"Here lie 300 who did their duty", a simple epitaph for one of the greatest acts of courage known to mankind. Although facing the superior forces of Xerxes, Leonidas and his 300 Spartans at Thermopia showed the world the meaning of Indomitable Spirit. It is shown when a courageous person and his principles are pitted against overwhelming odds. A serious student of Tae Kwon-Do will at all times deal with the belingerent without any fear or hesitation at all, and with Indomitable Spirit, regardless of whosoever and however many the number be.
