The Moon Mahadasha for Libra Ascendant
10 years · Moon rules the 10th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Libra ascendant the Moon rules only the 10th (Cancer), a kendra and an upachaya house, so for Libra the 10-year Moon mahadasha carries a single lordship.
Counted from Libra, the Moon is exalted in the 8th (Taurus) and debilitated in the 2nd (Scorpio). Venus, Libra’s lagna lord, counts the Moon an enemy; the Moon counts Venus neutral. The Moon’s own nakshatras fall in Rohini (the 8th), Hasta (the 12th) and Shravana (the 4th) for Libra ascendant, which is where a birth that opens in the Moon mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Libra
| # | Antardasha | Length (classical) | Its lord rules, for Libra |
|---|---|---|---|
| 1 | Moon–Moon | 10 months | the 10th |
| 2 | Moon–Mars | 7 months | the 2nd and the 7th |
| 3 | Moon–Rahu | 1 year 6 months | no house |
| 4 | Moon–Jupiter | 1 year 4 months | the 3rd and the 6th |
| 5 | Moon–Saturn | 1 year 7 months | the 4th and the 5th |
| 6 | Moon–Mercury | 1 year 5 months | the 9th and the 12th |
| 7 | Moon–Ketu | 7 months | no house |
| 8 | Moon–Venus | 1 year 8 months | the 1st and the 8th |
| 9 | Moon–Sun | 6 months | the 11th |
For Libra ascendant, three of the Moon mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Moon–Jupiter, Moon–Mercury and Moon–Venus, and two to lords of a trikona other than the 1st: Moon–Saturn and Moon–Mercury. The sub-period of Venus, Libra’s lagna lord, is Moon–Venus, the eighth of nine, 1 year 8 months long. Counted in time, sub-periods whose lords hold a dusthana for Libra take 4 years 5 months (44%) of the Moon mahadasha’s 10 years, and those whose lords hold a trikona other than the 1st take 3 years (30%); a lord holding both is counted in both. In the Moon mahadasha for Libra, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For a Libra-rising chart this is the frame of the Moon mahadasha, not a forecast: where the Moon and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
