Mars represents our ambition, energy, action and desire. It rules our basic instincts of aggression, anger and survival. There is often no contemplation before action when it comes to this primal energy. All our sexual desires come under Mars. This is the raw physical energy as opposed to the creative energy of the sun. With good Mars placement we are assertive, directed and forthright with bad placement we an be impulsive,rash and aggressive. In your chart, Mars shows your basic animal nature, how you express anger and what gets you angry and more importantly what makes you act.
Mars Opposition Midheaven
This position can have two quite different effects. On one hand, you may be subject to compulsive desires, wanting to do things without any special reason except willfulness. Such actions are usually rash and sudden and may be caused by an inner emotional upheaval. Sometimes this happens because you have had such a stormy and turbulent home life as a young child that all your resentment comes out in sudden aggressive energies. To counter this, your parents should provide you with a reasonably stable and supportive home life, where you can feel that you are accepted for yourself. On the other hand, if you feel confident that your family loves and accepts you, you will experience the energies of this aspect quite differently. You will determine the course of your life very directly, according to your own inner needs and impulses. You will be conscious of these needs, so that you can gratify them in a controlled way instead of being at the mercy of your inner drives. In general, you will succeed by creating a satisfying inner life more than by achieving in ways that the outer world can easily recognize. You may or may not be successful in your career, but that will not be as important to you as inner satisfaction. While you are young, your parents should understand this and help you discover your own needs rather than make you conform to other people's expectations.
