Planets in houses · Kendra
Chandra in the 1st house
Moon · Tanu Bhava
Chandra is the karaka (significator) of mind, mother, emotions and peace. The 1st house, called Tanu Bhava, shows self, body and personality. When Chandra sits here, these matters take on its colour.
A benefic in the Lagna is a blessing: it gives a pleasant nature, good health and a likeable personality, and protects the whole chart.
The 1st house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
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 1st house counted from your Moon sign, the period is traditionally favourable.
A single placement is never read alone: sign, aspects, conjunctions, dasha and the whole chart change the outcome.
