There are 78 cards in a standard tarot pack. There are 22 major arcana cards and 56 minor arcana cards. The minor arcana cards are divided equally among four suits, usually swords, pentacles, wands and cups.
Tarot cards are used primarily for divination. The major arcana cards, such as the high priestess, the fool and the wheel of fortune, are not associated with suits. Their meanings are divined by their subject's intuitive connection to the real world. The suits of the minor arcana are each associated with a theme that is important in the divination process. Swords are linked to conflict. Pentacles relate to finances. Wands are associated with the intellect and positions of power. Cups deal with emotions.
