The Venus Mahadasha for Sagittarius Ascendant
20 years · Venus rules the 6th and 11th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Sagittarius ascendant Venus rules the 6th (Taurus) and the 11th (Libra), so for Sagittarius the 20-year Venus mahadasha carries both a dusthana and an upachaya house and an upachaya house.
Counted from Sagittarius, Venus is exalted in the 4th (Pisces) and debilitated in the 10th (Virgo). Jupiter, Sagittarius’s lagna lord, counts Venus an enemy; Venus counts Jupiter neutral. Venus’s own nakshatras fall in Bharani (the 5th), Purva Phalguni (the 9th) and Purva Ashadha (the 1st) for Sagittarius ascendant, which is where a birth that opens in the Venus mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Sagittarius
| # | Antardasha | Length (classical) | Its lord rules, for Sagittarius |
|---|---|---|---|
| 1 | Venus–Venus | 3 years 4 months | the 6th and the 11th |
| 2 | Venus–Sun | 1 year | the 9th |
| 3 | Venus–Moon | 1 year 8 months | the 8th |
| 4 | Venus–Mars | 1 year 2 months | the 5th and the 12th |
| 5 | Venus–Rahu | 3 years | no house |
| 6 | Venus–Jupiter | 2 years 8 months | the 1st and the 4th |
| 7 | Venus–Saturn | 3 years 2 months | the 2nd and the 3rd |
| 8 | Venus–Mercury | 2 years 10 months | the 7th and the 10th |
| 9 | Venus–Ketu | 1 year 2 months | no house |
For Sagittarius ascendant, three of the Venus mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Venus–Venus, Venus–Moon and Venus–Mars, and two to lords of a trikona other than the 1st: Venus–Sun and Venus–Mars. The sub-period of Jupiter, Sagittarius’s lagna lord, is Venus–Jupiter, the sixth of nine, 2 years 8 months long. Counted in time, sub-periods whose lords hold a dusthana for Sagittarius take 6 years 2 months (31%) of the Venus mahadasha’s 20 years, and those whose lords hold a trikona other than the 1st take 2 years 2 months (11%); a lord holding both is counted in both. In the Venus mahadasha for Sagittarius, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For a Sagittarius-rising chart this is the frame of the Venus mahadasha, not a forecast: where Venus and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
