The Devil is a Big Card with lots of potential interpretations. There’s codependency, there’s kink, there’s shame, addiction, workaholism, there’s that rather ambiguous term “shadow work”. All can apply to the Devil, and more. But I think one of the best ways to understand this card is:
When we pull the Devil, we believe that we do not have the power to change.
It’s very simple.
There are a million stories we might be telling about why we don’t have that power, and that’s our work in the Devil. We must expose those stories (they’re often running as background noise) and craft new ones; stories about our adaptability, capability, strength, and courage. It’s not easy, but it is simple.
Do not fall prey to the narrative that change is not within your power.
