Cups are emotional indeed.  We need only to glance at this suit to realize this.  Water is featured throughout the Cups.  This is the suit of emotional attachment and caring.  Not surprisingly relationships are featured throughout the Cups.  This suit illustrates riding high one minute and being low the next.  Artists and those who are creative are symbolized by the Cups.  Creativity is fluid, it cannot be organized or pinned down and neither can this suit.  The zodiac signs associated with the cups are Cancer, Pisces and Scorpio because they seek to understand the subtleties of living life.  These signs appreciate that there is more to life than what appears on the surface.  They delve into the undercurrent just as the Cups do.  We use Cups to celebrate by filling them to the brim and we also use them to contain and seal away our emotions when difficult times arise.  Whether happy or sad, the Cups are there to see us through it all.
