Budh in the 10th house
Mercury · Karma Bhava
Budh is the karaka (significator) of intellect, speech, business and learning. The 10th house, called Karma Bhava, shows career, status and karma. When Budh sits here, these matters take on its colour.
In the 10th house a benefic brings respect, ethical work and a good name in one's career.
The 10th house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
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 10th house counted from your Moon sign, the period is traditionally favourable.
A single placement is never read alone: sign, aspects, conjunctions, dasha and the whole chart change the outcome.
