Excerpt from Dark Days Tarot Guidebook by Emily Mundy:
The Justice card speaks to everything about fairness and balance, the teetering of two opposites, and the seeking and administering of harmonious living. Associated with the sign of the Libra (an air sign, indicating communication), the scales of the Justice card balance heavenly and earthly laws in the querent’s personal and surrounding life. The querent is certain to “reap what they have sewn” in relation to previous actions and values. The deserving side of the current argument will win. Concrete karma and consequence will follow either positively or negatively. This card is a reminder to make progress with an open mind and to restore workability and compromise in your future. Proceed with balance.
