This book is wonderfully written with easy to use instructions and allows the reader to use or customize what they read into their every day life. I am recommending this to my clients and friends whether you have done a crystal course or not. Even with the Margaret's spiritual belief coming through it is easy access to anyone with any beliefs. I also like how Margaret has added anecdotes of her experience in the instructions. I am differently buy a copy when this is released for my collection in fact this is the book I have been trying to find for years.
