The Jupiter Mahadasha for Scorpio Ascendant
16 years · Jupiter rules the 2nd and 5th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Scorpio ascendant Jupiter rules the 2nd (Sagittarius) and the 5th (Pisces), so for Scorpio the 16-year Jupiter mahadasha carries both an unclassed house and a trikona house.
Counted from Scorpio, Jupiter is exalted in the 9th (Cancer) and debilitated in the 3rd (Capricorn). Mars, Scorpio’s lagna lord, and Jupiter count each other a friend. Jupiter’s own nakshatras fall in Punarvasu (the 8th and 9th), Vishakha (the 12th and 1st) and Purva Bhadrapada (the 4th and 5th) for Scorpio ascendant, which is where a birth that opens in the Jupiter mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Scorpio
| # | Antardasha | Length (classical) | Its lord rules, for Scorpio |
|---|---|---|---|
| 1 | Jupiter–Jupiter | 2 years 1 month 18 days | the 2nd and the 5th |
| 2 | Jupiter–Saturn | 2 years 6 months 12 days | the 3rd and the 4th |
| 3 | Jupiter–Mercury | 2 years 3 months 6 days | the 8th and the 11th |
| 4 | Jupiter–Ketu | 11 months 6 days | no house |
| 5 | Jupiter–Venus | 2 years 8 months | the 7th and the 12th |
| 6 | Jupiter–Sun | 9 months 18 days | the 10th |
| 7 | Jupiter–Moon | 1 year 4 months | the 9th |
| 8 | Jupiter–Mars | 11 months 6 days | the 1st and the 6th |
| 9 | Jupiter–Rahu | 2 years 4 months 24 days | no house |
For Scorpio ascendant, three of the Jupiter mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Jupiter–Mercury, Jupiter–Venus and Jupiter–Mars, and two to lords of a trikona other than the 1st: Jupiter–Jupiter and Jupiter–Moon. The sub-period of Mars, Scorpio’s lagna lord, is Jupiter–Mars, the eighth of nine, 11 months 6 days long. Counted in time, sub-periods whose lords hold a dusthana for Scorpio take 5 years 10 months 12 days (37%) of the Jupiter mahadasha’s 16 years, and those whose lords hold a trikona other than the 1st take 3 years 5 months 18 days (22%); a lord holding both is counted in both. In the Jupiter mahadasha for Scorpio, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For a Scorpio-rising chart this is the frame of the Jupiter mahadasha, not a forecast: where Jupiter and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
