An authoritative, in-depth guide to crystals written by one of the world's leading experts. Taking an informed, realistic look at crystals, at their properties and how best to use them, this looks set to become a bible for crystal users. The past two decades have seen a phenomenal rise in the use of crystals as instruments of healing and personal enlightenment. Yet many have been disappointed with the results. This book argues that what we need is a fundamental shift, not just in the ways we see crystals, but in our whole relationship to the world around us. The book includes a fascinating exploration of how crystals come into being, and looks at how their make-up makes them so perfect for energy work. It explores new ways they can be used for personal development, and how to work with them to tap into the powerful dimension of colour.
