Spirit Guides and Angel Guardians by Richard Webster
They come to our aid when we least expect it, and they disappear as soon as their work is done. Invisible helpers are available to all of us. In fact, we all regularly receive messages from our guardian angels and spirit guides, but usually fail to recognize them. This book will help you to realize when this occurs. And when you carry out the exercises provided, you will be able to communicate freely with both your guardian angels and spirit guides.
