So, lets see what Mars can do in 6th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent -
Mars represents our will power, courage, ability to take actions, aggressive nature, anger, our fighting ability, brother, male friends, a boy friend for a girl, a soldier, an athlete and real estate etc.
6th house is 1st of Dushthana Houses (houses # 6, 8 and 12) and 2nd of Upachaya Houses (houses # 3, 6, 10 & 11). 6th house represents things like diseases, debts, obstacles, enemies, disputes, competitions, litigations, under privileged people, pets, daily routine life, colleagues at work place etc.
So, the Soldier (Mars) has finally reached the place where it wants to be. This is house of Obstacles and Competitions in life, dealing with real tough world outside and Mars energy here wants to conquer anything which is an obstacle. Here in 6th house, they make great Advocates, Surgeons, Soldiers, Athletes and Sports-person. Mars here gives tremendous energy to person to crush all the obstacles in life and move ahead. How come so many different professions? As it is the house of diseases, person can become Doctor or Surgeon, as it is the house of Disputes, person can become Advocate. As it is house of competitions and obstacles, the person can become Sportsman, best example - Sachin Tendulkar.
Aspect wise, Mars 4th aspect goes to 9th house and the person becomes headstrong in his religious views. He is ready to challenge his Gurus and Father and try to over-power the religious beliefs they are teaching him.
Mars next aspect goes to 12th house and these people gain a lot from Foreign Lands. Specially, if they are sportsman, door of foreign lands are always open for them.
Mars next aspect goes to 1st house/Ascendant and brings the great energy and strength in the individual to see through the obstacles of life.
Hope this helps. Next - Mars in 7th house.
