The Reason for 24 Patterns
The life of a human being, perhaps 100 years, can be considered as a day when compared with eternity. Therefore, we mortals are no more than simple travelers who pass by the eternal years of an eon in a day. It is evident that no one can live more than a limited amount of time. Nevertheless, most people foolishly enslave themselves to materialism as if they could live for thousands of years. And some people strive to bequeath a good spiritual legacy for coming generations, in this way, gaining immortality. Obviously, the spirit is perpetual while material is not; therefore, what we can do to leave behind something for the welfare of mankind is, perhaps, the most important thing in our lives.

Here I leave Taekwon-Do for mankind as a trace of man of the late 20th century. The 24 patterns represent 24 hours, one day, or all my life. The name of the pattern, the number of movements, and the diagrammatic symbol of each pattern symbolizes either heroic figures in Korean history or instances relating to historical events.
