The Six in the Minor Arcana represents a rest after the struggles of the Fives. Take a break; you've earned it.
 
Cups are the element of water. Water symbolizes creativity, emotion and love.
 
The Six of Cups can appear in different guises in different decks, but always it represents a trip to the past; to happy memories; to that time in your life when you relished simple pleasures and joys.
 
The Six may also mean a meeting with an old friend or an encouragement to re-visit those places and activities that brought you enjoyment from the past.
