Luther Standing Bear said this quote
“ Now all these virtues mean one thing, and that is bravery. A Sioux boy was taught to be brave always. It was not sufficient to be brave enough to go to war. He must be brave enough to make personal sacrifices and to think little of personal gain. To be brave was the supreme test of a Sioux boy, and this bravery might receive a greater test in times of peace than in times of war. ”
