The Saturn Mahadasha for Gemini Ascendant
19 years · Saturn rules the 8th and 9th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Gemini ascendant Saturn rules the 8th (Capricorn) and the 9th (Aquarius), so for Gemini the 19-year Saturn mahadasha carries both a dusthana house and a trikona house.
Counted from Gemini, Saturn is exalted in the 5th (Libra) and debilitated in the 11th (Aries). Mercury, Gemini’s lagna lord, counts Saturn neutral; Saturn counts Mercury a friend. Saturn’s own nakshatras fall in Pushya (the 2nd), Anuradha (the 6th) and Uttara Bhadrapada (the 10th) for Gemini ascendant, which is where a birth that opens in the Saturn mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Gemini
| # | Antardasha | Length (classical) | Its lord rules, for Gemini |
|---|---|---|---|
| 1 | Saturn–Saturn | 3 years 3 days | the 8th and the 9th |
| 2 | Saturn–Mercury | 2 years 8 months 9 days | the 1st and the 4th |
| 3 | Saturn–Ketu | 1 year 1 month 9 days | no house |
| 4 | Saturn–Venus | 3 years 2 months | the 5th and the 12th |
| 5 | Saturn–Sun | 11 months 12 days | the 3rd |
| 6 | Saturn–Moon | 1 year 7 months | the 2nd |
| 7 | Saturn–Mars | 1 year 1 month 9 days | the 6th and the 11th |
| 8 | Saturn–Rahu | 2 years 10 months 6 days | no house |
| 9 | Saturn–Jupiter | 2 years 6 months 12 days | the 7th and the 10th |
For Gemini ascendant, three of the Saturn mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Saturn–Saturn, Saturn–Venus and Saturn–Mars, and two to lords of a trikona other than the 1st: Saturn–Saturn and Saturn–Venus. The sub-period of Mercury, Gemini’s lagna lord, is Saturn–Mercury, the second of nine, 2 years 8 months 9 days long. Counted in time, sub-periods whose lords hold a dusthana for Gemini take 7 years 3 months 12 days (38%) of the Saturn mahadasha’s 19 years, and those whose lords hold a trikona other than the 1st take 6 years 2 months 3 days (33%); a lord holding both is counted in both. In the Saturn 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 Saturn mahadasha, not a forecast: where Saturn and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
