Tarot is a system of cards used for divination. Their origin is unknown for certain, but they have ties to gypsies, and possibly to Egyptian and Kaballah belief systems. Each card has a designated meaning, that stays fairly consistent throughout the various versions of Tarot decks available. Many people use Tarot cards as tools or guides to receive intuitive information from God, spirit guides, angels, and akashic records.
Oracle cards, like Tarot, are also used to receive information from God, spirit guides, etc. Some deck variations have very specialized purposes or uses. They do not follow the same system of symbols as Tarot cards.
