The Sun in the 10th gets directional strength (dig bala) — one of its best positions. It favours authority, government work, leadership roles and a good public reputation.
What the 10th house governs
The 10th house, Karma bhava, covers career, status, authority, reputation and actions in the world. It is an upachaya (growth) house, where results improve with time and effort.
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 10th 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).
