Tarot cards have had a number of uses historically, including for card games, but today they are primarily used for seeking answers to questions, often as a quest for divine guidance or inspiration. Readers of all experience levels can experience the cards' answer being given in an uncanny way, revealing something hidden but recognizable in a situation or thought process. Therein lies the significance of the Major (22) and Minor (56) Arcana cards, unearthing "secrets" buried in the deeper realms of consciousness and experience.
