The Mars vrat is kept on Tuesday — traditionally one meal after sunset, without salt. It is the household remedy for a weak Mars, and unlike a gemstone it cannot be kept against your chart.
The weekday fast is the household remedy — kept on the graha’s own day, usually one meal after sunset and no salt. It is as much a discipline as a ritual: the point is the weekly act of restraint, held long enough to mean something.
The Tuesday fast is kept with jaggery and roasted gram, one meal, no salt — and is usually paired with Hanuman worship.
An ill-placed Mars shows as anger, accident-proneness, conflict with siblings, and impatience that costs more than it wins. The remedies aim to give that energy a channel rather than suppress it.
Tuesday. Fasting, charity and mantra japa for Mars all belong to that day.
The mantra, the weekday fast and the charity are safe for anyone — they address Mars without amplifying it. Red Coral is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
