The figure is seated between pillars, like the High Priestess, and on this account it seems desirable to indicate that the moral principle which deals unto every man according to his works, while differs in its essence from the spiritual justice which is involved in the idea of election. The latter belongs to a mysterious order of Providence, in virtue of which it is possible for certain men to conceive the idea of dedication to the highest things. The operation of this is like the breathing of the Spirit where it wills, and we have no canon of criticism or ground of explanation concerning it. The pillars of Justice open into one world and the pillars of the High Priestess into another.
Justice has the scales of equality and impartial judgment in one hand, and the sword of decision in the other. In the tarot, Justice represents the understanding that life is ultimately fair and just. Even though the vagaries of day-to-day life tend to make us doubt this fact, Justice reminds us that there is divine balance. Notice the similarity between the Emperor and Justice. Both cards stand for universal order; the Emperor in its underlying structure, Justice, in the action of karma, cause and effect.
Justice often appears when you are concerned with doing what is right or making sure you receive your due. Also, when you are feeling the impact of a past mistake or good deed. The cause you set in motion at one time is now returning to you as an effect.
Sometimes Justice is a signal to do what needs to be done. A time comes when responsibilities must be accepted, and accounts settled. The past will continue to haunt you if you do not recognize your mistakes and make amends for them. You will need to weigh matters carefully and perhaps make important decisions about your future course.
