Mesa Verde Wild Horses
"As a Native American symbol, the Horse symbol meanings combine the grounded power of the earth with the whispers of wisdom found in the spirit winds. The Horse has long been honored has helper, messenger, and harbinger of spirit knowledge to the Native American. Considered wild and an emblem of freedom, the Native American sees many potentialities in the symbolic nature of this noble creature.
Another aspect of Native American symbol meanings of the horse comes with the understanding that the wild freedom of the Horse can be harnessed and used to the benefit of the tribe. This understanding comes only when man and beast enter a silent contract – acknowledging mutual respect and awareness of responsibility to each other."
