Nine Grahas, One 120-Year Journey
The life journey in a Vimshottari kundli is nine mahadashas whose years sum to 120: Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, and Mercury 17. Each graha influences the houses it owns and occupies while its period runs, and the antardasha splits that influence by multiplying the two lords' years and dividing by 120. The journey starts at the Moon's nakshatra, not at a Sun sign and not at a digit.
What each graha is allowed to color
The Sun colors authority, the father, and vitality, and he never retrogrades. The Moon colors the mind and the mother. Mars colors courage, land, and conflict, and he aspects the 4th, 7th, and 8th. Mercury colors speech and skill. Jupiter colors children, the guru, and wealth, and he aspects the 5th, 7th, and 9th. Venus colors marriage and agreements. Saturn colors labor and delay, and he aspects the 3rd, 7th, and 10th. Rahu amplifies the house he occupies. Ketu detaches the house he occupies and always sits opposite Rahu. A graha influences a life chapter only when it is the mahadasha or antardasha lord, or when a transit of Saturn or Jupiter strikes the house it has promised. The poster that gives every planet a daily mood skips this gate.
Houses decide the field of influence
Venus in the 10th influences career during Venus's twenty years. Venus in the 7th influences marriage. The same graha does not carry a universal script. The lagna decides which houses he rules. For Mesha, Venus rules the 2nd and the 7th, so his period is money and marriage together, and he is a maraka lord. For Mithuna, Jupiter rules the 7th and the 10th, so Jupiter's sixteen years mix spouse and career. Learning the nine natures without the lagna produces a generic journey. Learning the lagna turns the same nine into a specific one. D9 modifies marriage chapters. D10 modifies career chapters. Both need the birth minute.
The opening balance is the first bend
If the Moon has already crossed most of its nakshatra, the first mahadasha is short and the second lord arrives in childhood. That is why two journeys with the same rising sign diverge immediately. Jyothish SI computes the balance from the Lahiri Moon after the city sets the zone offset. A free account can cast the kundli and chat about the lord now running. The influence people feel this year is that lord's houses, plus the antardasha lord's houses, not the full chorus of nine. Ask for the two lords. Leave the other seven for their own years.
Frequently asked questions
Do the nine mahadashas cover a fixed span?
They sum to 120 years: 7, 20, 6, 10, 7, 18, 16, 19, and 17. The birth balance uses only the remaining fraction of the Moon's nakshatra.
When does a graha influence events?
When it is mahadasha or antardasha lord, through the houses it owns, occupies, and aspects. Transits of Saturn and Jupiter can trigger a house the dasha has already promised.
Does every lagna give Venus the same journey?
No. Venus always karakas marriage, but the houses he rules depend on the lagna. For Aries he rules the 2nd and 7th. For another lagna he may rule the 10th.
