Nakshatra Cluster · Ruling Planet

Sun-ruled nakshatras, the 6-year group.

Sun rules three of the 27 nakshatras: Krittika, Uttara Phalguni, Uttara Ashadha. All three share the 6-year Sun major period when the natal Moon falls inside them. The macro signature: authority, contract, the lasting form. Sun-ruled nakshatras carry the shortest major period.

The three nakshatras in the group

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	bed legs or fig tree
Uttara Ashadha	Vishvadevas	26°40' Sagittarius to 10°00' Capricorn	elephant tusk

What Sun's ruling register means

Authority, contract, the lasting form. sun-ruled nakshatras carry the shortest major period. Sun-ruled nakshatras inherit this signature at the broad level, then split into three distinct readings by sign placement, presiding deity, and pada structure. The shared element is the 6-year major-period length and the underlying ruling-planet character.

How the three members differ

Krittika

Krittika sits at 26°40' Aries to 10°00' Taurus with deity Agni and symbol the razor or flame. The macro register is cutting, purifying. Read the full deep-dive at Krittika nakshatra.

Uttara Phalguni

Uttara Phalguni sits at 26°40' Leo to 10°00' Virgo with deity Aryaman and symbol the bed legs or fig tree. The macro register is stable union, contract. Read the full deep-dive at Uttara Phalguni nakshatra.

Uttara Ashadha

Uttara Ashadha sits at 26°40' Sagittarius to 10°00' Capricorn with deity Vishvadevas and symbol the elephant tusk. The macro register is lasting victory. Read the full deep-dive at Uttara Ashadha nakshatra.

What the major period looks like

When the natal Moon falls in any of the three Sun-ruled nakshatras, the native opens life in the Sun major period. The 6-year window foregrounds Sun's karaka register. The nakshatra-specific reading further qualifies the period through the presiding deity and sign placement of the natal Moon.

The Vimshottari sub-period sequence inside the Sun major period runs through all 9 planets in proportion to their major-period lengths. Each sub-period activates a different karaka combination. The full sub-period structure is covered in the Sun major-period overview.

What the framework does not predict

The cluster reads structural patterns at the national-chart level and at the cohort level. Group membership does not generate forward calls automatically. Calibration is by chart and signature class. The framework is explicit about this scope limit.

FAQ

How long is the Sun major period in the Vimshottari sequence?

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

What is the macro signature of the Sun-ruled group?

Authority, contract, the lasting form. sun-ruled nakshatras carry the shortest major period. The three nakshatras differ in deity, sign placement, and pada structure, but share the Sun major-period length and the broad ruling-planet register.

How do the three Sun-ruled nakshatras differ?

At the macro level all three carry Sun's register, but each picks up the qualities of its sign placement and presiding deity. Krittika (26°40' Aries to 10°00' Taurus, Agni) reads as cutting, purifying. Uttara Phalguni (26°40' Leo to 10°00' Virgo, Aryaman) reads as stable union, contract. Uttara Ashadha (26°40' Sagittarius to 10°00' Capricorn, Vishvadevas) reads as lasting victory.

Does this group share a major-period firing pattern on the corpus?

The three nakshatras share the Sun major-period length but do not share calibrated forward-call windows automatically. Calibration is by chart and signature class, not by nakshatra group. Individual nakshatra deep-dives carry the calibrated context where it exists.

Where does the Sun-ruled group sit in the 120-year cycle?

In the standard Vimshottari sequence the major-period order is Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, Ketu, Venus, then repeating. The Sun major period therefore enters the sequence whenever the previous major period closes; the entry point on a personal chart depends entirely on the natal Moon nakshatra and degree.
