The positions of Mars in 12th house in the annual chart works like a ‘Mahavat’, the one who drives the elephant. This position of Mars makes the native capable to take control over aggressive nature of Mars & Rahu. If Rahu is malefic in the chart its auspiciousness is being controlled by Mars positioned in 12th house in the same way as a crazy elephant is being controlled by Mahavat. Inauspicious events will not happen in life, there will be revolutionary ideas in mind in all areas of life. One will be more courageous and brave. There will be gains through travels in that year.
But Mars if either aspected or conjuncted with malefic planets will no more be so auspicious; it gets afflicted & spoils marital life. There may be situation of divorce. False allegations will be imposed on native. Physical injury, imprisonment too may be faced in that year. The native will spoil his/ her works by stupid actions. One may have to make many visits to the court.
To ward off the negative influence of malefic Mars one must do some remedies and take some precautions.
