This journey can be described as a "pilgrimage". Critically discusses this word as a description of khumalo's journey

I think this has to do with Kumalo going to find his child: a pilgrimage for a parent.

Who indeed knows the secret of the earthly pilgrimage? Who knows for what we live, and struggle, and die? Who knows what keeps us living and struggling, while all things break about us? Who knows why the warm flesh of a child is such comfort, when one’s own child is lost and cannot be recovered?
