Principles are the moral values on which Taekwon-do is based.

Everyone must observe the rules to go further in the practice of Taekwon-do but also to form his character.

The principles of Taekwon-do (Taekwon-do Jungshin)

  • Courtesy – Ye Ui
  • Integrity – Yom Chi
  • Perseverance – In Nae
  • Self-control – Guk Gi
  • Invincible Spirit – Baekjul Boolgool

  • Encourage the idea of mutual concessions
  • Shame for his own sins, contempt for those of others
  • Politesseen towards others
  • Greet the feeling of justice and humanity
  • Distinction between instructor and student, older and younger
  • Behavior according to the label

Integriteit (Yom Chi)
In Taekwon-do, integrity means the judgment of good and evil, of conscience and guilt in the case of wrongdoing.

The pupil who puts himself in the spotlight by “manufacturing” broken equipment for demonstrations.
An instructor who camouflages his technique and launches false flattery to his students.
Request a diploma from an instructor or try to buy it.
Obtain a degree for the purpose of ego or sense of power.
An instructor who teaches and applauds his art for materialistic purposes.
Shame to seek advice from subordinates, young or lower grade persons

Perseverance (In Nae)

An old oriental proverb says: “Patience leads to virtue and merit.”, “You can build a peaceful home by being 100 times patient.” Certainly luck and advancement are the merits of a patient person. To achieve something, be it a higher degree or the perfection of a technique, it will be necessary to set goals and constantly pursue them. Robert Bruce learned his lesson of perseverance and determination from the stubborn efforts of a small spider; it was perseverance and determination that eventually led to the liberation of Scotland in the 14th century One of the most important secrets to becoming a great and respected Taekwon-doka is to overcome all difficulties by perseverance. Confucius said: “Someone who is impatient in insignificant matters will rarely succeed in matters of great importance.”

Self-control (Guk Gi)

Self-control is of utmost importance, both inside and outside the dojang, both in free fighting and in personal affairs. A loss of control in free combat can lead to bad consequences for both taekwon-dokas. The inability to live and work in men’s abilities or environment is also due to a lack of self-control. Lao-Tzu said, “The strongest is the one who wins by himself and not by another.”

Invincible Spirit (Baekjool Boolgool)

“Here rest 300 people, who did their duty,” a simple saying for one of the greatest examples of courage for the good of humanity. Although they met the crushing armies of Xerxes, Leonidas and his 300 Spartans showed humanity what an invincible soul was during the Battle of Thermopylae. A serious taekwon-doka will be honest and modest at all times. When confronted with injustice, he will act without fear or doubt, with an invincible soul, no matter against whom and how many opponents. Confucius said: “It is an act of cowardice when one does not rise up against injustice”. History has taught us that those who honestly and resolutely pursued their goals with the feeling of invincibility never failed to reach them.
