What Ketu remedies are for
Ketu remedies are for detachment gone cold — isolation, dissociation, and giving up on things that still matter. Its primary remedy is meditation itself, which is unusual among the grahas.
When it is under strain
An afflicted Ketu reads as sudden loss of interest, confusion about direction, and withdrawal from what one had built. Ganesha and Bhairava worship, feeding dogs, and steady practice are the classical response.
