Shani in the 10th house
Saturn · Karma Bhava
Shani is the karaka (significator) of discipline, career, endurance and longevity. The 10th house, called Karma Bhava, shows career, status and karma. When Shani sits here, these matters take on its colour.
In the 10th house a malefic gives ambition, authority and hard-won success in career.
The 10th house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
Shani gives its best results here when it is exalted in Tula, in its own sign (Makara and Kumbha) or in a friendly sign, and when it is not combust.
Results are weaker if Shani is debilitated in Mesha, combust, or afflicted by malefics.
In transit (gochar)
When Shani transits the 10th 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.
