The Priestess is a powerful aspect of the sacred feminine, representing a very special connection between the conscious and unconscious minds.
Making the Unknown, Known
The Priestess, her home is the spirit, and she, like no other, understands the dark night of the soul. She has moved through psychological individuation, so she is not afraid to stand alone.
As a medium, she is constantly processing the unconscious psychic contents of others and the environment, yet a woman with a solid footing in the spirit and a healthy ego can separate her own thoughts and feelings from those of others.
She's very perceptive and has an innate ability to know when something is not right. The Priestess, like the great Octavia Butler, can recognize the cultural events happening around her, make connections between them, and predict the future. Have you read Parable of the Sower?
She is extremely sensitive to the psychic contents of others, which makes her vulnerable to life experiences that are not her trajectory. Still, this sensitivity also allows her to understand how they're feeling and what they need.
