This is one of the reasons that Taekwondo is called an art of self-defence. It also implies a way of thinking and life, particularly in instilling a concept and spirit of striet self-imposed discipline and an ideal of noble moral rearmament. The nearest description of it is almost a cult. Translated literally "Tae" stands for jumping or flying, to kick or smash with the foot. "Kwon" denotes the fist chiefly to punch or destroy with the hand or fist. "Do" means an art or way the right way built and paved by the saints and sages in the past. Thus taken collectively "Taekwondo" indicates the mental training and the techniques of unarmed combat for self-defence as well as health, involving the skilled application of punches, kicks, blocks and dodges with bare hands and feet to the rapid destruction of the moving opponent or opponents.
Taekwondo definitely enables the weak to possess a fine weapon together with a confidence to defend him or herself and defeat the opponent as well. Of course, wrongly applied, Taekwondo can be a lethal weapon. Therefore mental training must always be stressed to prevent the student from misusing it. The feats of Taekwondo are great in number. To mention a few is probably pertinent. For instance, flying over a mounted motorcycle or eleven persons in line to attack a target with the foot: breaking an inch thick pine board placed at a height of ten or eleven feet with the foot: breaking two pieces of red brick with a open hand or knife-hand; smashing seven or eight pieces of two inch thick pine board at a single blow with the fist: attacking two targets with same foot in succession while flying and so on. To the layman in the street, such feats may sound impossible, but to the serious students of Taekwondo and the exponents of this art, it is quite ordinary. Of course, by mastering this art it does not mean that you will be asked to do acts of impossibility.
  Particularly if someone should challenge you to kill a wold bull with your bare hands. Therefore it is clear that equivalent demonstrations of such effective use of pure somatic force is not to be seen in other forms of physical combat technique.
  Incessant training is essential to keep oneself in top form and physical condition. In training, all the muscles of the human body will be used.
  From the use of one's muscles, it will be possible to harness all available power generated by every muscular contraction. It will then be necessary to deliversuch power to the human target especially to where the most vulnerable points or vital spots of one's opponent are located, in particular when the opponent is in motion. At this point, it is necessary to remind the students of Taekwondo that this art of self-defence is specially designed for swift retaliation against the moving aggressor.
