Mars, The Planet of Action
Just as our Venus sign shows us how we love and relate to other people, our Mars sign placement points to our action tendencies, what we like to do, how we are most comfortable expressing our actions and so forth. These actions also include sexuality. The sign it is in will govern how we act, while the house it is in will govern which areas of life we prefer to channel these actions through. For example, someone with a Mars in the 4th house (the house of the home and family) will express actions thourgh family matters, home improvement (or destruction) projects, and things centered around our environment. A person with Mars in the 6th house of health and service, will put their energy into helping others, work, health matters and such. Or they could express it negatively and be that boss who is a tyrant, as this house also rules servants and those who work for us.
