Venus remedies are kept on Friday: chant Om Dram Dreem Draum Sah Shukraya Namah, donate rice, sugar, and keep the weekday fast. Diamond is the graha's stone, but it should only be worn once Venus has been established as a functional benefic for your lagna.
Shukra remedies are for marriage, comfort and the capacity to enjoy — Venus governs partnership and refinement. Friday practice and Lakshmi worship are the traditional core, and the sixteen-Friday vow is the best known of them.
A weak Venus shows as difficulty in marriage, restless dissatisfaction, and money that goes on pleasure. The remedies steady the relationship rather than the bank balance.
The mantra, the weekday fast and the charity are safe for anyone — they address Venus without amplifying it. Diamond is not: a planetary gem strengthens whatever the graha is already doing, so it needs a chart reading first.
Friday. Fasting, charity and mantra japa for Venus all belong to that day.
The classical Sankhya is 16,000 repetitions, completed over weeks rather than at once. Begin with one mala — 108 — a day and build up; sincerity matters more than arithmetic.
Diamond should be avoided by Aries, Scorpio, Sagittarius, Pisces lagna, where the graha is a functional malefic and the stone amplifies exactly what you were trying to correct. Every lagna not listed as recommended needs the chart read first.
