The Three Modalities
The element says what a sign is made of. The modality says how it moves. There are three, and each one appears four times around the zodiac, once in every element.
- Cardinal: starts Aries, Cancer, Libra, Capricorn
- Fixed: sustains Taurus, Leo, Scorpio, Aquarius
- Mutable: adapts Gemini, Virgo, Sagittarius, Pisces
The modalities come from the seasons. The zodiac begins at the spring equinox, and each season spans three signs.
- Cardinal signs (Aries, Cancer, Libra, Capricorn) open a season: the equinoxes and the solstices. They start things.
- Fixed signs (Taurus, Leo, Scorpio, Aquarius) hold the middle of a season, when it is at its fullest. They sustain things.
- Mutable signs (Gemini, Virgo, Sagittarius, Pisces) close a season and prepare the next. They adapt.
Signs of the same modality sit 90 or 180 degrees apart, in square or in opposition. That is why they understand each other's drive and still rub against each other: they want the same kind of thing in four different ways.
