BASICS OF “YIN” and “YANG” SEE • http://en.wikipedia.org/wiki/Yin_and_yang
The nature of yin–yang • Yin is characterized as slow, soft, yielding, diffuse, cold, wet, and receptive; and is associated with water, earth, the moon, female and nighttime. • Yang is fast, hard, solid, focused, hot, dry, and aggressive; and is associated with fire, sky, the sun, male and daytime.
The nature of yin–yang • an initial quiescence or emptiness sometimes symbolized by an empty circle • dropping a stone in a calm pool of water will simultaneously raise waves and lower troughs between them, and this alternation of high and low points in the water will radiate outward until the movement dissipates and the pool is calm once more.
The nature of yin–yang • Yin and yang thus are always opposite and equal qualities. Further, whenever one quality reaches its peak, it will naturally begin to transform into the opposite quality: for example, grain that reaches its full height in summer (fully yang) will produce seeds and die back in winter (fully yin) in an endless cycle.
The nature of yin–yang • It is impossible to talk about yin or yang without referring to the opposite • yin and yang are bound together as parts of a mutual whole (i.e. you cannot have the back of a hand without the front)
The nature of yin–yang • Imagine a race with only men or only women; this race would disappear in a single generation. • Men and women together allow the race they mutually create (and mutually come from) to survive.
A seed will sprout from the earth and grow upwards towards the sky – an intrinsically yang movement. Then, when it reaches its full potential height, It falls to the ground
"Yang" and "Yin" in place names • Many places in China, such as Luoyang, contain the word "Yang", and such as Huayin, the word "yin". • a very old way to assign place names.
"Yang" and "Yin" in place names • "Yang" means that a place is on the south slope of a mountain or on the north bank of a river – for example, Luoyang is on the north bank of the Luo River. • "Yin" means that a place is on the north slope of a mountain or on the south bank of a river – for example, Huayin is on the north slope of Mount Hua.
"Yang" and "Yin" in place names • The interaction of the two gives birth to things.Yin and yang transform each other: like an undertow in the ocean, every advance is complemented by a retreat, and every rise transforms into a fall. (Iconic) • Newton: “For every action there is an equal and opposite reaction.” (Mathematika)
