The silver medallion is called a “kavach”, or protective shield.
Based on classical/ancient numbers, the KAVACH strengthens all of the benefic planets in a chart, and reduces the impact of the afflictions caused by the malefic planets.
The remedy is both for the birth chart, and for the daily transit chart.
Kavach orders are placed with my professor in India on the 1st and 15th of every month. Your order will be included in the next shipment of kavaches either on the 1st or 15th (whatever date is closer to when you placed your order).
Package is sent via flat rate of $20 for US – USPS Priority Insured (included in price of the kavach). Can also be sent to other countries outside the US.
