The Major Arcana Tarot Cards are numbered 0-21, each card telling a story or conveying a message. Major Arcana cards represent more significant events or decisions, practically, emotionally and spiritually in a reading, whilst the Minor Arcana represent the more mundane, everyday aspects or events in a reading.
There is a specific order for the Major Arcana , but some decks deviate from this, for example, the Rider-Waite deck has the Strength card coming before the Justice card, and hence is numbered differently from the list below.
The Major Arcana naturally fall into two groups, with the Wheel of Fortune significantly at the mid point - this turning point between one half of life and the other is of critical importance
