Heiner Fruehauf has researched the ancient symbolism that defines the finer points of Chinese organ network function for 10 years. His prolific research project will eventually culminate in the creation of an illustrated compendium on the macrocosmic and microcosmic ramifications of organ network theory. Since the publication of this effort is still years away, he has decided to make a selection from his cache of existing research papers available now by publishing them on The first installment of these papers consists of a detailed etymological analysis of the character of fei 肺 (lung), and the defining statement on the lung’s function/office in chapter 8 of the Huangdi neijing suwen.
