I was writing an article on astrology and I happened across this site with really nice zodiac descriptions. I'm a Gemini and this is what it said about The Twins.
Ruling House
Gemini is the third Sign of the Zodiac. It is also called the “House of Communication” or, in Vedic Astrology, as the “Place of the Goddess of the Moon”. Just like the ruling house, Geminis love to communicate. But make no mistake about it, Geminis do not just indulge in mindless chatter, the driving force is still the mind.
Geminis are probably the most intellectual of the twelve signs. They are constantly searching for ways to gather information, knowledge or skills. What Geminis also love to do is share the information they have with others, for developing relationships is another of their many traits. It is always fun to be with Geminis because they are bright, quick-witted and the life of any party. Life with a Gemini can never be boring. Truly free spirits, driven by curiosity and a never-ending desire to know, they usually are involved in several activities at once. It is in this kind of chaos, that Geminis thrive.
Another interesting trait inherent to Geminis is their morality. Although self interest is still a primary motivator, Geminis are known to be honest and straightforward. Whatever course of action they choose they do without any measure of deviousness or guile.
Aside from being a house of communication, the Third House also operates on "automatic pilot," meaning, performance of routine tasks can be done without any conscious thought. The house is also associated with siblings, basic education, hand-eye coordination, and manual dexterity.
Ruling Planet
Ruled by the Planet Mercury, Geminis are indeed, mercurial. Like the Roman messenger god, Geminis are quick-thinking, quick-witted and fast on their feet. Geminis are always in constant motion. In social gatherings, Geminis can be seen moving from one group of company to the next. If they are bored, they will start fidgeting and, once again, long for flight.
Ruling Element
Air is Geminis ruling element. Air has been associated with thinking, and those under this sign value intellect over all else. The ability to think clearly and logically, the skill at looking at any project from at least two different perspectives make Geminis an asset to any team. Though not inclined to lead, Geminis make good follower.
Geminis are also capable of bringing this objective reasoning into their personal relationships. Though this approach is sometimes considered cold and emotional, it's what makes Geminis what they are.
Through the influence of Air and Mercury, Geminis will always retain a youthful exuberance and light spirit that will forever make them appear young.
Compatibility
Geminis are most compatible with signs that share their element. Amusing, tolerant and clever Librans will keep Geminis guessing, and the fascinating, ambitious and equally moody Aquarians will be a perfect match to Geminis. Other suitable partners would be Aries and Leo.
Just like the forbidden fruit, Scorpios and Capricorns are irresistible to Geminis. It is important to note, however, that Geminis and these two signs mix perfectly, just like oil and water.
Other Information
The star stone of Gemini is the moss agate, known to be beneficial to Geminis who suffer circulatory problems, and aid in giving their intuitive powers. Geminis are susceptible to diseases of the nervous system and illnesses in the upper body. Thus, Geminis are advised to practice yoga or other exercises that involve deep breathing.
