Budh in the 7th house
Mercury · Kalatra Bhava
Budh is the karaka (significator) of intellect, speech, business and learning. The 7th house, called Kalatra Bhava, shows marriage and partnership. When Budh sits here, these matters take on its colour.
In the 7th house a benefic supports a good spouse, happy partnerships and success in dealing with the public.
The 7th house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
The 7th house is opposite to where Budh gets directional strength, so it loses some power here.
Budh gives its best results here when it is exalted in Kanya, in its own sign (Mithuna and Kanya) or in a friendly sign, and when it is not combust.
Results are weaker if Budh is debilitated in Meena, combust, or afflicted by malefics.
In transit (gochar)
When Budh 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.
