The Queen of Disks represents the Watery part of Earth and the function of that element as Mother. She is also "Grandmother River" to certain Native Nations. In the Zodiac She rules from the 21st degree of Sagittarius to the 20th degree of Capricorn and represents the Highest aspect of Passivity/or Magnetic Force in Repose.
There is a lot to interpret on this Thoth Deck Court Card, as she is enthroned on vegetation (magnetic force in repose-- is "Form') and is looking at a river flowing in the background (Her other name) bringing life to the sandy desert. Oasis are springing up along the River's winding path. The Goat standing on a sphere, refers to the dogma of the Great Work as fertility (The expansion and liberation of life.) The Helmet she wears is of coins and/or disks, and upon it are the Great Spiral Horns of the Markhor. Her staff is topped by a Crystal Cube (Three dimensional Hexagram) and in her left curved arm and hand, is the Spiral decorated Disk/shield. Everything in creation is a spiral creation better known a "circles upon circles". All this represents the Ambition of matter to participate in The Great Work and/or Creation.
The Archetype personality (and person) symbolized by this card is endowed with the quiet and serene qualities of power. They are indeed ambitious, as water is ambitious which is to say they calmly go about their work. They have immense wealth of affection, kindness, and greatness of heart. They are not usually intellectual, but instinct and intuition serve their needs just fine. Having the qualities of being, hard working, practical, quite, domesticated they are also unassumingly lustful even to the point of "kinkiness" as they revel in the sensual fertility of their demeanor. This can lead to the Bacchanalian abuse of alcohol and even drugs finding them useful in getting outside themselves and/or the mental servitude of their cultural minds, into the Happy frivolity of surrounding Nature.
When this card is Ill Dignified, they are dull, servile, foolish drudges rather than workers, life for them is purely robotic and they can't seem to rise above their appointed lot.
The general advice of this card is to go forward quietly without overt attacks upon existing situations, i.e. go with the quiet natural flow of your personality in all situations.
As a psycho- physical union, we may notice that just by sitting by a calmly flowing river, we can feel Inner peace flowing through our desert landscape of worry and fear. We become rebalanced and centered again by the Magnetic Flow of the Great Mother. This is the very essence of our Form and brings back the feeling of paradise that form gives Spirit. Grand- Mother River is a great Lover of Being!
