Moon remedies are kept on Monday: chant Om Shram Shreem Shraum Sah Chandramase Namah, donate milk, rice, and keep the weekday fast. Pearl is the graha's stone, but it should only be worn once Moon has been established as a functional benefic for your lagna.
Chandra remedies steady the mind. The Moon governs emotion, the mother, sleep and the sense of being at home in oneself, and its remedies are the gentlest in the classical set — the Moon has no traditional enemies, so almost nothing here can backfire.
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.
The mantra, the weekday fast and the charity are safe for anyone — they address Moon without amplifying it. Pearl is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
Monday. Fasting, charity and mantra japa for Moon all belong to that day.
The classical Sankhya is 11,000 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 Pearl 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.
