As an Astrologer, I synthesize the signs, the symbols, the houses, and the angles. Each planet represents a force in the Universe as well as a psychological urge/force within each person.
CARDINAL (MOVABLE) SIGNS
Aries, Cancer, Libra, Capricorn
The cardinal signs are just like the points on a compass. Aries, east; Libra, west; Cancer, north; Capricorn, south. These 4 signs are called cardinal signs because they are the first signs in each season. Aries, spring; Cancer, summer; Libra, fall; Capricorn, winter. The changes of season are due to the Sun’s “apparent” change of angular distance or, “in reality” , the tilt of the earth according to its location in its orbit.
If you are born in a cardinal sign, you are more than likely versatile, adaptable, and fully capable of adjusting yourself to changing conditions as they occur. Cardinal expresses energy actively and seeks challenges. The basic essence of cardinal signs is survival.
FIXED (FIRM) SIGNS
Taurus, Leo, Scorpio, Aquarius
They are the signs in the middle of each seasonThe fixed signs are associated with the middle of the season. If the cardinal signs bring us into a change of season, then the fixed signs see us firmly centered smack-dab in the middle of those seasons.
If you are born in a fixed sign, you are more than likely set in your ways and more fixed in your views than those born in cardinal or mutable signs. You are likely to have more continuity and be more difficult to sway, change or move from your position. You rarely change your mind and are not so quick to adjust and adapt to new situations.
Fixed expresses itself by wanting to remain stable and secure. The basic essence of fixed signs is growth.
MUTABLE (COMMON OR FLEXED) SIGNS
Gemini, Virgo, Sagittarius, Pisces
They are signs in the last months of each season and assist the energy to change into the cardinal months again. Mutable signs are the last months of the four seasons. The mutable signs finish up with the duties that are common to the season and begin to prepare for the change in the next quarter.
If you are born in a mutable sign, you more than likely have attributes of both the cardinal and fixed signs and can adapt to the nature of both those signs. Incidentally, the cardinal and fixed signs may see you (the mutable sign) as being somewhat unstable, when in reality, you are a chameleon. Mutable expresses itself by wanting to be flexible and adaptable. The basic essence of mutable signs is adaptability.
