Whether we know it or not, our lives are acts of imagination
and the world is continually re-imagined through us.
– Michael Meade
Given that yesterday marked a New Moon phase, it’s certainly appropriate that all three cards here are tied to the moon. Notice that it is represented in each card:
This spread is all about intution, the unconscious, secrets, that which is hidden, psychic powers, and the occult.
The Moon represents our fears, illusions, the unconscious, imagination, dreams/nightmares, and occult knowledge. It may be an omen of something mysterious, illusive, or intagible – such as hidden messages and/or psychic abilities. The Moon can give rise to creative fantasies and deceptive illusions. “In her hand the bride holds a blood-stained sickle, its Moon-shaped blade a symbol of dark intrigue.”  (Cutting through illusions?)
Astrologically, The Priestess is tied to Cancer (which is ruled by the moon) and the 4th House (home, emotional well-being, family, and feeling “safe”). She is the doorway to our intuition, asking us to look beyond what’s on the surface; beyond the obvious. (As Cancer rules the gut, pay close attention to “gut feelings”.) Signs, dreams, and synchronicities may all play a part in unlocking that door behind which resides a hidden secret. Occult powers may be highlighted.
Together these two Major Arcana cards indicate that there’s more for us to know,
but not right now. All will be revealed in good time.
I love the Seven of Knives (Swords). My Mata Hari. She is tied to the moon in the sign of Aquarius. Here’s where her “Mata Hari” side comes in: The Seven of Knives speaks of deception, deceit, and intrigue. She also hides a secret or surprise, and may presage a premonition. The card may also represent energy-draining people or situations. Hidden motives may be at play.
Again, Major Arcana cards (The Moon and The Priestess) constitute life lessons. The Universe is calling the shots and there’s not a thing we can do about it. The effect of Major Arcana cards can last a long time. The Minor Arcana (Seven of Swords) offer us more in terms of free will. We have options.
