A Tarot deck is a set of cards used for divination, self-reflection, and guidance. Typically consisting of 78 cards, it is divided into two main sections: the Major Arcana, which includes 22 cards representing significant life events and spiritual lessons, and the Minor Arcana, which contains 56 cards divided into four suits that reflect everyday experiences and challenges. Each card in a Tarot deck has its own imagery, symbolism, and meanings, which can vary between different decks. Readers often interpret the cards based on their positions in a spread, allowing for insights into the past, present, and future.
