"(never) have a conversation with Satan"
Sound advise! Defeating Satan is not an act of the mind but of the heart. From the Book of Genesis we learn that Satan is the craftiest of all creatures. Wisdom and Charity makes us masters over demons. It's a matter of disciplining our thoughts and emotions via a Life of Holiness and frequent use of the Sacraments. The Sacred Heart of Jesus is Victorious.
