Warrior Spirit
Warrior spirit or maybe the closer or lesser form of it is the spirit of chivalry, is a spirit that is permeated by men in their destiny in becoming a warrior.
Warrior as in many culture, is the man of war. A soldier, a knight, a chevalier, whatever name he has. It is a spirit in regarding another man as rival or enemy and the willing to protect oneself and community against any manly threats.
A man as he is not below any men although he can work in a team regards other men not in permissive manner as he is with a woman. It is a code of man to believe in his strength and use it or test it from time to time against another man in a combat or duel.
Wrestling, sumo, bare hand fights, sword fight, gun fight, anything can be the confident of a man and thus is tested against another man's.
A man is a knife. And a knife fights with another knife to prove itself more and to sharpen its own iron.
