The ancient law in the Orient was similar to the law of Hamurabi, "an eye for an eye, a tooth for a tooth," and was rigorously enforced even if death was caused accidentally. In this type of environment, and since the present system of free sparring had not yet been developed, it was impossible for a student of the martial arts to practise or test his individual skill of attack and defense against actual moving opponents.

Individual advancement was certainly hindered until an imaginative practitioner created the first patterns. Patterns are various fundamental movements, most of which represent either attack or defense techniques, set to a fixed and logical sequence. The student systematically deals with several imaginary opponents under various assumptions, using every available attacking and blocking tool from different directions. Thus pattern practice enables the student to go through many fundamental movements in series, to develop sparring techniques, improve flexibility of movements, master body shifting, build muscles and breath control, develop fluid and smooth motions, and gain rythmical movements.

It also enables a student to acquire certain special techniques which cannot be obtained from either fundamental exercises or sparring. In short, a pattern can be compared to unit tactics or a word, if fundamental movement is an individual soldier's training or alphabet. Accordingly, pattern, the ledger of every movement, is a series of sparring, power tests, feats and characteristic beauty.

Though sparring may merely indicate that an opponent is more or less advanced, patterns are a more critical barometer in evaluating an individual's technique. The following points should be considered while performing patterns: 1 Pattern should begin and end at exactly the same spot. This will indicate the performer's accuracy. 2. Correct posture and facing must be maintained at all times. 3. Muscles of the body should be either tensed or relaxed at the proper critical moments in the exercise. 4. The exercise should be performed in a rhythmic movement with an absence of stiffness. 5. Movement should be accelerated or decelerated according to the instructions in this book. 6. Each pattern should be perfected before moving to the next. 7. Students should know the purpose of each movement 8. Students should perform each movement with realism. 9. Attack and defense techniques should be equally distributed among right and left hands and feet.

There are a total of twenty four patterns in Taekwon Do. 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 travellers who pass by the eternal years of an aeon in a day It is evident that no one can live more than a limited amount of lime. 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.
