Korean flag symbolizes much of the thought and philosophy
of the Orient. The symbol, and sometimes the flag itself,
is called T'ae Kuk.
Depicted on the flag is a circle divided
equally and locked in perfect balance. The red section represents
the Yang (plus) and the blue section the Um (minus), an ancient
symbol of the universe which originated in China. These two
opposites express the dualism of the cosmos: fire and water,
day and night, dark and light, construction and destruction,
masculine and feminine, active and passive, heat and cold,
plus and minus, and so on.
The central thought in the T'ae Kuk
indicates that while there is a constant movement within
the sphere of infinity, there are also balance and harmony.
Three bars at each corner also carry
the ideas of opposition and balance. The three unbroken bars
stand for heaven; the opposite three broken bars represent
the earth; the two bars with a broken bar in-between symbolize
fire; the opposite is the symbol of water.
