The Hwarang Five Codes of Human Conduct are:
- Loyalty to your country
- Obedience to your parents
- Trustworthiness to your friends
- Courage to never to retreat from the enemy
- Justice never to take a life without cause
The codes became a way of life for the young men and guided their moral behavior and the use to which they put their Subak training. The codes formed the philosophical background for modern Taekwondo, which is reflected in the so-called Eleven Commandments of Taekwondo. As with the original five codes, these modern axioms are used to guide the moral development of Taekwondo students. Students must fully understand these tenets to master the true essence of Taekwondo.
