The twin concepts of Yin and Yang are attributed to ancient Chinese cosmology
and are representative of the dualism, or two-sidedness, that exists
within the universe.
The principle
of polarity is to be found everywhere in the universe: heaven and earth; the
finite (the earth) and the infinite (the atmosphere and everything above the
earth); the visible (the earth) and the invisible (heaven and air); above (the
sun and warmth) and below (the earth and cold), and so on. Polarity allows
movement and therefore change; for example, the earth moves and rhythmically
changes its position in relation to the sun. This brings about the slow change
from day and daylight through the dusk into the darkness of night. The concept
of continual change, a fundamental idea in daoistic philosophy, is clearly
illustrated by the behaviour of water. It falls as rain on the earth. It
collects in rivulets, which become streams and then rivers which flow into the
sea. The water then evaporates, rising into the sky to fall as rain and
thereby completing the cycle.
Everything in
nature and all events in life have a relationship to each other which involves
opposing factors. These natural things and events are also in a continual
state of change as they are subject to the ebb and flow of cosmic forces. The
ideal state in nature and therefore in health is when these opposing forces
are in relative balance.
These
complementary opposites are neither forces nor material entities -nor are they
mythical concepts that transcend rationality. Rather, they are symbols used to
describe the continuous process of natural change. Yin and Yang are not only a
set of correspondences; they also represent a way of thinking where all things
are seen as parts of a whole. No entity can ever be isolated from its
relationship to other entities; no thing can exist in and of itself. There are
no absolutes, rather that everything is relative, flexible and changeable. Yin
and Yang must, necessarily, contain within themselves the possibility of
opposition and change. Each makes up for what the other lacks, and the
wholeness of the world would be incomplete if there were a deficiency of
either.
The original
meaning of Yin and Yang is representative of the mountains -both the dark
side and the bright side, or the contrasting shaded and sunny slopes of the
mountain. Yang means literally "the sunny side of the mountain" or
"illumination", while Yin can be translated as "the shadowy
slope", that is the state which exists after a period of illumination.
Yang can be defined as active, initiating, moving, spreading out, unfolding,
altering, dispersing, loosening, expanding, aggressive and as negation; ie. it
is that which changes what is already in existence. Yin is regarded as a force
which makes things concrete, materialises and somatises; as being completing,
confirming, corresponding, solidifying, thickening, organising, determining,
contracting, at rest, solid, compact and conservative.
Together the
Yin and Yang are depicted as a circle, one half dark and the other half light;
within the dark half there is a small light circle, and within the light, a
small dark one. This suggests that, though opposites, there is a necessary
relationship between the two; that is, Yin exists in Yang and Yang exists in
Yin. This changing combination of negative and positive, dark and light,
cold and hot which keeps the world spinning creates Ch'i or the life giving
force of the universe. The two sides of the symbol are not static; but,
rather, they stand as a rolling circle encompassing the other as it moves
through time, space, and dimension. The circle of the opposite element in the
center of this flow is called "The Seed of Change"; representing
that everything within the universe has the power to change it's own direction
during it's life span.
The Yin and
Yang represent all the opposite principles one finds in the universe. Each of
these opposites produce the other: Heaven creates the ideas of things under
Yang, the earth produces their material forms under Yin, and vice versa;
creation occurs under the principle of Yang, the completion of the created
thing occurs under Yin, and vice versa, and so on. This production of Yin from
Yang and Yang from Yin occurs cyclically and constantly, so that no one
principle continually dominates the other or determines the other. All
opposites that one experiences health and sickness, wealth and poverty,
power and submission can be explained in reference to the temporary
dominance of one principle over the other. Since no one principle dominates
eternally, that means that all conditions are subject to change into their
opposites.
This cyclical
nature of Yin and Yang, the opposing forces of change in the universe, mean
several things. First, that all phenomena change into their opposites in an
eternal cycle of reversal. Second, since the one principle produces the other,
all phenomena have within them the seeds of their opposite state, that is,
sickness has the seeds of health, health contains the seeds of sickness,
wealth contains the seeds of poverty, etc. Third, even though an opposite may
not be seen to be present, since one principle produces the other, no
phenomenon is completely devoid of its opposite state. One is never really
healthy since health contains the principle of its opposite, sickness. This is
called "presence in absence."
The Yin and Yang
accomplish changes in the universe through the five material agents, or
"wu hsing" -metal, wood, water, fire, earth- which both produce one
another and overcome one another. All change in the universe can be explained
by the workings of Yin and Yang and the progress of the five material agents
as they either produce one another or overcome one another: the movements of
the stars, the workings of the body, the nature of foods, the qualities of
music, the ethical qualities of humans, the progress of time, the operations
of government, and even the nature of historical change.
