Budh in the 4th house
Mercury · Sukha Bhava
Budh is the karaka (significator) of intellect, speech, business and learning. The 4th house, called Sukha Bhava, shows home, mother and happiness. When Budh sits here, these matters take on its colour.
In the 4th house a benefic brings a comfortable home, vehicles, a caring mother and peace of mind.
The 4th 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 4th 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.
