Book One: Filling the Void The lack of warmth is the fundamental evil of our time, reflected in interpersonal relationships as well as in modern medicine, where, for example, catabolic, cytostatic, or antibiotic therapies promote a basic inhibition of warmth in the body. Additionally, air conditioning, chilled foods and drinks, and spending more and more time indoors have made our lives colder over the past 50 years. However, life is warmth, whether through sunlight, warm food, or human warmth. Consequently, more and more illnesses arise from cold that cannot be treated with conventional therapy. Traditional Chinese Medicine, particularly the Fire School (Huo Shen Pai), offers the only proven solution to this problem over centuries, which is to save the life fire in the Kidney Yang.
