YANTRA is a geometric design, in this case etched on copper, and infused with healing PRANA (life energy). The gold plated version as a layer of gold on top of the copper. These particular Yantras are 1.25 inch diameter medallions, with ring attached for wearing around the neck, always with the design facing you. Many people wear these Yantras to reduce tension on the mind, heal bodily pains, induce a better nights rest & increase clarity of thought, etc. Our Yantras have been charged at SHIVADHAM, a temple in India where great energies for the planet are manifest and can be felt.
