Tarot cards are a set of 78 cards used for divination and self-reflection. Each card has unique imagery and symbolism, divided into two main groups: the Major Arcana, which consists of 22 cards representing significant life events, and the Minor Arcana, which includes 56 cards that focus on everyday situations. During a reading, a tarot reader shuffles the cards and lays them out in a specific pattern, known as a spread. The reader interprets the cards' meanings based on their positions and relationships to provide insights into the querent's past, present, and future.
