THE NATURE OF LIFE is a new interpretation of the traditional teachings of Tibetan Medicine for today's lifestyles. Tibetan Medicine rests on the 3-Humoural Theory - Earth, Fire and Air - which governs each of us. Here the subject has been updated and expanded in a way which makes it more accessible and in order to discover to which Nature (or Humour) the reader belongs, there is a Quiz. The basis of Tibetan Medicine is the 3-way approach of Diet, Lifestyle and Behaviour. Such advice was traditionally given along with the physical medicine of powders and pills. Along with these, new chapters covering such subjects as Personality, Appearance, General Health, Best/Worst Environment, Treatments and Therapies, plus Interiors/Room Scenting for each Nature have been developed based on the Author's extensive study and research of the subject. There is a list of European medicinal herbs, which best approximate those used in Tibetan Medicine and are widely available. Appendices 1-4 detail traditional Tibetan Medicines and Practices and 'Where to find more information on Tibetan Medicine' lists websites around the world where interested persons can find a Tibetan practitioner, or order Tibetan herbal medicines.
