Chakra: Root and Sacral
Copper is a conductor of energy, and amplifies thoughts when sending and receiving psychic communication. Balances the body's polarities. Combats fatigue, lethargy, restlessness, and non-acceptance of one's self.
The Tetrahedron (aka PYRAMID) represents the element of Fire and is linked to the Solar Plexus; the center for personal power and acceptance. It creates the natural balance between the physical and spiritual. Each side sits flat, no matter how it is turned, making it the perfect symbol for balance and stability.
