We Could learn from Hopi Way
Theoretically, the United States Constitution protects the Indian's right to his faith. Though the Kachina dances may seem barbaric and pagan to the random visitor, they are in reality part of a pure religion—visible prayers in motion. Without these expressions of the faith, the Pueblo would lose their identity.
The Hopi Way deserves our profound respect. From the calm and peaceful Indian we can learn much about the things that are free—laughter and happiness, inner discipline, and the enjoyment of sunlight on vast spaces and starlight on rooftops.
