In this in-depth yet easy-to-follow guide, crystal healing teacher, Nicholas Pearson, offers a full-colour compendium of 200 crystals and gemstones as well as a hands-on practical handbook on crystal healing, perfect for those just beginning their crystal journey as well as long-time stone lovers seeking an all-in-one reference. The handbook of crystal use opens with a thorough explanation of crystal energy, including its interactions with the human energy field and teaches readers how to extrapolate what a crystal does based on its composition, crystal structure, formation process and other properties. In the chapters on techniques, Pearson offers guidance on selecting your crystals and gemstones, then step-by-step instructions on how to cleanse, charge, activate and programme them. He explains how to make crystal grids and healing layouts, including templates for both and, also, discusses the numerology and geometry of crystal grids. He explores the essentials of crystal elixirs, complete with elixir recipes and details how to perform crystal meditations, clear the energy centres and the aura and practise more advanced techniques, such as engaging with the crystal devas, creating sacred space and practices for spiritual hygiene and protection. The compendium includes 200 rocks, minerals, gemstones and crystal formations, organised alphabetically and featuring full-colour photographs. Each entry includes geological information and the physical, psychological and spiritual healing qualities for every stone. Some stones, such as jasper and quartz, have multiple varieties, each given their own entries to provide a thorough reference guide for crystal healers and collectors. This accessible yet comprehensive guide offers the essentials of crystal energy healing paired with a highly illustrated stone directory to give you everything you need to know about crystal basics in one handy volume.
