The Sun in the Lagna gives a strong sense of self, leadership and pride. Health and vitality are usually good, though the temperament can be hot and impatient; the person likes to be in charge and is noticed easily.
What the 1st house governs
The 1st house, Lagna (self), covers body, health, personality, appearance and the general direction of life. It is a kendra (angular) house, one of the pillars of the chart.
What Sun brings
Surya, the Sun, is the king among the grahas and the natural soul-significator (Atmakaraka). It represents vitality, authority, the father and one's sense of self.
What changes the result
- Sign and dignity: Sun exalted or in its own sign gives the best version of this placement; debilitated or in an enemy sign, the weaker version.
- House lordship: which houses Sun rules for your Lagna decides whose matters it carries into the 1st house.
- Aspects and conjunctions: Jupiter's aspect protects; Saturn, Mars or Rahu add pressure.
- Dasha: the placement shows most strongly during Sun's own Mahadasha or Antardasha (6-year Mahadasha).
