There are 12 astrological signs. The twelve signs of the Zodiac are each divided into several sets of groups, or numbers. They are divided into two's (dualities), three's (triplicities), four's,(quadruplicities) and six's (polarities).
The twelve zodiac signs are each divided ino two groups: Masculine and Feminine. Six signs are masculine and six of the signs are feminine. This is known as the signs Duality. This is not to be confused with the literal (and more sexist) veiw of masculine/feminine. A "feminine" sign is not any more "feminine" in the literal terms than a "masculine" sign, and vice versa. Everyone has both masculine and feminine qualities, but the astrological distinctions made here with the signs Duality, meerly is a symbollic expression of the sign, and how it experiences itself to find balance with the opposite energetic expression.
Masculine Signs are direct and energetic. These signs are outer-directed and find their strength through direct action.
Feminine Signs are receptive and magnetic. These signs are self-contained and find their strength through inner reserves.
The 6 signs with the Masculine Duality are: ARIES, GEMINI, LEO, LIBRA, SAGITTARIUS, and AQUARIUS
The 6 signs with the Feminine Duality are: TAURUS, CANCER, VIRGO, SCORPIO, CAPRICORN, and PISCES.
The twelve zodiac signs are each divided ino four groups containing three signs each. Each of these groups of 3 are called Triplicities, and each one is associated with a particular Element. The four elements are: Earth - Air - Fire - Water. In Astrology, an element symbolized a fundamental characterization of the sign. Each elemental group will express energies or personality traits that represent one of these basic four elements.
The 3 FIRE Signs are: ARIES, LEO, and SAGITTARIUS.
Fire Signs are Active and Enthusiastic.
The 3 EARTH Signs are: TAURUS, VIRGO, and CAPRICORN
Earth Signs are Practical and Stable.
The 3 AIR Signs are: GEMINI, LIBRA, and AQUARIUS
Air Signs are Intellectual and Communicative.
The 3 WATER Signs are: CANCER, SCORPIO, and PISCES.
Water Signs are Emotional and Intuitive.
The twelve zodiac signs are each divided ino three groups containing four signs each. Each four-sign group is called a quadruplicity, and each one represents a quality. The three astrological qualities are: Cardinal, Fixed, and Mutable. The quality of a sign signifies its interaction with the outside world. It's "outer self expression".
Each astrological sign has a unique combination of Duality (energy), Triplicity (Element) and Quadruplicity (quality).
Not one signs shares a similar combination. Because each sign is unique in this way, each sign will express the characteristics of its quality, element, and duality differently.
ARIES: Masculine - Fire - Cardinal
TAURUS: Feminine - Earth - Fixed
GEMINI : Masculine - Air - Mutable
CANCER: Feminine - Water - Cardinal
LEO: Masculine - Fire - Fixed
VIRGO: Feminine - Earth - Mutable
LIBRA: Masculine - Air - Cardinal
SCORPIO: Feminine - Water - Fixed
SAGITTARIUS: Masculine - Fire - Mutable
CAPRICORN: Feminine - Earth - Cardinal
AQUARIUS: Masculine - Air - Fixed
PISCES: Feminine - Water - Mutable
The twelve signs of the zodiac are also divided into six groups containing two signs each. Each 2-sign group is called a Polarity (which means "opposite"). So each zodiac sign has an opposite sign in the other half of the zodiac. The two signs express opposite characteristics from one another.
Each astrological sign would do well in learning the qualities and characteristics of its opposite sign (polarity).
Learning to balance these opposite energies will bring the personality and expression more into balance and harmony.
