Sun Opposition Mars
You probably have a view that perceives life as a challenge, a fight between yourself and the world for supremacy, and you adopt this combative and assertive stance in an attempt to prove your self-worth. Underlying this attitude is a clashing of inner energies, which are projected out as shadow-adversaries in the external world, so that arguments, dissention and conflict almost seem to follow in your footsteps.
There is little tranquility in your world; it becomes more of a battlefield where you believe you can 'win your spurs' proving your capabilities. You are fired by the competitive spirit, intending to win and be number one, although the quality of your aggressive vibration tends to attract similar people into your life, and this can result in power struggles in working or domestic environments.
Applying extra force may leave you in a position of superiority yet can also increase the number of adversaries that you leave in your wake; your genuine friendships can be few if you act in this manner. You have a powerful desire nature, you easily become fixated on attaining these desires, whether they are lovers, positions of executive status, or whatever, even if your energies are focused only temporarily in such specific directions. These desires can reflect the themes of the houses and signs of Mars and the Sun, and often contain the issues that you feel most combative about.
There can be an aura of 'danger' surrounding you, possibly with a sexual magnetism and aggressive power that some can find extremely attractive, although this energy can overflow through displays of irascible temper and potential violence if uncontrolled. You are very physically responsive and will have a developed visual and sensual appreciation of life. You may have to ensure that your desires do not become compulsive or obsessive in nature. In relationships, you may lack sensitivity to others' feelings and needs, and may need to transform expectations of a partner so that they conform more closely to a realistic appreciation, rather than providing fuel for later disillusionment.
A wise choice of partner is required; otherwise your domestic life could become volatile and traumatic; a partner who evokes your higher nature and qualities is probably more ideal than one who just stimulates your passionate and vigorous nature. Finding a suitable companion, who is strong enough not to allow you to dominate, would probably help in modifying your attitude towards life.
A danger can lie in a tendency to make impulsive decisions or actions, and then regret them later. It may be that experience eventually influences you to make changes in your style of expression, and this may not occur until later in life, perhaps after the age of thirty and through developing maturity. It is to be hoped that there will come a point when you lessen that driving feeling of insecurity and lack of worth, so that you can recognize your real value and potential.
Once that self-imposed pressure to challenge and compete has diminished, and acknowledgement of your performance has been achieved, then new life directions may open. When this occurs take the opportunity to dismantle your combative attitudes, by broadening your world view beyond those limiting tendencies of yours to perceive life in stark black-and-white distinctions. This could develop to include involvements with social causes and pressure groups, where your partisan approach and abundant energies could be put to positive use, providing that you can maintain a balanced perspective on your beliefs and attitudes, and do not attempt a forceful proselytizing or fanatical expression.
