Guru in the 2nd house
Jupiter · Dhana Bhava
Guru is the karaka (significator) of wisdom, children, wealth and good fortune. The 2nd house, called Dhana Bhava, shows wealth, family and speech. When Guru sits here, these matters take on its colour.
In the 2nd house a benefic supports savings, a sweet and truthful way of speaking, and harmony in the family.
The 2nd house is a maraka (sensitive) house as well as a house of resources, so results depend strongly on the graha's dignity.
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 2nd 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.
