Answer:
In Black Elk's vision, he saw a "sacred herb". The herb he used in the curing of his people. The "black road" symbolized following the bad way of life, a life with no rules and order. The "good red road" symbolized the way Black Elk wanted his people to live and how they lived before the Wasichus came. The "good red road" is the good way of life. The Indians lived as one people and shared a set of common rules, a code.
