Cards that come up over and over again are one of those things that frustrate and annoy us as readers. I’ve had cards that, in a sense, stalked me. They would come up in my readings for myself and readings I got from others. I had no idea what they were doing. If this has ever happened to you, you know how annoying it is. Here are the two ways I tend to deal with them.
The first is to pull the card out (if you have several decks, pull it out of each). Study each detail (not the symbolism, just the image) in the card, memorize everything then sit down and start writing everything (the details, not the symbolism/interpretations) you remember. Write everything you saw then write down everything you think the card means. Look at how those meanings apply to your life. When I kept getting Justice I did this; I realized the card was telling me to focus on the energy I was putting into situations in my life and keep the positive because the energy I sent out was the energy that came back to me.
The other way to figure out what the card means in your life is to do a reading on that card. I always use the question “What does (the card) have to tell me right now?” I then do a simple reading (3 cards usually) focusing on the practical aspects of what comes up. When I did this for the Justice card, I got the 9 of Coins; for me this card is about being your true self and in the Legend, the Arthurian Tarot deck it conveys the message that your actions have consequences (both good and evil).
I try to use these methods in conjunction. It gives me a holistic understanding of why this card is here. The one bit of advice I will give is that if you don’t pay attention to a card that keeps coming up, you will continue to see it until you do. If you don’t learn the lesson the first time, it will keep coming until you do. Using either of these two methods you can gain insight into why cards reappear. They usually are telling you something you don’t want to hear or are ignoring in your life. Pay attention or they won’t go away.
