War Horse

... Native American boys go through a test, as it is, to see if they are ready to be a man.

Different tribes have different ways of doing this.  This man has taken the proper time to sweat in the sweat lodge, he has fasted.  He may have spent time out alone for many nights to receive his personal medicine.  He may be even participated in the Sun Dance Ceremony.  Having not eaten, and going through the sweat.  Also participating in the Sun Dance, he is in a state of purity, and is ready to receive the Creators gift of the vision.

This man's medicine is the vision of the fighting horses.  This is his magic, his medicine, and he has adopted the name War Horse.  He will be a mighty Warrior for his people.
