This was the first book I ever read on visualisation. For me, this and the audio book, are the best grounding available in honing visualisation skills. The book contains an explanation of the techniques and exercises to help learn them. Shakti makes it all very easy to understand. It did help having a copy of the exercises in audio form, so that I could follow them easily.Perhaps this book changed my life the most out of any other book. After completing some of the exercises in this book, I emigrated to a new country and started a new life. I have to admit, however, I did not take on board many of the spiritual lessons in the book, as I focussed mostly on the meditative/visualisation techniques presented therein.
