In the next few weeks, try this exercise whenever you can. Work toward being able to speak naturally with no sense of urgency. Try to get to the point where thoughts about the process don't intrude too much. This is not an easy state to achieve, but it is well worth the effort.
Shuffle and cut the cards in the usual way. Hold the deck face down in one hand. Turn over the first three cards, and lay them in a row. Now, create a story around the cards. Don't try to come up with a clever scenario. Just allow any tale to unfold. In The Castle of Crossed Destinies by Italo Calvino, the characters tell their tales to each other using only tarot card images.
When you are through, set the first three cards aside, and deal three more for a new story. Or, if you like, keep the first three cards and lay out a fourth. Incorporate this card into the original tale. Continue developing the story by laying out new cards one at a time. The spirit of this exercise is spontaneous play. Stop if you feel any pressure or strain.
Next, lay out a new set of ten cards. Experiment with different story structures. Try starting with the outcome card (10) and working backward or building a story around a striking card pair. Explore new approaches with different sets of cards. For your readings, you will probably settle on a favorite approach, but it helps to know of other possibilities that you can draw on as needed.
