Flag of KOREA (Tae Kuk Ki)
The Korean flag symbolizes much of the thought, philosophy and mysticism of the Orient. The symbol, and sometimes the flag itself, is called the "Tae Geug".
The
central element (sometimes called the "yin, yang symbol") consists of
a circle divided equally into two halves. The upper (red) represents
the Yang and the lower (blue) represents the Um, an ancient symbol of
the universe. The two opposites express the dualism of the cosmos: fire
and water, day and night, masculine and feminine and so on. While there
is a constant movement within the sphere of infinity, there is also BALANCE and HARMONY.
