The South Korean Flag 태극기
has four bold, black markings on each corner surrounding the red and blue, circular symbol in the middle.
I find the explanation of the red and blue, circular symbol to be simple enough for my mind to grasp. It's yin-yang, the equality/balance of good and evil.
So my question surrounds the bold, black markings in the corners.
This table, in of itself, is easy to read. Where I get lost is that there are so many meanings.
Is it as easy as each trigram (괘/卦) means each of those things, or is there a better, more full explanation on how to interpret the great number of meanings that are represented?
