Provérbios 4:7
A brother asked a hermit, 'Abba, look here, I ask my elders questions, and they talk to me for the good of my soul, and I remember nothing they say. Is it any use asking questions when I gain nothing by it? I am deeply sinful.' There were two empty vessels nearby. The hermit said, 'Take one of those vessels and put oil in it, rinse it, pour out the oil, and bring the vessel back.' He did so. He said, 'Do it again.' He did so. After he had done it several times, the hermit said, 'Now, take both vessels and see which is the cleaner.' He answered, 'The one into which I put oil.' The hermit said, 'It's the same for the one who asks questions. Although you remember nothing that you have heard, your soul will be cleaner than that of someone who never even asks questions.' — The Desert Fathers, Sayings of the Early Christian Monks
Provérbios 4:23
Gerontius of Petra said, 'Many people who are tempted by pleasures of the flesh do not sin with the body but lust with the mind; they keep their bodily virginity but lust in their heart. It is better then, beloved, to do what is written, "Let everyone keep a close guard upon his heart" (Prov. 4:23).' — The Desert Fathers, Sayings of the Early Christian Monks
