Ketu in the 5th house
South node · Putra Bhava
Ketu is the karaka (significator) of detachment, intuition, spirituality and past karma. The 5th house, called Putra Bhava, shows children, intelligence and creativity. When Ketu sits here, these matters take on its colour.
In the 5th house a malefic can delay children or unsettle the mind, while giving a sharp, practical intelligence.
The 5th house is a trikona (trine), one of the houses of fortune, which improves whatever graha sits here.
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 5th 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.
