What does Bruchac's title suggest

Joseph Bruchac's title "The Sun Still Rises in the Same Sky" conveys the Native Americans' holistic view of the world. In spite of all the changes, nature itself never changes. It survives everything. It will survive humans' interference as well. The changes are inherent to its perpetuity; even though they happen all the time, they don't change the natural order of things and the fact that nature is always going to exist.
