ಕೇತು remedies are kept on ಮಂಗಲವಾರ: chant ಸ್ರಾಂ ಸ್ರೀಂ ಸ್ರೌಂ ಸಃ ಕೇತವೇ ನಮಃ, donate ರಂಗ-ಬಿರಂಗಾ ವಸ್ತ್ರ, ಕಾಲೇ ತಿಲ, and keep the weekday fast. ಲಹಸುನಿಯಾ is the graha's stone, but it should only be worn once ಕೇತು has been established as a functional benefic for your lagna.
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.
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.
The mantra, the weekday fast and the charity are safe for anyone — they address ಕೇತು without amplifying it. ಲಹಸುನಿಯಾ is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
ಮಂಗಲವಾರ. Fasting, charity and mantra japa for ಕೇತು all belong to that day.
The classical Sankhya is 17,000 repetitions, completed over weeks rather than at once. Begin with one mala — 108 — a day and build up; sincerity matters more than arithmetic.
Most charts should not wear ಲಹಸುನಿಯಾ at all. It is prescribed only where the node's dispositor is strong, where it sits in an upachaya house, and for a specific purpose named by a qualified astrologer.
