Nakshatra Cluster · Ruling Planet

Jupiter-ruled nakshatras, the 16-year group.

Jupiter rules three of the 27 nakshatras: Punarvasu, Vishakha and Purva Bhadrapada. When the natal Moon falls in any of them, the chart owner opens life in the 16-year Jupiter mahadasha. The macro register is Jupiter's shared karaka signature, modulated by each nakshatra's deity, sign and pada.

The three nakshatras at a glance

Nakshatra	Deity	Range	Symbol
Punarvasu	Aditi	20°00' Gemini to 3°20' Cancer	bow and quiver / return-of-light
Vishakha	Indra-Agni	20°00' Libra to 3°20' Scorpio	triumphal arch
Purva Bhadrapada	Aja Ekapada	20°00' Aquarius to 3°20' Pisces	two-faced man with sword (also front of funeral cot)

What Jupiter rules and how that shapes the group

Jupiter-ruled nakshatras carry the wisdom-and-expansion register: dharmic disposition, principled life-direction, benevolent dignity and the chart owner's relationship to growth and meaning. Jupiter is the karaka for wisdom, dharma, children, father in some readings, wealth and the benevolent-expansion axis. The three Jupiter-ruled nakshatras all sit at sign-boundary positions (20°00'-3°20' arcs straddling two signs), giving them a distinctive cross-sign register that classical practice notes as activating dharmic transitions across the life.

How the three members differ

Punarvasu

Punarvasu runs 20°00' Gemini to 3°20' Cancer. The presiding deity is Aditi, the symbol is the bow and quiver / return-of-light and the register is renewal and return after departure. Read the full reading at Punarvasu nakshatra.

Vishakha

Vishakha runs 20°00' Libra to 3°20' Scorpio. The presiding deity is Indra-Agni, the symbol is the triumphal arch and the register is goal-pursuit and ambition forged in dual-energy. Read the full reading at Vishakha nakshatra.

Purva Bhadrapada

Purva Bhadrapada runs 20°00' Aquarius to 3°20' Pisces. The presiding deity is Aja Ekapada, the symbol is the two-faced man with sword (also front of funeral cot) and the register is fierce dharmic intensity. Read the full reading at Purva Bhadrapada nakshatra.

Moon in any of these three opens the Jupiter mahadasha

The 16-year Jupiter mahadasha activates dharmic, wisdom-axis and growth themes. When the natal Moon falls in Punarvasu, Vishakha or Purva Bhadrapada, the opening Jupiter mahadasha foregrounds the chart's relationship to renewal-wisdom (Punarvasu), ambition-wisdom (Vishakha) or fierce-dharma intensity (Purva Bhadrapada). The cross-sign positions give the Jupiter period a distinctive transitional register during which the chart owner moves between life-phases.

Sub-period activation through the Jupiter period

Inside the 16-year Jupiter mahadasha, the Vimshottari antardasha sequence runs through all 9 planets in proportion to their mahadasha lengths. Each antardasha activates a different karaka pairing with the Jupiter mahalord. Sub-periods of friend-planets to Jupiter read constructively, sub-periods of enemy-planets read more challenging. The full antardasha structure is covered in the Jupiter mahadasha overview.

What this group does not predict

Ruler-group membership reads the macro register of the Jupiter mahadasha and the shared Jupiter karaka signature. It does not generate forward calls by itself. Calibration is by chart and signature class, not by ruler group. The personal-chart reading depends on the Moon's specific nakshatra (Krittika reads differently from Uttara Ashadha), the Moon's pada, the natal house of the Moon, the dispositor's strength and the running transit picture. The framework is explicit about this scope limit.

FAQ

How long is the Jupiter mahadasha in the Vimshottari sequence?

The Jupiter mahadasha runs 16 years. It activates when the natal Moon falls in any of the three Jupiter-ruled nakshatras: Punarvasu, Vishakha or Purva Bhadrapada. The exact degree of the Moon inside the nakshatra fixes how much of the Jupiter mahadasha remains at birth.

What is the shared register of the Jupiter-ruled nakshatras?

All three carry Jupiter's karaka register at the macro level. They then split into distinct readings by sign placement, presiding deity and pada structure. What stays constant is the 16-year mahadasha length and the underlying Jupiter register.

How do the three Jupiter-ruled nakshatras differ?

Punarvasu reads as renewal and return after departure. Vishakha reads as goal-pursuit and ambition forged in dual-energy. Purva Bhadrapada reads as fierce dharmic intensity. All three carry Jupiter's shared register but the deity and sign placement determine which dimension foregrounds in a given chart.

Does the Jupiter-ruled group share a calibrated firing pattern on the corpus?

The three nakshatras share the Jupiter mahadasha length but do not share calibrated forward-call windows automatically. Calibration is by chart and signature class, not by ruler group. The individual nakshatra readings carry calibrated context where it exists.

Where does the Jupiter mahadasha sit in the 120-year cycle?

The Vimshottari mahadasha sequence runs Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17. total 120 years. The Jupiter mahadasha enters the sequence whenever the previous mahadasha closes. The entry point on a personal chart depends entirely on the natal Moon nakshatra and degree.
