Shirley uses a variety of different card decks in her interpretive card readings.  Shirley uses Osho Zen tarot cards, medicine cards, Kabbalah cards, Ask Your Guides cards, Sacred Path cards, Goddess cards and angel cards.  Each reading is unique and Shirley chooses the different cards based on what she is receiving intuitively.  Shirley will add more decks as she is guided to do so.

Shirley calls them Interpretive card readings because the cards help her to access her own intuition and guidance from her own guides and teachers, as well as the guides and teachers of the client.  The meaning of the cards will often change with different readings and may vary from the meanings described in the books that came with each deck .  Therefore, it is an interpretation as opposed to Shirley being dependent on a particular meaning or meanings as described in the manual.
