The Three Modalities
The three modalities describe a sign’s posture toward change, by where it sits in its season.
- Cardinal
- The cardinal signs open each season: the initiating ones, better at the first move than at the long middle.
- Fixed
- The fixed signs hold the middle of each season: the sustaining ones, hard to start and harder to divert.
- Mutable
- The mutable signs close each season: the adapting ones, at ease with a plan that changes and less so with one that does not.
