The Justice Tarot card has to do with moral sensitivity and that which gives rise to empathy, compassion, and a sense of fairness. Since the time of Solomon, this image has represented a standard for the humane and fair-minded treatment of other beings.
Often including the image of a fulcrum or scale which helps to balance competing needs against the greater good, and a two-edged sword to symbolize the precision needed to make clear judgments, this card reminds us to be careful to attend to important details. It's a mistake to overlook or minimize anything where this card is concerned. The law of karma is represented here -- what goes around comes around.
