Courtesy (Yelu)
To promote the spirit of mutual concessions

• To be ashamed of ones voices, contemplating those of others
• To be polite to one another
• To encourage a sense of justice
• To distinguish instructor from student and senior from junior

Integrity (Yom Chi)
In Taekwondo, integrity means being able to define right from wrong and have the conscience, if wrong, to feel guilt.

• The instructor who misrepresents himself and his art by presenting improper techniques to his students because of lack of knowledge, or because of apathy
• The student who misrepresents himself by “fixing” breaking material
• The student who requests rank from an instructor, or attempts to purchase rank
• The student who gains rank for ego purposes or the feeling of power
• The instructor who promotes the art for materialistic gains

Perseverance (In Nae)
There is an old Oriental saying: “Patience leads to virtue or merit”. A serious student must learn not to be impatient: to continue steadfastly, to persevere.

Self Control (Guk Gi)
This tenet is extremely important inside and outside of the DoJang whether conducting one’s self in free sparring or in one’s personal affairs. A loss of one’s self-control can prove disastrous to both the student and opponent. An inability to work within one’s capability is also lack of self-control.

Indomitable Spirit (Baekjul  Boolgool)
A serious student will at all times be modest and honest. If confronted with injustice, he will deal with the belligerent without fear or hesitation and with an indomitable spirit, regardless of whomever or how many the number may be.
