Justice tarot card

Card 1 - Justice

The Justice tarot card is a symbol of truth, fairness, and law. As she sits in her chair, the scales in her left hand represent how intuition should balance logic. She symbolizes impartiality with the double-edged sword in her right hand. The clarity in thought which is required to dispense justice are symbolized by the square on the crown she wears. Behind her, there is a purple cloak and standing grey pillars. Beneath her red cloak, which is held together by a clasp, she shows the tip of a white shoe. This is a spiritual reminder that what she delivers are the outcomes of their actions.

Hierophant tarot card

Card 2 - Hierophant

The card depicts a religious figure that sits in a rather formal environment characteristic for a church. He is wearing three elaborate vestments which are designated to represent the three different worlds. His right hand is properly raised in an act of benediction, a sign of blessing – it s the same hand that the Magician has raised. In his other hand, he carries a triple cross, which is associated traditionally with the pope. Each of the horizontal bars in the cross are thought to represent the Father, the Son and the Holy Ghost. Beneath him, two acolytes are seated, representing the transfer of sacred knowledge within institutions. Through these acolytes, the card also comes to represent following the path to knowledge and education. This card is also known as the High Priest in certain decks - as well as the Pope. He is acting as the masculine counterpart of another card which is known as the High Priestess. This card is ruled by Taurus.

Emperor tarot card

Card 3 - Emperor

In the Emperor tarot card, a stoic ruler figure can be seen on his throne, which is adorned with the heads of four rams, representing his astrological sign - Aries. In one hand, he carries a scepter, representing his reign and his right to rule, and in the other an orb, a symbol of the kingdom that he watches over. The long beard of the emperor represents his vast experience; over time he has learned much about what it takes to rule, to establish power, authority and complete order for the benefit of his people. Behind him, the barren mountains shows his determination, his ambition for greater heights and his leadership capability. Contrast this with his complement, the Empress, whose flowing fields are filled with nurturing kindness. The Emperor instead rules with grit, strength and force.
