Surya in the 7th house
Sun · Kalatra Bhava
Surya is the karaka (significator) of soul, father, authority and vitality. The 7th house, called Kalatra Bhava, shows marriage and partnership. When Surya sits here, these matters take on its colour.
In the 7th house a malefic can bring friction or delay in marriage and partnerships, and calls for patience with others.
The 7th house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
Surya gives its best results here when it is exalted in Mesha, in its own sign (Simha) or in a friendly sign, and when it is not combust.
Results are weaker if the Sun is debilitated in Tula or afflicted by Saturn or Rahu.
In transit (gochar)
When Surya transits the 7th house counted from your Moon sign, the period traditionally needs more care.
A single placement is never read alone: sign, aspects, conjunctions, dasha and the whole chart change the outcome.
