as not too far as i know: (i've read a little & trained a little)
many Martial Art Schools - especially in past - put emphasis on training Warrior's Spirit, to prepare a Man to overcome obstacles & survive hardships in life.
but in real fight, combat skill is much more effective.
to defeat opponent in combat, most natural way is to learn proper combat skill first.
but the Warrior's Spirit is useful in any type of combat.
