Their techniques, although simple, have proven effective through the innumerable healers who have handed down these teachings across the generations. With the permission of his elders and teachers, Luke Blue Eagle shares the therapeutic and spiritual use of crystals as taught in the traditions of First Nations tribes. He offers guidance and teachings designed to spiritually and energetically prepare you for crystal healing work, detailing the connections between the five elements and crystals as well as the energetic properties of different colors as they manifest in stones. He explains how to purify, care for, and protect your crystals, including how to establish right relationship with a crystal and perform a consecration ceremony for a new gemstone.
