In predictive astrology, Mithuna (Gemini) shows the qualities of quicksilver, a mysterious metal which is highly elusive and susceptible to a wide range of fluctuations. Heat and cold both affect the sign very easily. There is a sparkling quality to it, often brilliant and intuitive. Though it has a great deal of mystic potential, Mithuna's approaches and expressions are basically materialistic. Conflict and instability are important characteristics of the sign. Contentment, satisfaction, stability, and tranquility are not to be found in Mithuna (Gemini). Depression, suicidal tendencies, excitement, experience, and a great thirst for indulgence may arise. These could very well be related to the discovery of the meaning and purpose of life. Mithuna (Gemini) is very active on the subjective plane.
Mithuna (Gemini) is a masculine sign, airy in nature and containing the mixture of movable and fixed qualities which define a common sign. Mithuna (Gemini) is most effective at higher subjective realms, always eager to act and achieve but not terribly effective in yielding concrete results. No planet is exalted or debilitated here and Buddha (Mercury) rules the sign.
