The Rahu Mahadasha for Virgo Ascendant
18 years · Rahu rules no house
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Virgo ascendant Rahu holds none: the nodes rule no sign in whole-sign lordship, so the 18-year Rahu mahadasha for Virgo is read through the lord of the sign Rahu occupies at birth, and through that sign’s house from Virgo, which no table can supply without the chart.
Rahu is exalted on the commoner reckoning in Taurus, the 9th from Virgo, and debilitated by the same reckoning in Scorpio, the 3rd; planets.js records other signs as well. Rahu counts Mercury, Virgo’s lagna lord, a friend; Mercury’s own row names no node, so the reverse has no entry. Rahu’s own nakshatras fall in Ardra (the 10th), Swati (the 2nd) and Shatabhisha (the 6th) for Virgo ascendant, which is where a birth that opens in the Rahu mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Virgo
| # | Antardasha | Length (classical) | Its lord rules, for Virgo |
|---|---|---|---|
| 1 | Rahu–Rahu | 2 years 8 months 12 days | no house |
| 2 | Rahu–Jupiter | 2 years 4 months 24 days | the 4th and the 7th |
| 3 | Rahu–Saturn | 2 years 10 months 6 days | the 5th and the 6th |
| 4 | Rahu–Mercury | 2 years 6 months 18 days | the 1st and the 10th |
| 5 | Rahu–Ketu | 1 year 18 days | no house |
| 6 | Rahu–Venus | 3 years | the 2nd and the 9th |
| 7 | Rahu–Sun | 10 months 24 days | the 12th |
| 8 | Rahu–Moon | 1 year 6 months | the 11th |
| 9 | Rahu–Mars | 1 year 18 days | the 3rd and the 8th |
For Virgo ascendant, three of the Rahu mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Rahu–Saturn, Rahu–Sun and Rahu–Mars, and two to lords of a trikona other than the 1st: Rahu–Saturn and Rahu–Venus. The sub-period of Mercury, Virgo’s lagna lord, is Rahu–Mercury, the fourth of nine, 2 years 6 months 18 days long. Counted in time, sub-periods whose lords hold a dusthana for Virgo take 4 years 9 months 18 days (27%) of the Rahu mahadasha’s 18 years, and those whose lords hold a trikona other than the 1st take 5 years 10 months 6 days (32%); a lord holding both is counted in both. In the Rahu mahadasha for Virgo, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For a Virgo-rising chart this is the frame of the Rahu mahadasha, not a forecast: where Rahu and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
