The color white of the dress the Empress wears represents the feminine. In alchemy, the colors white and red represent the opposites of duality that must be brought to a unity. Often the metaphor is used of a marriage between a queen dressed in white and a king dressed in red.
The heart shape of the shield on the RWS card, and the symbol of the planet Venus (on the shield, on the black pillow, and the pomegranates), are elements that refer to duality, of which the Empress represents one half:
Empress – emperor
Female – male
Venus – Mars
Heart (feeling) – head (thinking)
The RWS Empress also represents a complete spiritual awakening: the scepter, the crown with twelve stars, and the laurel wreath on her head, express this. A scepter stands for authority / mastery. The scepter on this card has a globe at the top, which refers to dominion over matter. The stars on the head of the empress have the shape of a hexagram (six-pointed star); the symbol that expresses the merger of the polarities.
The laurel wreath (a wreath of laurel branches) refers to mastery over sexual urges. This meaning is derived from the Greek myth of Apollo and Daphne. The god Apollo pursues the river nymph Daphne (a name that means Laurel), driven by lust. She desperately calls on the help of her father, the river god Penues. He turns his daughter into a laurel tree, through which she escapes Apollo’s persistent advances. Apollo turns the branches of the laurel tree into a wreath, which then becomes a symbol of chastity.
The moral of this myth is that the kundalini energy can only awaken and grow into a “tree of life” that reaches to the crown of man, if the sexual energy is preserved. A laurel tree is green all year round. This symbolizes the immortality of man after a completed kundalini awakening..
