Taekwondo is not just a physical martial art but also a discipline that encompasses a philosophical foundation. One unique aspect of Taekwondo philosophy is its emphasis on the five tenets known as the “Five Codes of Taekwondo” or “Taekwondo Oath,” which are:

1. Courtesy (Ye-ui): This tenet emphasizes showing respect and consideration for others. It teaches practitioners to be polite, humble, and to treat others with kindness and dignity.

2. Integrity (Yom-chi): Integrity in Taekwondo means being honest, sincere, and having strong moral principles. It encourages practitioners to be truthful, upright, and to uphold ethical standards in all aspects of life.

3. Perseverance (In-nae): Perseverance is the quality of persisting in the face of challenges and difficulties. In Taekwondo, practitioners are taught to cultivate mental strength, determination, and resilience to overcome obstacles and achieve their goals.

4. Self-Control (Guk-gi): Self-control involves mastering one’s impulses, emotions, and behaviors. It teaches practitioners to maintain discipline, restrain from aggression, and to act with calmness and composure even in stressful situations.

5. Indomitable Spirit (Baekjul-boolgool): Indomitable spirit is the unwavering resolve to confront and overcome adversity. It encourages practitioners to never give up, to face challenges with courage and determination, and to strive for self-improvement continuously.

These five tenets not only guide the physical training in Taekwondo but also serve as principles for personal development and moral conduct. They promote a holistic approach to martial arts training, emphasizing the importance of character development, self-discipline, and ethical behavior both inside and outside the dojang (training hall).
