At the heart of this kit are 10 beautiful crystals which have been specially selected to provide a full range of healing benefits, from improving sleep to enhancing creativity and boosting energy levels. An accompanying book, "The Essential Crystal Handbook", explains all the ways in which you can use crystals, including chakra healing, gem essences and crystal layouts which involves placing stones on the body to focus their energies. The book gives profiles of more than 100 crystals, each one illustrated with a superb, specially commissioned photograph. Also included in the kit are two wall charts for ready reference: a crystal healing body map, which shows the most appropriate crystals to use to heal disorders in each part of the body; and a crystal identifier showing vibrant colour photographs of a wide range of crystals, each labelled with its name to allow at-a-glance identification.
