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 Square Saturn
With Mars Square Saturn you can be austere, callous and harsh and usually won't go out of your way to help others unless you gain by it. Your actions are frequently frustrated, leading to negativity and resentment and you must overcome these. Conflict and hardship will transform your consciousness and redeem your past, and willingness to take discipline will set your soul free. You can be physically violent (or a victim of the same) or suffer an early loss of a parent. You may also experience physical hardship, broken bones and accidents, often in the workplace where harsh, dirty or even dangerous conditions exist, possibly even resulting in your death. You have health problems related to the signs of Mars and Saturn. You have difficulty relating to others, especially in partnerships and marriage, and are apt to make enemies due to your lack of gentleness, patience and kindness. You must become loving and compassionate instead of passing judgment or criticizing. Since you alternate between aggression and apathy, you may be severely restricted in your career, which often involves politics or the military. Your actions are not well regulated or properly directed and you lack a sense of sustained purpose. You often fail to follow through on projects you start, often gaining a reputation for being lazy or unreliable.
