Tarot and oracle are methods of introspection, exploration—and perhaps divination—using decks of cards. For some, it helps access personal psychological insight, or the collective unconscious; for others it connects them to the divine.
It can open a door for God/s, ancestors, and/or our higher self to share counsel, reminders, and direction. I use a variety of decks, depending on the desired kind of reading, and the person for whom I’m reading.
