The sign of Gemini is ruled by the planet Mercury. Physically it is related to the hands and lungs. It is said to have a masculine nature, and is therefore more outwardly oriented in its energy expression. It is an Air sign, and this means that it is connected with communication, mental contact and social principles. It is also a Mutable sign which enhances flexibility and adaptability. Planets placed in this sign will often reflect on personal intelligence, bringing a tremendous curiosity and a need to exchange ideas with other people in a social environment.

Negative manifestations of Gemini influences are a flightiness and unreliability, and a tendency to get involved with too many things at any one time. There is a love of ideas, but no inner need to put them into practice. Nevertheless this influence confers great mental insight, though there is often some kind of split in connection with planets placed in this sign. Planets here manifest considerable versatility and mental skills in regard to all forms of communication.

The greatest challenges come for you when communication problems arise. Often an important break with a brother, sister or close friend can inaugurate a complete mental revaluation. In your essential search for meaning you can feel a bond to two very different schools of thought, or you can have two mentors with quite different ideas. Variety and polarity is the stuff of life for you, and you feel distinctly uncomfortable if you are asked to identify yourself with one single direction or opinion. Tension can arise in partnership matters because of your changeability and seeming inconstancy. Often it is enough for you to entertain fleeting ideas as a kind of mental gymnastics. Thus frustration arises in others because you don't always act on your ideas. Nevertheless you are fun to be with; you rarely take yourself too seriously, and are always willing to adapt to change.
