The ಬೃಹಸ್ಪತಿ beeja mantra is " ಗ್ರಾಂ ಗ್ರೀಂ ಗ್ರೌಂ ಸಃ ಗುರವೇ ನಮಃ". The classical count is 19,000 repetitions, built up over weeks from one mala of 108 a day, and ಗುರುವಾರ 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 Guru mantra is chanted on Thursday; for many, worship of one’s own teacher on that day is the more direct Jupiter remedy.
An afflicted Jupiter reads as poor judgement, lost opportunities, difficulty with teachers or children, and a loss of faith in one’s own direction. Thursday observance and service to teachers are the classical answer.
The classical Sankhya is 19,000 repetitions, completed over weeks rather than at once. Begin with one mala — 108 — a day and build up; sincerity matters more than arithmetic.
ಗುರುವಾರ. Fasting, charity and mantra japa for ಬೃಹಸ್ಪತಿ all belong to that day.
The mantra, the weekday fast and the charity are safe for anyone — they address ಬೃಹಸ್ಪತಿ without amplifying it. ಪುಖರಾಜ is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
