Guru in the 8th house
Jupiter · Ayu Bhava
Guru is the karaka (significator) of wisdom, children, wealth and good fortune. The 8th house, called Ayu Bhava, shows longevity, secrets and sudden events. When Guru sits here, these matters take on its colour.
In the 8th house a benefic protects longevity and brings interest in research and hidden subjects, though its outward results are reduced.
The 8th house is a dusthana (house of difficulty), so results here come through challenges and need conscious handling.
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 8th 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.
