A Mutable Quality is attached to the signs Gemini, Virgo, Sagittarius, and Pisces. The mutable houses are the third, sixth, ninth, and twelfth.
These signs end every season—and have learned the hard lessons taught by spring, summer, fall and winter. They know that all good things come to an end, and their role is to prepare everyone for the changing of seasons. Mutable signs are the adapters of the zodiac, a little bit older and wiser. More flexible and comfortable with change than other signs, they can “chameleon” themselves to fit into a variety of situations. Mutable zodiac signs are also the editors of the zodiac—the ones who complete the package with a winning touch. A plan can be sparked by a Cardinal sign, built by a Fixed sign, then perfected with the critical eye of a Mutable sign.
Mutable signs come at the end of each season. Gemini marks the end of spring, Virgo for summer, Sagittarius for fall, and Pisces at the end of winter.
