We come now to the conclusion of Conference 19 where Cassian and Germanus question Abba John about how one overcomes and does battle with vices that reemerge after the solitary life of the anchorite has been embraced. Abba John describes for them how they must engage in a kind of mental warfare - drawing the vices they see active in their hearts to mind and allowing themselves to be humbled by them and then apply the necessary reparation that is need; that is, apply the healing balm of penance and self rebuke to uproot the vestiges of these sins. The self-honesty as well as the self-awareness necessary for such an undertaking is great, especially since it is done without the support and guidance of others. The only vice where this is not to be done is fornication or unchastity. Since such vices arise out of and are connected to bodily appetites, the use of mental imagery could be very dangerous and simply draw one further into sin.
