Tribhagi Vimshottari Dasa

Dasa Periods

Each Vimshottari mahadasa is divided by 3. The cycle of 9 planets totals 40 years; running it three times covers 120 years.

Calculation Notes

• Starting nakshatra is the same as in standard Vimshottari — the nakshatra of the Moon at birth. Aswini is ruled by Ketu, so Ketu is the first dasa for an Aswini-born native; Moola and Magha are also ruled by Ketu and produce the same starting dasa.
• Because each lord's stretch is one-third the size, the same nine dasas come around three times in a normal lifetime — once roughly every 40 years.
• In JHora: Dasas → Vimsottari Dasa → Variations → Tribhagi.
• Use Tribhagi in addition to standard Vimshottari, never as a replacement. It is a confirmation overlay.
• Primarily applied to Rasi (D-1); secondarily to Navamsa (D-9). It is described as "very physical and mundane" — well suited to material events that have a clear visible trigger.

Reading with Progressed Moon

The technique pairs naturally with the progressed Moon. Read the running Tribhagi dasa as the broad period; then use the progressed Moon's position to pinpoint events within the dasa:

1. Take the dasa lord and the nakshatra it rules within the cycle.
2. Locate that nakshatra in the chart by its degrees (each pada is 3°20').
3. Sub-divide the dasa period across the nakshatra's padas — each pada gets an equal share of the dasa.
4. Note which house each pada lands in and which special lagnas (AL, UL, GL, SL) and sahamas the progressed Moon contacts in that span.

Sahamas to Cross-Check

The lessons specifically call out which sahamas to use and how to read them:

• Event sahamas: Jalapatana, Labha — fire on a single contact by the progressed Moon.
• Duration sahamas: Jada, Roga — produce a sustained period of effect when the Moon arrives.
• Yasas Sahama activated by Moon → recognition.
• Roga Sahama end of Revathi → triggered illness window in PVR's worked 1983–84 example.
