What is the biggest principle in Karate and Taekwondo?

Since some people said that Karate and Taekwondo have principles and theories. I would like to ask what they are. Don%26#039;t start giving me techniques. I don%26#039;t mean tenets also.|||What are you talking about then, give an example of a %26quot;principal%26quot;|||Probably that karate is to be only as self defense or the defense of a loved one.|||Karate%26#039;s main principle is the cultivation of mind-body-spirit, known as Sanchin, or the %26quot;Three-Conflicts.%26quot; Through your life you fight the battle of mind, especially later in life as your memory starts to go. As your body naturally ages, you fight the battle of body with karate kata and other exercises. And finally, you fight the battle of spirit, Breath, through the meditations of Karate.


I don%26#039;t know what principles Taekwondo are based on, but it is an Olympic sport, so maybe getting to the Olympics and winning a medal is a principle.
