Modalities

Every sign carries two coordinates: an element (what it is made of) and a modality — the mode in which it moves. The three modalities each gather four signs into a grand cross of squares and oppositions, and that tension is the point: these four signs share a style of engagement even as they pull in opposite directions. Cross all three modalities with the four elements and you arrive, uniquely and completely, at all twelve signs — cardinal fire is Aries, and nothing else can be.

Cardinal Modality

The Cardinal modality unites Aries, Cancer, Libra, and Capricorn — the four signs that open each season and embody astrology's purest impulse to initiate.

■

Fixed Modality

The Fixed modality groups Taurus, Leo, Scorpio, and Aquarius — the four signs that hold the middle of each season, embodying persistence, depth, and resistance to change.

Mutable Modality

The mutable modality governs Gemini, Virgo, Sagittarius, and Pisces — the four signs that close each season and master the art of change and adaptation.
