Anyone seeking personal insight, clarity, or spiritual growth can benefit from tarot or oracle cards. Most tarot decks are based on the 78-card Rider-Waite structure, which includes both Major and Minor Arcana, providing structured meanings for the cards. In contrast, oracle cards are more open to interpretation and do not follow a specific structure. Oracle cards can cover any topic that the creator wishes to convey. These decks can vary in size; however, most contain between 32 and 45 cards and come with a guidebook that offers detailed meanings for each card.
