To
explain the heart governor and triple heater in western medical terms is very
complicated; they can best be understood if we say that the heart governor
supervises the entire process of circulation, thus connecting together the
entire organism. It is approximately
equivalent to the autonomic nervous system.
The triple heater is traditionally said to control the three systems
(respiratory, digestive, excretory) which regulate body temperature. It its function as regulator of body
temperature, it is closely related to the skin.
These two organs are the most fundamental to life; even the most
primitive life forms have an autonomic nervous system and skin.
In
the far east, yin is the name given to that force which produces
expansion. Water, air, trees, flowers,
etc are all expanding elements in nature, since their essential tendency is to
forever fill up the dimensions of space.
Therefore, we consider as yin anything that grows to a relatively great
size in a relatively short time.
It takes
a great binding force (yang) to balance the great expansion created by yin
(drugs, alcohol, sugar, etc). It is due
to this difficulty in maintaining equilibrium that all kinds of sicknesses
arise.
Energy is
yang. Inertia is yin. Activity is yang and passivity is yin.
