The Priestess (or High Priestess, Papess, Pope Joan, Isis) is numbered two. This is the representation of the Goddess. She is the complementary partner of the Magician, possessing all his skill and ability, but with far more insight and psychism. She is more subtle yet somehow far more noticeable.
She is almost always shown with the Lunar Crescent, conveying her natural affinity with the forces of Nature and natural cycles. The Magician generates his own power, whereas the Priestess draws upon the forces of life itself.
She sits between two pillars with veils suspended between them - it is the Priestess who allows us to penetrate the innermost secrets of life. She is also the bridge between our conscious and Higher selves, by teaching us through our dreams and our subconscious. It is in our subconscious that we hold the keys to the Universe.
