ಚಂದ್ರ daan is given on ಸೋಮವಾರ: ದೂಧ, ಚಾವಲ, ಸಫೇದ ವಸ್ತ್ರ, ಚಾಂದೀ. 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.
Moon charity goes to mothers and to women’s shelters: rice, milk, white cloth and silver, given on Monday.
An afflicted Moon reads as overreaction, low mood, thin sleep and a general sense of being unsettled. Monday observance, Shiva worship and time near still water are the standard responses.
ಸೋಮವಾರ. Fasting, charity and mantra japa for ಚಂದ್ರ all belong to that day.
The mantra, the weekday fast and the charity are safe for anyone — they address ಚಂದ್ರ without amplifying it. ಮೋತೀ is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
