There are some suggested affirmations for each card in the deck. It's also great to come up with your own. These will be better tailored to your specific situation and the way you think about the world.
One way of working with affirmations and these cards is to simply pick a card and use an affirmation that fits it. For example, the Tree might lend itself to something like: "I feel healthy and well." Or you might say "I communicate effectively and harmoniously," if you draw the Songbirds.
Another way of using this aspect of the deck is to throw a reading, and pick one or two cards that feel most relevant. Here, I threw a line of five:
|Clover, Key, Hill Fort/Tower, Meadow/Garden, House.|
I see this saying that although the comfort of being in a group with clear structures can be appealing, sometimes we need isolation if we're going to have an 'aha' moment of inspiration. With the Tower at the centre, and this reading, I might use the affirmation: "I gain perspective through time alone."
You can also create one or two affirmations from the reading itself. For instance, here I might say: "I take the opportunity to solve problems by myself." (Clover/Key/Tower) And: "I use these insights to feel more comfortable within group structures." (Key/Tower/Meadow/House)
You can stick to a simple one card draw and using an affirmation from the book, or create more personal affirmations for yourself from a reading. Either way, this practice can help strengthen your resolve and bring you greater clarity.
