Ketu in the 6th house
South node · Ripu Bhava
Ketu is the karaka (significator) of detachment, intuition, spirituality and past karma. The 6th house, called Ripu Bhava, shows enemies, debts, health and service. When Ketu sits here, these matters take on its colour.
In the 6th house a malefic is welcome: it defeats enemies, clears debts and gives the stamina to compete.
The 6th house is a dusthana (house of difficulty), so results here come through challenges and need conscious handling.
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 6th 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.
