Shani in the 2nd house
Saturn · Dhana Bhava
Shani is the karaka (significator) of discipline, career, endurance and longevity. The 2nd house, called Dhana Bhava, shows wealth, family and speech. When Shani sits here, these matters take on its colour.
In the 2nd house a malefic can make speech sharp and finances uneven, and calls for care in family relations.
The 2nd house is a maraka (sensitive) house as well as a house of resources, so results depend strongly on the graha's dignity.
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 2nd 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.
