Mangal in the 9th house
Mars · Dharma Bhava
Mangal is the karaka (significator) of energy, courage, siblings and property. The 9th house, called Dharma Bhava, shows luck, dharma, father and higher learning. When Mangal sits here, these matters take on its colour.
In the 9th house a malefic can test faith or relations with father and teachers, and makes one follow one's own path.
The 9th house is a trikona (trine), one of the houses of fortune, which improves whatever graha sits here.
Mangal gives its best results here when it is exalted in Makara, in its own sign (Mesha and Vrishchika) or in a friendly sign, and when it is not combust.
Results are weaker if Mangal is debilitated in Karka, combust, or afflicted by malefics.
In transit (gochar)
When Mangal 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.
