The Major Arcana and Reversed Cards

The performers of the Major Arcana represent the central ideas of a reading.  They silently declare the significant events will soon occur.  The cards are number from zero to twenty-one.  During a reading, sometimes the cards face the reader.  On many occasions a card is upside-down or reversed.  This changes the meaning.  Now, the new principle is the opposite of the old meaning, in most cases.  It is imperative to not change the direction of a card.  It must be interpreted as it arrived.
