The esoteric function of The Devil Tarot Card, as explained by my Tarot teachers at The Tarot School, is laughter. What does this mean? It means that when The Devil card appears in a reading, it potentially means a belly laughing good time! Think about it . . . no one has a better time than The Devil. Keep this in mind when he rears his raunchy head.
I especially enjoy The Douchebag card . . . a reversed Knight perhaps? Thanks Winston!
