The Venus Mahadasha for Gemini Ascendant
20 years · Venus rules the 5th and 12th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Gemini ascendant Venus rules the 5th (Libra) and the 12th (Taurus), so for Gemini the 20-year Venus mahadasha carries both a trikona house and a dusthana house.
Counted from Gemini, Venus is exalted in the 10th (Pisces) and debilitated in the 4th (Virgo). Mercury, Gemini’s lagna lord, and Venus count each other a friend. Venus’s own nakshatras fall in Bharani (the 11th), Purva Phalguni (the 3rd) and Purva Ashadha (the 7th) for Gemini ascendant, which is where a birth that opens in the Venus mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Gemini
| # | Antardasha | Length (classical) | Its lord rules, for Gemini |
|---|---|---|---|
| 1 | Venus–Venus | 3 years 4 months | the 5th and the 12th |
| 2 | Venus–Sun | 1 year | the 3rd |
| 3 | Venus–Moon | 1 year 8 months | the 2nd |
| 4 | Venus–Mars | 1 year 2 months | the 6th and the 11th |
| 5 | Venus–Rahu | 3 years | no house |
| 6 | Venus–Jupiter | 2 years 8 months | the 7th and the 10th |
| 7 | Venus–Saturn | 3 years 2 months | the 8th and the 9th |
| 8 | Venus–Mercury | 2 years 10 months | the 1st and the 4th |
| 9 | Venus–Ketu | 1 year 2 months | no house |
For Gemini ascendant, three of the Venus mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Venus–Venus, Venus–Mars and Venus–Saturn, and two to lords of a trikona other than the 1st: Venus–Venus and Venus–Saturn. The sub-period of Mercury, Gemini’s lagna lord, is Venus–Mercury, the eighth of nine, 2 years 10 months long. Counted in time, sub-periods whose lords hold a dusthana for Gemini take 7 years 8 months (38%) of the Venus mahadasha’s 20 years, and those whose lords hold a trikona other than the 1st take 6 years 6 months (33%); a lord holding both is counted in both. In the Venus mahadasha for Gemini, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For a Gemini-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.
