The birth of first love with all its freshness and inexperience, as well as the idealization that characterizes it, is expressed in this card. It is a fervent union, a youthful love whether consummated or not, the appearance of the Other in a vast romantic explosion that, if it causes disappointment, can cause terrible wounds.
Jodorowsky identifies the Three of Cups as the psychic site of idealised first love — radically open, potentially transformative, and equally capable of profound emotional injury.
