Warriors always painted themselves with their own spiritual protective designs when they went into battle, but not all body painting was done for the purpose of war. Some tribes painted their faces for protection against wind, sun, snow and insects. They also did is as a favorite way of mental conditioning. The Sioux believed that by being painted they had been changed or undergone a “new birth”, and new responsibilities, obligations and relationships would then be assumed. The painting was done in a hidden place, away from others so that the painted one would come forth pure, free of ignorance, and at one with the Great Spirit.
