James Vukelich Kaagegaabaw's new book, "The Seven Generations and Seven Grandfather Teachings," shows how language carries cultural wisdom.

While Ojibwe is spoken across southern Canada and the Upper Midwest, the language is considered severely endangered. Since Minnesota is home to the greatest concentration of fluent Ojibwe speakers, the state has cultivated many revitalization efforts, including those of James Vukelich Kaagegaabaw, 48, who lives in Apple Valley with his wife and son.
