Nakshatra Cluster · Ruling Planet

Sun-ruled nakshatras, the 6-year group.

Sun rules three of the 27 nakshatras: Krittika, Uttara Phalguni and Uttara Ashadha. When the natal Moon falls in any of them, the chart owner opens life in the 6-year Sun mahadasha. The macro register is Sun's shared karaka signature, modulated by each nakshatra's deity, sign and pada.

The three nakshatras at a glance

Nakshatra	Deity	Range	Symbol
Krittika	Agni	26°40' Aries to 10°00' Taurus	razor or flame
Uttara Phalguni	Aryaman	26°40' Leo to 10°00' Virgo	hammock back / fig tree
Uttara Ashadha	Vishvadevas	26°40' Sagittarius to 10°00' Capricorn	elephant tusk

What Sun rules and how that shapes the group

Sun-ruled nakshatras carry the authority register: leadership, dharmic-public role, dignified recognition and the lasting forms that institutional life produces. The Sun is the karaka for the soul (atmakaraka in Jaimini), authority, the father, leadership, dignity and the heart. The three Sun-ruled nakshatras inherit this register and modulate it through their distinct presiding deities, sign positions and symbolic registers.

How the three members differ

Krittika

Krittika runs 26°40' Aries to 10°00' Taurus. The presiding deity is Agni, the symbol is the razor or flame and the register is cutting discernment and purifying fire. Read the full reading at Krittika nakshatra.

Uttara Phalguni

Uttara Phalguni runs 26°40' Leo to 10°00' Virgo. The presiding deity is Aryaman, the symbol is the hammock back / fig tree and the register is stable union and contract-keeping. Read the full reading at Uttara Phalguni nakshatra.

Uttara Ashadha

Uttara Ashadha runs 26°40' Sagittarius to 10°00' Capricorn. The presiding deity is Vishvadevas, the symbol is the elephant tusk and the register is sustained victory and lasting recognition. Read the full reading at Uttara Ashadha nakshatra.

Moon in any of these three opens the Sun mahadasha

The 6-year Sun mahadasha is the shortest of the nine Vimshottari periods. When the natal Moon falls in Krittika, Uttara Phalguni or Uttara Ashadha, the chart owner opens life in the Sun mahadasha. a window of dignified-recognition and authority-formation themes weighted by the specific nakshatra-deity register. Sun mahadasha through Krittika reads as discerning leadership and decisive purification; through Uttara Phalguni reads as dharmic-contract dignity; through Uttara Ashadha reads as sustained-victory recognition that endures.

Sub-period activation through the Sun period

Inside the 6-year Sun 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 Sun mahalord. Sub-periods of friend-planets to Sun read constructively, sub-periods of enemy-planets read more challenging. The full antardasha structure is covered in the Sun mahadasha overview.

What this group does not predict

Ruler-group membership reads the macro register of the Sun mahadasha and the shared Sun 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 Sun mahadasha in the Vimshottari sequence?

The Sun mahadasha runs 6 years. It activates when the natal Moon falls in any of the three Sun-ruled nakshatras: Krittika, Uttara Phalguni or Uttara Ashadha. The exact degree of the Moon inside the nakshatra fixes how much of the Sun mahadasha remains at birth.

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

All three carry Sun'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 6-year mahadasha length and the underlying Sun register.

How do the three Sun-ruled nakshatras differ?

Krittika reads as cutting discernment and purifying fire. Uttara Phalguni reads as stable union and contract-keeping. Uttara Ashadha reads as sustained victory and lasting recognition. All three carry Sun's shared register but the deity and sign placement determine which dimension foregrounds in a given chart.

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

The three nakshatras share the Sun 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 Sun 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 Sun 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.
