from Timing Events Through Vimshottari Dasha - ch 7
Now in the next dasha (mahadasha) of Saturn aspected by Mars, the 12th lord in the horoscope, shows some controversy, bad confidential reports or lack lustre performance as a result of which he would be overlooked for an important promotion if it became due.
Then Saturn in the navamsha with the 12th lord aspected by the 6th lord Jupiter does show an impediment in his career.
In the dashamsha, Saturn as the 10th lord opposed by the Sun from the 8th house and the 8th lord Mars aspecting the 10th house must mean his being overlooked for an important promotion.
