কেতু remedies are kept on মংগলবার: chant স্রাং স্রীং স্রৌং সঃ কেতবে নমঃ, donate রংগ-বিরংগা বস্ত্র, কালে তিল, and keep the weekday fast. লহসুনিযা is the graha's stone, but it should only be worn once কেতু 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 কেতু without amplifying it. লহসুনিযা is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
মংগলবার. Fasting, charity and mantra japa for কেতু 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 লহসুনিযা 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.
