The Spirits of Nature is a book about angels, fairies, elves, gnomes and other "nature spirits". It's fascinating reading, and based on extensive research into the ancient traditions of Egypt, India, the pre-Colombian Mayas and Incas, and others. The book explains where different types of nature spirits live, their behavior, and their relationships with humans. There is a chapter on where and under what conditions they can be seen. These "invisible" creatures are not "supernatural" but simply live on their own plane of existence, even though modern man has all but lost the ability to perceive them. There is also a detailed explanation of the 7 planes, from the physical through the psychic to the spiritual realms.
The Spirits of Nature explains things about plants and animals that many people perceive intuitively, with a pet for example. It is a real gem for those interested in learning more about life and the world around us.
