In Hinduism and various Indian religions, "kavach" (meaning "shield" or "armor" in Sanskrit) represents a form of spiritual or ritualistic protection designed to safeguard an individual from harm, negative influences, or adverse effects. This protection often involves the use of amulets, charms, or specific rituals that are believed to create a shield around the person, helping them to mitigate and neutralize negative energies, especially those linked to the malefic effects of planets as interpreted in Vedic astrology. The practice of using kavach to address planetary influences is grounded in the belief that celestial bodies impact various aspects of human life. By wearing specific gemstones, Rudraksha beads, or performing dedicated rituals, individuals seek to counteract the adverse effects and harness positive energies associated with these celestial forces. Below is an expanded explanation of the kavach for each planet, detailing the recommended gemstones, Rudraksha beads, the affected bodily organs, days of invocation, and appropriate mantras.
