In ancient times, poomse was the only method of initiating the secret of the martial art from Master to student. There are three types of formal exercises fundamental to the study of taekwondo; basic or base forms, law or command forms and taeguk (bigness, eternity) forms. Each set of forms was conceived with a particular philosophical viewpoint: a reference to the ancient Oriental concept of yin and yang - two opposing forces interacting, forever changing yet always constant. They contain the essence of everything. Thus, taeguk has no form, no beginning and no ending either. Nevertheless, everything comes from taeguk. When performing poomse, the student should bear in mind that we are all born as we shall die, naked, bringing nothing into this world and taking nothing out of it.
Taeguk poomse are patterns of modern fighting sequences stemming from eight major branches of philosophical theories, each of which is represented by respective characters known as trigrams. There are eight basic poomse for Kup grades to learn. Each poomse is a training pattern upon which a competence and understanding of taekwondo is built, demonstrated and nurtured. They all embody all the principles of natural phenomena. Accordingly, taeguk poomse are represented by a trigram. As you move along the movement lines bear in mind their main principle theory.
