner, he is blessed with dispassion. A similar measure shall be found applicable to other thoughts. And we should be aware of these things in order to estimate our commitment and strength, that we know whether we have crossed the Jordan and are near the palm trees, or are still in the wilderness and are assaulted by the enemy. Evagrius Ponticus, On Various Wicked Thoughts, Chap 22
