Budh in the 9th house
Mercury · Dharma Bhava
Budh is the karaka (significator) of intellect, speech, business and learning. The 9th house, called Dharma Bhava, shows luck, dharma, father and higher learning. When Budh sits here, these matters take on its colour.
In the 9th house a benefic is very fortunate: it brings luck, faith, higher learning and support from father and teachers.
The 9th house is a trikona (trine), one of the houses of fortune, which improves whatever graha sits 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 9th 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.
