Taegeuk is a symbol representing the principles of the cosmos creation and the norms of human life. The circumference of the Taegeuk mark symbolizes infinity and the two parts, red and blue, inside the circle symbolize yin(negative) and yang(positive), which look like rotating all the time. Therefore, Taegeuk is the light which is the unified core of the cosmos and human life and its boundlessness signifies energy and the source of life. The yin and yang represents the development of the cosmos and human life and the oneness of symmetrical halves, such as negative and positive, hardness and softness, and materials and anti-materials.
The eight bar-signs (called kwae) outside the circle are so arranged to go along with the Taegeuk in an orderly system. One bar means the yang and two bars the yin, both representing the creation of harmonization with the basic principles of all cosmos phenomena. The Taegeuk, infinity and yin-yang are the three elements constituting the philosophical trinity as mentioned in the Samil Sinko, the Scripture of Korean race.

According to the old book of history, Sinsi Bonki, around(B.C.35), a son of the 5th emperor of the Hwan-ung Dynasty in on ancient nation of the Tongyi race whose name was Pokhui, was said to have received the Heaven's ordinance to have an insight in the universal truths, thereby observing rituals for the Heaven and finally receiving the eight kwaes (bar signs). After all, this has been passed down through a long, long history by King Mun, Chou tsu, Confucius and Scholar Kim Il bu, all descendants of the Tongyi race. Scholar Kim finally completed the present Taegeuk mark.
The Taegeuk poomsae was established on the basis of profound philosophy of Taegeuk to be trained by the Taekwondo beginners. Its poomsae line and seogi are based on the invariable basic though of Taekwondo. The monism of Taegeuk is the frame of this poomsae, each Kwae being reflected in a pattern of Taegeuk poomsae, which elucidates the Taekwondo spirit and the profoundness of Taekwondo techniques.
The Taekwondo poomsaes are so designed to cope collectively with the outside threats in that society has already developed into an organized group, weakening the necessity of solitary individual defense measures. For the constituents of community, the practice and transmission of techniques should be convenient and less complicated. In that sense, the poomsae has been gradually systematized through practical experiences togther with the help of philosophical and medical sciences.
It is believed that in ancient times the poomsae was practiced among the ruling class and the first poomsae pattern appearing in the documents or monuments was around the first century, when Koguryo reined the Han (Korean) race.
Each poom of the poomsae has been inherited through a long history of about 5,000 years, finally as a product of scientific technique formulated on the basis of the traditional national spirit and practical experiments. From the technical viewpoint, the poomsae itself is Taekwondo, and the basic movements are no more than the preliminary actions to reach the poomsae. The Kyorugi is a practical application of the poomsae and the Taekwondo spirit is manifested not in an abstract mental philosophy expressed in the documents but in the actions of poomsae. Then, what is the Taekwondo poomsae? The poomsae is the style of conduct which expresses directly or indirectly mental and physical refinements as well as the principles of offense and defense resulting from cultivation of Taekwondo spirit and techniques.
The poomsae is a series of movements for offense and defense techniques which can be practiced and trained, even without presence of an instructor, in accordance with the fixed patterns. Therefore, the poomsae has the merits, by its practice, to make the trainee enhance the Kyorugi techniques and applied techniques including special techniques which can hardly be practiced by the training of each separate basic movement alone.
The poomsae can be trained along the imaginary or drawn poomsae line, which marks the position of foot and the line direction to move along.
The poomsae is a series of alternate attack and defense actions : therefore, there are frequent changes of actions and connections of techniques. One must pay attention to the movement of body, eyes, respiration, etc. The steps of paying attention are as follow :
A completion of poomsae can be achieved through hard training following the 5 steps :
The poomsae are categorized by the technique, composition and points of stress, which are classified each into 3 minor breakdowns.
This contains more techniques of chagi and makki than are needed for practical use. Practicable techniques must be selected among them in the course of training.
This includes practically used techniques only, which are classified into a series of chigi techniques, a series of makki techniques and a balanced combination of chigi and makki techniques.
This is classified into the basic course and the advanced course, in the advanced course, the training of cultivating the inner strength of body by means of controlling the respiration is included. The variations of techniques should be mastered through hard training.
Taegeuk poomsaes from 1(il) jang to 8(pal) jang are classified as Kup grader's poomsaes and the poomsaes from Koryo up to Ilyo as Dan-grader's, i.e., black-belter's poomsaes. The poomsaes consists of basic movements and poom and they are so arranged to fit the frame of movement direction, which is called the poomsae line. The poomsae lines are described after symbols or Chinese characters.
