Signs that share the same qualities share many dynamic potentials for growth as well as profound fulfillment, but are often less harmonious.

Quadruplicity Basic Traits
Cardinal Enterprise, Ambition
Fixed Strength, Willpower
Mutable Flexibility, Versatility

Following is a chart specifically listing the actual Signs that are of the same Quadruplicity:

Cardinal Signs: Aries, Cancer, Libra, Capricorn
Fixed Signs: Taurus, Leo, Scorpio, Aquarius
Mutable Signs: Gemini, Virgo, Sagittarius, Pisces

Cardinal Signs: Put together, this is a clear-cut picture of dynamism, activity, tremendous stress, and remarkable achievement. These people know the meaning of great change since their lives are often characterized by significant crises and major successes. This combination is like a simultaneous storm of summer, fall, winter, and spring. The danger is chaotic diffusion of energy; the potential is irrespressible growth and victory. Cardinal Signs = Aries, cancer, Libra and Capricorn.

Fixed Signs: Fixed signs are always establishing themselves in a given place or area of experience. Like explorers who arrive and plant a flag, these people claim a position from which they do not enjoy being deposed. They are staunch, stalwart, upright, trusty, honorable people, although their obstinacy is well-known. Their contribution is fixity, and they are the angels who support our visible world. Fixed Signs = Taurus, Leo, Scorpio, and Aquarius.

Mutable Signs: Mutable people are versatile, sensitive, intelligent, nervous, and deeply curious about life. They are the translators of all energy. They often carry out or complete tasks initiated by others. Combinations of these signs have developed minds; they are imaginative and jumpy and think and talk a lot. At worst their lives are a Tower of Babel. At best they are adaptable and ready creatures who can assimilate one kind of experience and enjoy it while anticipating coming changes. Mutable Signs = Gemini, Virgo, Sagittarius, and Pisces.
