Struggle against lust

A certain monk had a struggle against defiled lusts. He got up and night and went to the elder and confessed to him the thoughts that were drawing him to defilement. The elder calmed him and the brother, have benefited, returned to his cell. But the struggle rose up against him again, and again he went to the elder. He did this a few times. The elder did not grieve him, but said, “Don’t give up, but it is better that you come to me whenever the demon disturbs you, and repel him by exposing your thoughts. By such a repulsion he will pass you by. For nothing so burns the demon of defilement as the revelation of his deeds [in confession before a spiritual father]. And nothing makes him so happy as the hiding of thoughts.” Thus the brother came to the elder eleven times, repelling his thoughts, and the brother’s temptation ceased.
