Each of the royalty cards represents a form of mastery, and all the cards in the suite of cups represent kinds of emotional mastery. The Knight of cups has mastered emotional desire. He is the lover within each of us who is willing to express his or her deep emotional passions. He allows himself to be pulled along by the dolphin steeds, yet he has the ability to let go the reigns at any time to navigate the water on his own with his special adaptation, fin feet. He sounds the trumpet to announce he is willing and able to make his passion known. The great whale shark, master of the depths, moves behind him.
