This little book is intended to give an overview of how the energy systems of the Human body work. It provides basic information and is pitched for people who work in non-precise ways with energy and those who are studying these topics. It is not intended to provide information in the very detailed form that Acupuncturists need.All energy therapies (e.g. Reiki, Reflexology, EFT, and TFT) work with the energetic parts of ourselves. They have been in use in various forms for centuries. In some cultures they are widely used and accepted, in others they have fallen into disuse and disrepute as the scientific model of life became established. This is particularly true of modern Western Cultures.
