The Devil, the fifteenth card of the Major Arcana, represents temptation, materialism, and the shadow aspects of the self. It emphasizes the importance of facing one's fears, recognizing personal limitations, and working to overcome self-imposed constraints. This card serves as a reminder of the value of self-awareness, introspection, and personal growth, as well as the potential consequences of succumbing to temptation and letting unhealthy patterns dominate one's life.

The imagery of the Devil card illustrates the power of temptation and the need to confront the shadow aspects of the self. The central figure is typically portrayed as a horned, goat-like creature or a demonic figure, often depicted with bat wings, a pentagram, or other occult symbols. This figure represents the darker side of human nature, the primal instincts, and the seductive power of material desires.

The Devil is often shown standing on a pedestal or an altar, symbolizing the influence and control that temptation and materialism can have over one's life. In some depictions, two figures, often a man and a woman, are shown chained to the pedestal, representing the bondage of addiction, obsession, or unhealthy relationships. These figures serve as a reminder of the consequences of giving in to temptation and the need to break free from self-imposed limitations.

The background of the card may depict a dark, foreboding landscape, symbolizing the shadowy realms of the subconscious mind and the darker aspects of the human psyche.
