from Timing Events Through Vimshottari Dasha - ch 7
What must have remained towards the end of the Jupiter period (Jupiter-Rahu dasha) is an undistinguished [career] record. See it in three ways:
From the debilitated Jupiter in the birth horoscope, Rahu is in the 10th house with the 6th and 8th lord, though Mercury here as the 9th lord could have prevented the ruination of his career.
In the navamsha, Rahu is being aspected by the 8th and 12th lord from Jupiter.
In the dashamsha, Rahu is with the 8th and 12th lords in the 3rd house, hardly good for rise in career.
