Crystals by Chakra

Chakras are the energy centers that keep the spiritual body in balance. Each chakra is associated with specific qualities and aspects of our being.
From the Root chakra, grounding us to the earth, to the Crown chakra, connecting us to higher states of consciousness, the chakra system provides a roadmap for understanding and harmonizing our inner energies. Activating these chakras is like tuning into different frequencies of one's own existence.
