Guru in the 4th house
Jupiter · Sukha Bhava
Guru is the karaka (significator) of wisdom, children, wealth and good fortune. The 4th house, called Sukha Bhava, shows home, mother and happiness. When Guru sits here, these matters take on its colour.
In the 4th house a benefic brings a comfortable home, vehicles, a caring mother and peace of mind.
The 4th house is a kendra (angular house), a pillar of the chart, so a graha here shows its results openly and strongly.
Guru gives its best results here when it is exalted in Karka, in its own sign (Dhanu and Meena) or in a friendly sign, and when it is not combust.
Results are weaker if Guru is debilitated in Makara, combust, or afflicted by malefics.
In transit (gochar)
When Guru transits the 4th 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.
