Query: .a spiritual approach to singing, speaking and communicating

" The Voice, a Spiritual Approach to Singing, Speaking and Communicating" What can be said about this book, except that it is a work of genius. I have read books on singing, by many prestigious teachers and singers, none of which come close to this one! This book is unique in its field , simply because the author is unusually gifted. Not only is she intimately aquatinted with the voice, and an incredible communicator ,she is also able to view and treat the voice from a spiritual perspective. The culmination of these talents in this book , makes it a three dimensional work of art . For any one who aspires to sing , in any capacity, this book is almost as essential as your voice.
