The Book of Crystal Healing
While its focus is on the therapeutic uses of crystals,The Book of Crystal  Healingprovides much more than a prescription for salubrity. Liz Simpson considers  the history of crystals, their value as gems and tools, and their role in technological  advances.The Book of Crystal Healingis grounded in current scientific theories  regarding vibrational states and energy fields rather than venturing into some of the  wilder explanations of crystal workings. With intuitive instruction, Simpson helps you  assemble your own crystal collection, offers advice on which shapes and materials are  best suited for different purposes, and shows how to use crystals in healing meditation.
