The চংদ্র beeja mantra is " শ্রাং শ্রীং শ্রৌং সঃ চন্দ্রমসে নমঃ". The classical count is 11,000 repetitions, built up over weeks from one mala of 108 a day, and সোমবার is its day.
Mantra is the safest of the classical remedies: it can be started today, costs nothing, and cannot be worn against the chart the way a stone can. The Sankhya — the prescribed number of repetitions — is completed over weeks, beginning with one mala of 108 a day and building up. Sincerity matters more than arithmetic.
The Chandra mantra is chanted on Monday nights and on Purnima; the Mahamrityunjaya mantra is used for the same afflictions through Shiva.
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 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.
সোমবার. Fasting, charity and mantra japa for চংদ্র all belong to that day.
The mantra, the weekday fast and the charity are safe for anyone — they address চংদ্র without amplifying it. মোতী is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
