The Empress is a passive, wise, nurturing and supportive energy, associated with the natural world, abundance and fertility. She is the Mother archetype of Tarot. The Nine of Wands is a card of transition and includes all the lessons learned in the previous numbers. The Nine of Wands can be pressure, aggression or defense. The combination of the Empress and the Nine of Wands shows a woman who has experienced challenges and hard times.
To understand the elemental relationships between the cards, we should always take into account their actual meaning. The elements of the cards are Earth (Empress) and Fire (Nine of Wands). The Fire card can energize and expand the energies of the Earth card, while the Earth card offers a stable base so that those energies are materialized in an practical and consistent manner. In this case, the two cards fight each other, and the Nine of Wands would make the Empress more stubborn and rigid than she would normally be, while the Earth element of the Empress will make the energy of the Nine of Wands last for a longer period of time.
