Health and longevity of practitioners are the major goals of Tang Soo Do practice. Consequently, serious injuries are counterproductive because they retard a level of physical training that is needed to foster emotional and intellectual growth. However, minor injuries, such as bumps, bruises and the occasional loss of wind may be invaluable experiences. Each match should begin and end with respect, compassion and a deep appreciation for the opponent. Though Tang Soo Do sparring is competitive, traditional competitions are more of an exercise, or way of developing the self, than they are a competitive and game-like forum. Introspection and personal growth are fostered through free sparring.
