మంగల daan is given on మంగలవార: మసూర దాల, లాల వస్త్ర, గుడ఼, తాంబే కే బర్తన. Charity addresses a graha without amplifying it, which is why it is prescribed where a gemstone is withheld.
Daan is charity aimed at a specific graha, given on its day and matched to its significations. Classically it is the remedy that works when a gemstone would be dangerous — it addresses the planet without amplifying it, which is why it is prescribed for Rahu and Saturn where stones are withheld.
Mars charity is red lentils, red cloth and copper, given on Tuesday; classically it goes to brothers in need and to soldiers’ welfare.
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.
మంగలవార. Fasting, charity and mantra japa for మంగల all belong to that day.
The mantra, the weekday fast and the charity are safe for anyone — they address మంగల without amplifying it. మూంగా is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
