Planets in houses · Dusthana
Chandra in the 12th house
Moon · Vyaya Bhava
Chandra is the karaka (significator) of mind, mother, emotions and peace. The 12th house, called Vyaya Bhava, shows expenses, foreign lands and moksha. When Chandra sits here, these matters take on its colour.
In the 12th house a benefic turns spending toward good causes and supports sleep, spiritual life and foreign connections.
The 12th house is a dusthana (house of difficulty), so results here come through challenges and need conscious handling.
Chandra gives its best results here when it is exalted in Vrishabha, in its own sign (Karka) or in a friendly sign, and when it is not combust.
Results are weaker if Chandra is debilitated in Vrishchika, combust, or afflicted by malefics.
In transit (gochar)
When Chandra transits the 12th 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.
