Agate Export offers a huge collection of Zodiac symbol black agate engraved coaster. Among the methods for spiritual development are practices that focus on the activation of ?energy centers? in an ascending sequence from the hips to the crown of the head. The principal hazard in exploration of the chakras is the sequential order of the activation. The theory is that the root chakra, located at the base of the spine, is the conduit for spiritual energy (prana) that arises and activates subsequent energy centers. Place an order at Agate Export.
