Ketu in the 11th house
South node · Labha Bhava
Ketu is the karaka (significator) of detachment, intuition, spirituality and past karma. The 11th house, called Labha Bhava, shows gains, income and friends. When Ketu sits here, these matters take on its colour.
In the 11th house a malefic is strong: it brings gains, fulfilment of desires and influential contacts.
The 11th house is an upachaya (house of growth): results improve steadily with time and effort.
Ketu is a shadow graha and gives the results of the sign lord and conjunct grahas; it is considered strong in Vrishchika.
Results are weaker if Ketu is debilitated in Vrishabha, combust, or afflicted by malefics.
In transit (gochar)
When Ketu transits the 11th 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.
