Moral Culture (Jungshin Sooyang)

In Oriental philosophy, moral culture is the route to becoming the best person you can be – leaving a positive legacy for others.

At Sussex Taekwon-Do, we practice the five tenants of Taekwoon-do. We believe respecting ourselves and each other it is just as important as the techniques that we learn.

You will be required to learn the student oath:

  • I shall observe the tenets of Taekwondo.
  • I shall respect the instructor and seniors.
  • I shall be a champion of freedom and justice.
  • I shall build a more peaceful world.

The five Tenets of Taekwon-Do


You should attempt to practice the following elements of courtesy to build your character and conduct training in an orderly manner.

  • To promote the spirit of mutual concessions.
  • To be ashamed of one's vices, contempting those of others.
  • To be polite to one another.
  • To encourage the sense of justice and humanity.
  • To distinguish instructor from student, senior from junior, and elder from younger.
  • To behave oneself according to etiquette.
  • To respect other's possessions.
  • To handle matters with fairness and sincerity.
  • To refrain from giving or receiving any gift when in doubt.


You must be able to define right and wrong and have a conscience. For example, if you do something you shouldn’t, you feel guilt. Here are some examples from the Encyclopedia, of where integrity is lacking:

  • The Instructor who misrepresents himself and his art by presenting incorrect techniques to his students because of lack of knowledge or apathy
  • The student who misrepresents himself by 'fixing' breaking materials before demonstrations (i.e. cheats)
  • The Instructor who hides bad technique with luxurious training halls or false flattery to his students.
  • The student who requests rank from an instructor, or attempts to purchase it.
  • The student who gains rank for ego purposes or the feeling of power
  • The Instructor who teaches and promotes his art for materialistic gains.
  • The student whose actions do not live up to his words
  • The student who feels ashamed to seek opinions from his juniors.


There is an old Oriental saying, 'Patience leads to virtue and merit'. To achieve something, whether it is the next belt or the perfection of a technique, you must set your goal, then constantly persevere.


This tenet is extremely important inside and outside the Do-jang (training room), whether conducting yourself in sparring or in your personal affairs. A loss of Self-Control in free sparring can prove disastrous to both student and opponent. An inability to live and work within your capability or sphere is also a lack of Self-Control.

According to Lao-Tzu 'the term stronger is the person who wins over oneself rather than someone else.'

Indomitable Spirit

Indomitable Spirit is shown when a courageous person and their principles are up against overwhelming odds.

For example, if you believed that a wrong had been done, or an injustice carried out, your indomitable spirit will always show through to try to correct that injustice.
